CROSS-REFERENCE TO RELATED APPLICATION(S)

Pursuant to 35 U.S.C. §119(a), this application claims the benefit of earlier filing date and right of priority to Korean Application No. 10-2015-0107532, filed on Jul. 29, 2015, the contents of which is incorporated by reference herein in its entirety.

BACKGROUND

The present disclosure relates to a mobile terminal capable of controlling an unmanned aircraft, and a method for controlling the same.

A mobile terminal includes all types of devices provided with a battery and a display unit and carried by a user. The devices are configured to output information to the flexible display unit using power supplied from the battery. The mobile terminal includes a device for recording and playing moving images, a device for displaying a graphic user interface (GUI), etc., which includes a notebook, a mobile phone, glasses, a watch, a game console, etc.

Such mobile terminal has become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other mobile terminals are configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs. Various attempts have been made to implement complicated functions in such a multimedia device by means of hardware or software.

Recently a technique to capture an object on the sky using a camera installed to an unmanned aircraft has been developed. However, there has been a difficulty in controlling one by one capturing by the unmanned aircraft which flies far from a user to the sky, and since it is not possible to continually grasp a flight state of the unmanned aircraft which is in-flight, there has been inconvenience in that a user must find out and set a spot where capturing is erroneously made in order to correct images which have been erroneously captured in-flight.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a mobile terminal and a method for controlling the same capable of controlling a flight for recapturing of an unmanned aircraft in order to obtain a captured image of high quality using an unmanned aircraft.

To achieve these and other advantages and objects of the present invention, there is provided a mobile terminal which wirelessly communicates with an unmanned aircraft provided with a camera, including: a wireless communication unit configured to receive a captured image including a plurality of images captured by the camera; a memory configured to store flight information of the unmanned aircraft corresponding to each of the plurality of images; a display unit configured to output the captured image; and a controller configured to transmit a flight control command which is formed by flight information corresponding to at least one image to the unmanned aircraft, based on a recapturing command to at least one image among the plurality of images.

In one embodiment, the display unit may be configured to output a map screen including a flight route based on the recapturing command, the controller may be configured to set the recapturing route based on a touch applied to the map screen, and to output an image corresponding to the flight route. Thus, a user may set the recapturing route while checking the captured image.

In one embodiment, since the controller may select an error image or generate the recapturing command based on a touch applied to the captured image, it is possible to immediately execute a recapturing, while checking the captured image which is transmitted real time from the unmanned aircraft which is in-flight.

In one embodiment, since it is possible to search a substitute image based on flight information corresponding to the error image, a captured image of more high quality can be obtained by a synthesis when it is difficult to acquire a desired image through a recapturing.

In one embodiment, since a flight control command is generated using flight information which is stored with an image forming a captured image, a user does not need to set a position where the unmanned aircraft will fly to recapture at the same position.

As a result, a user may immediately recapture a desired image and it is possible to capture an image at the same position, though a position where the corresponding image is captured is not correctly set.

The accompanying drawings are used to help easily understood the technical idea of the present invention and it should be understood that the idea of the present disclosure is not limited by the accompanying drawings. In the following description, explanations will be made in order in the clockwise direction based on the drawing in a right upper side.

The sensing unit140is typically implemented using one or more sensors configured to sense internal information of the mobile terminal, the surrounding environment of the mobile terminal, user information, and the like. For example, inFIG. 1A, the sensing unit140is shown having a proximity sensor141and an illumination sensor142.

The power supply unit190can be configured to receive external power or provide internal power in order to supply appropriate power required for operating elements and components included in the mobile terminal100. The power supply unit190may include a battery, and the battery may be configured to be embedded in the body, or configured to be detachable from the body.

At least some of the above components may operate in a cooperating manner, so as to implement an operation or a control method of a glass type terminal according to various embodiments to be explained later. The operation or the control method of the glass type terminal may be implemented on the glass type terminal by driving at least one application program stored in the memory170.

Referring still toFIG. 1A, various components depicted in this figure will now be described in more detail.

The power supply unit190receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal100. The power supply unit190may include a battery, which is typically rechargeable or be detachably coupled to the body for charging.

The display unit151is shown located on the front side of the body to output information. As illustrated, a window151aof the display unit151may be mounted to the front case101to form the front surface of the body together with the front case101.

The second camera121bis shown located at the rear side of the body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit121a. If desired, second camera121amay alternatively be located at other locations, or made to be moveable, in order to have a different image capturing direction from that which is shown.

At least one antenna for wireless communication may be located on the body. The antenna may be installed in the body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module111may be retractable into the body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover103, or a case that includes a conductive material.

The mobile terminal according to an embodiment of the present invention may wirelessly communicate with an unmanned aircraft and control the function of the unmanned aircraft. Here, the unmanned aircraft is an aircraft which does not use a runway, and has a relatively light-weight body which can transport things, capture images, perform a low altitude reconnaissance, and may be loaded with various functions.

The mobile terminal according to an embodiment of the present invention may generate a control command for controlling flight of an unmanned aircraft, and also generate a control command for controlling a camera which is configured to capture external environment while flying, among various electronic parts loaded on the unmanned aircraft.

Hereinbelow, a method for controlling various functions of an unmanned aircraft using the mobile terminal, will be described.

FIG. 2Ais a flowchart illustrating a control method according to an embodiment of the present invention, andFIG. 2Bis a view illustrating the control method ofFIG. 2Aaccording to an embodiment of the present invention.

Referring toFIGS. 2A and 2B, a captured image including a plurality of images captured by a camera of an unmanned aircraft10is received (S210). The controller180is wirelessly connected with the unmanned aircraft10and may control the wireless communication unit110to receive the captured image real time when external environment is acquired by the camera. The mobile terminal100may include an application for controlling the unmanned aircraft10. When the application is executed, the controller180may wirelessly communicate with the unmanned aircraft10and receive an image acquired by the camera.

The captured image510may include a plurality of images. Since a capturing range of the camera is varied based on movement of the unmanned aircraft10, the captured image510may include a plurality of images which are sequentially captured.

The controller180may control the memory170to store flight information of the unmanned aircraft10corresponding to each of the plurality of images (S220). Here, the flight information may include a flight position, a flight speed, an altitude, a direction, and an operation condition (residual amount of battery, a capturing mode of camera, and the like) of the unmanned aircraft10at the time point of capturing the corresponding image. The unmanned aircraft10may transmit the flight information at a preset time interval together with the captured image. The memory170may store the flight information in correspondence to the plurality of images.

The display unit151outputs the received captured image510(S230). The captured image510is changed based on movement of the unmanned aircraft10. When the application is executed, the display unit151outputs the captured image510to the execution screen. The execution screen may include at least one icon for controlling the unmanned aircraft10. For instance, the execution screen may include an icon for controlling flight of the unmanned aircraft10or capturing of the camera installed to the unmanned aircraft10.

As shown inFIG. 2B, the controller180generates a control command for controlling the camera of the unmanned aircraft10based on a touch applied to the icon included in the execution screen. The unmanned aircraft10may capture (store) images which are acquired by the camera, based on the control command. After the control command is applied, the display unit151may continually output the captured images and output a graphic image indicating that the captured images are being stored.

The controller180transmits a flight command by the flight information to the unmanned aircraft10based on a recapturing command to at least one image among the plurality of images (S240). The recapturing command may be applied while the captured image510is outputted.

For instance, as shown inFIG. 2B, when a specific type of touch is applied to the display unit151while the captured image510is outputted, the recapturing command is generated. The specific type of touch may correspond to a long touch input which is applied for a specific time (several seconds). That is, a user may generate the recapturing command by applying a touch while viewing the captured images received from the unmanned aircraft10. For instance, when an obstacle which is located near the camera of the unmanned aircraft while the unmanned aircraft10is in flight and the obstacle is included in the captured image, the user may confirm the obstacle-included captured image and apply real time a recapturing command.

The display unit151outputs a map screen610based on the recapturing command, and may output the recapturing screen610together with the map screen510. The controller180outputs the map screen610using flight information corresponding to an image which is outputted to the display unit151at the time point that the recapturing command is applied. The map screen610may indicate a position of the unmanned aircraft10at a time point that the image has been captured.

The unmanned aircraft10may stop a flight or continuously fly along a preset flight route when the recapturing command is received. When the unmanned aircraft10continuously flies after the recapturing command is received, the captured image510which has been captured by the camera of the unmanned aircraft10may be continually outputted.

The display unit151may output at least one thumbnail image710corresponding to part of the plurality of images. The thumbnail image710corresponds to images which are captured at a time point close to a time point that the recapturing command is applied. The controller180may select images to be recaptured by the thumbnail image710. The controller180may generate a flight route for recapturing based on an image outputted at the time point that the touch is applied and a touch applied to the thumbnail710, and display the flight route on the map screen610. The display unit151may display an icon, which receives a touch in order to execute recapturing, on the map screen610.

The controller180generates a flight control command using flight information corresponding to the selected image. The flight information may include a position, an altitude, a flight direction and a capturing angle of the camera of the unmanned aircraft10at the time of capturing the selected image.

The controller180may receive a captured image which is re-captured by the camera of the unmanned aircraft10and output to the display unit151. Further, the display unit151may display a flight route corresponding to flight of the unmanned aircraft10on the map screen610.

However, the present invention is not limited to this, but only a captured image which is acquired by the camera may be displayed on the display unit151when recapturing of the unmanned aircraft10is executed.

Though not shown specifically, the unmanned aircraft10is controlled to move along the preset flight route when the recapturing is finished, or return to a position of the time point that the recapturing command is applied. When the recapturing is finished, the controller180re-receives the captured image which is captured while flying to the preset flight route and controls the image to be outputted to the display unit151.

According to an embodiment of the present invention, a user can immediately perform recapturing by applying a recapturing command to the display unit151, while outputting an image which has been captured by the unmanned aircraft10during flying. Further, since the controller180generates a flight control command using flight information which is stored with images, a user does not need to select a position where the unmanned aircraft10is to be flown to recapture at the same position.

As a result, a user can immediately recapture a desired image and capture an image at the same position though not setting an accurate position where the corresponding image is captured.

FIGS. 3A and 3Bare conceptual views illustrating a control method of the mobile terminal based on a recapturing command which is inputted while reproducing a capturing image.

Referring toFIG. 3A, a pre-stored image data may be reproduced. When the image data is reproduced, the plurality of images are continually outputted. While the plurality of images are outputted, a reproducing bar520aof the image data and an icon521for forming the recapturing command are outputted together. The reproducing bar520aindicates a degree that the image data is reproduced.

When a touch is applied to the icon521, the controller180generates a recapturing command using flight information corresponding to an image which is outputted at the time point that the touch is applied. Here, the touch applied to the icon521may correspond to a long touch input which is applied for a specific time. The controller180selects images which are outputted while the touch is applied to the icon521as target images to be recaptured, and stores flight information corresponding to the selected images. Meanwhile, the display unit151outputs a recapturing bar520bin correspondence to the reproduction bar520a. The recapturing bar520bindicates a time point that a touch is applied while a plurality of images are outputted as time passes. A region where the touch is applied is indicated as another form of the recapturing bar520b.

When the touch applied to the icon521is released or reproduction of the image data is finished, the controller180controls the display unit151to output a first confirmation window522for confirming recapturing for at least one image which is selected to be recaptured. The first confirmation window522may include a reproduction time which indicates a time point that the touch is applied among the image data.

According to an embodiment of the present invention, a user can select a desired image by applying a touch during outputting images to be recaptured, while reproducing the pre-stored image data, and check a region which is selected for recapturing while the whole image data are outputted.

Referring toFIG. 3B, the controller180may select a specific object included in the image based on a touch applied to the image among the image data. The controller180selects an object02displayed on a region where a specific type of touch is applied while the images are outputted as time lapses. The controller180extracts the selected object02and recognizes the extracted object02. When the object02is selected, the display unit151may display a specific configuration together with the object02. The object02may correspond to a moving configuration or a configuration which moves on the display unit151.

The controller180may control the display unit151to output a second confirmation window523for confirming recapturing of the images including the object selected by the touch. When a recapturing command is applied, the controller180may extract an image including the object among the image data, and generate a recapturing control command using flight information corresponding to the extracted image.

The unmanned aircraft10may fly by flight information corresponding to an image in which the object02is captured, based on the recapturing control command.

Meanwhile, the controller180groups the images in which the object02is captured. The controller180extracts the images in which the object02is captured, and groups the images which are captured at the similar time zone. The display unit151outputs a group image524indicating the grouped images. A recapturing control command on the images included in a group which is selected based on a touch applied to the group image524is generated.

Though not shown, it is possible to output a plurality of grouped images based on the touch applied to the group image524to the display unit151, and a recapturing command for recapturing only the selected image among the extracted images may be generated.

According to an embodiment of the present invention, when an obstacle is repeatedly detected while the unmanned aircraft10is in flight, it is possible to selectively capture an image including an object without requiring for a user to select individually an image including an object of the obstacle.

FIGS. 4A through 4Dare conceptual views illustrating a control method of the mobile terminal which detects an error image and generates a recapturing control command to the error image.

Referring toFIG. 4A, when a specific object is captured by the camera, the controller180may determine the captured image as an error image. For instance, when an object captured by the camera corresponds to a specific object which disturbs to capture external environment, the controller180may determine an image including the specific object as an error image. The specific object may correspond to a flying bird or another aircraft.

Alternatively, when the specific object is captured by the camera larger than a specific size, the controller180may determine the images including the specific object as an error image. For instance, when the object on the image occupies more than a specific ratio, the controller180may determine the object as an error image.

When the error image is detected, the display unit151may output a map screen610thereto. The map screen610may include information on the current position and flight route of the unmanned aircraft10. Further, the display unit151may output a map screen610including flight information captured with the error image together with the error image.

The controller180may control the wireless communication unit110to output a flight control command to stop flight of the unmanned aircraft10when the error image is detected, but not limited thereto. The unmanned aircraft10may capture external environment while moving along the preset flight route and transmit the captured image, while the display unit151outputs the error image and the map screen610.

The controller180may transmit a flight control command to recapture the error image to the unmanned aircraft10, after the map screen610is outputted. The controller180generates a flight control command such that the unmanned aircraft10moves again by the flight information corresponding to the error image. The controller180controls the display unit151to output a recaptured image501, while the camera of the unmanned aircraft10captures external environment using the flight information corresponding to the error image. The display unit151may output a map icon610′ together with the recaptured image501. The map icon610′ may include flight information of the unmanned aircraft10.

Thus, the mobile terminal100can control the unmanned aircraft10to extract and recapture an error image without a user's control command while the captured image is outputted. As a result, a user can acquire a desired captured image without applying an additional control command.

Referring toFIG. 4B, the controller180outputs the captured image510to the display unit151. The display unit151outputs a capturing bar520cwhile the captured image510is captured. The capturing bar520cindicates a capturing time and may be varied as the capturing time is longer.

When a specific object01is detected, the controller180selects the specific object01as an error image. The controller180outputs an error icon520dto the capturing bar520cwhen the error image is detected. It is possible to grasp the time point that the error image is detected by the error icon520d.

When a touch is applied to the error icon520d, the controller180controls the wireless communication unit110to transmit a flight control command to the unmanned aircraft10to stop flight. The display unit151outputs a thumbnail image710of the captured image. The thumbnail image710includes an error image711. The error image711is displayed in a different shape from other images. Though not shown, it is possible to select the thumbnail image710as an error image by applying an additional touch thereto.

Thus, a user can check the error image using the thumbnail image. When a recapturing command is applied in a state that the thumbnail image is outputted, the controller180generates a flight control command for controlling the unmanned aircraft10based on the flight information corresponding to the error image.

Meanwhile, when a touch is applied to the error icon520d, the controller180generates the flight control command based on the flight information corresponding to the error image. The controller180controls the display unit151to receive a recaptured image502which is captured based on the flight control command, and to output the recaptured image502.

Thus, a user can capture the recaptured image502without requiring selection of the error image when a touch is applied to the error icon520d.

Referring toFIG. 4C, when the image data is reproduced, the controller180outputs the image620and the reproduction bar520aof the image data as well. When an error image among the plurality of images included in the image data is detected, the controller180controls the display unit151to display an error icon621on one region of the reproduction bar520acorresponding to the error image.

The controller180may control the display unit151to output a third confirmation window622informing recapturing based on a touch applied to the error icon621. When the third confirmation window622is outputted, the controller180may control the wireless communication unit110to transmit a flight control command for stopping the unmanned aircraft10.

Thus, it is possible to display an error icon for the detected error image while the image data is outputted, and generate a recapturing command for recapturing the error image.

A control method for selecting an error image according to a flight condition of the unmanned aircraft will be described with reference toFIG. 4D.

The controller180receives flight information from the unmanned aircraft10together with the captured image. When an abnormal data is detected from the flight information, the controller180selects the image corresponding to the relevant flight information as an error image. For instance, vibration, flight speed, flight direction, rapid variation of altitude over a specific standard, variation of inclination of the unmanned aircraft sensed by sensors, or the like may be detected by the flight information.

The unmanned aircraft10according to an embodiment of the present invention may include a movement sensing unit including a gyro-sensor for sensing a movement, an accelerometer, and the like. When a movement is sensed by the movement sensing unit, the unmanned aircraft10may transmit the sensed movement to the mobile terminal.

When an abnormal data is detected, the controller180may generate a recapturing command based on the flight information from which the abnormal data is detected. The unmanned aircraft10returns to the original flight route based on the recapturing command, and may acquire the recapturing command based on the flight information at the time that the abnormal data is generated. Thus, in an exceptional case where the unmanned aircraft10waivers by an external environment (wind, vibration or the like), or is temporarily collided with an obstacle, a user's control command can detect such a situation and generate a recaptured image.

The display unit151may output the recaptured image501, and a map icon610′ including the flight route601of the unmanned aircraft10for recapturing.

Though specifically not shown, the unmanned aircraft10is controlled to fly along a preset flight route when a flight for recapturing is terminated, and in this instance, the map icon610′ may disappear.

Further, when an image is recaptured without a user's control command, the controller180may control the memory170not to store the pre-captured image.

According to embodiments of the present invention, when an error image is expected to be captured during capturing an image, it is possible to immediately recapture without a user's control command, so that a high quality image can be provided even in a case where a user does not check the captured image.

FIGS. 5A through 5Dare conceptual views illustrating a control method for correcting an error image according to another embodiment of the present invention.

Referring toFIG. 5A, a capturing control method in an entry restriction area will be described.

When the unmanned aircraft10arrives at an entry restriction area, the controller180may receive an alarming sound801corresponding thereto. The entry restriction area may correspond to an area where the unmanned aircraft10is not allowed to enter without admission. For instance, the unmanned aircraft10may not fly to the entry restriction area, or may not be allowed to capture within the entry restriction area. The unmanned aircraft10is controlled to fly along another flight route beyond the entry restriction area. The display unit151may output a warning message801while the capturing image530received from the unmanned aircraft10is outputted.

The controller180may control the display unit151to output the map screen610together with the captured image530which is most recently received, after receiving the warning message801. The map screen610may include a current position of the unmanned aircraft10and a flight route611which has been reset.

The controller180may change the flight route or the capturing range based on a touch applied to the map screen610.

Alternatively, when the unmanned aircraft10arrives at an entry restriction area where is allowed to enter, but not allowed to capture, a modified captured image530′ is outputted to the display unit151. The modified captured image530′ is outputted in an image with a visual effect such as pixilated or blurred. The modified captured image530′ is received from the unmanned aircraft10or modified by the controller180after receiving the captured image.

Otherwise, the unmanned aircraft10may be controlled to fly along a corrected flight route, without entering the entry restriction area. When the unmanned aircraft10arrives at an entry restriction area, the controller180sets real time a most nearest flight route, and transmits a flight control command so that the unmanned aircraft10may fly to the most nearest flight route. The display unit151outputs a map screen610including the corrected flight route611together with the captured image530which is captured while flying to the corrected flight route611. In this instance, a user can acquire continuous captured image without applying a separate control command.

Referring toFIG. 5B, a control method when the unmanned aircraft arrives at an altitude restriction area will be described. When the unmanned aircraft10arrives at an altitude restriction area, the controller181receives a warning message801and transmits the warning message801to the display unit151.

The unmanned aircraft10is controlled to fly at a low altitude when arrived at an altitude restriction area. When the warning message801is received, the controller180transmits a flight control command to the unmanned aircraft10to fly at a specific altitude. Thus, the controller180controls the display unit151to output a captured image531at a lower altitude than a preset altitude.

Otherwise, the controller180transmits a flight control command to stop the unmanned aircraft10when arrived at the altitude restriction area. The display unit151outputs a most recently captured image530and the map screen610. On the map screen610, current flight information612of the unmanned aircraft10is outputted.

According to the embodiment of the present invention, since a user can immediately be provided with other captured images, or set another flight route when the unmanned aircraft10arrives at an altitude restriction area, it is possible to prevent from capturing being suddenly stopped or an error image from being generated.

Referring toFIG. 5C, a control method for synthesizing an error image with a substitute image will be described.

The display unit151outputs a captured image540which is received from the unmanned aircraft10. The captured image540may include a specific object541. The controller180analyses the specific object541included in the captured image540, and controls the display unit151to output a confirmation window802to confirm the recapturing when recapturing of the specific object541is needed.

The specific object541may correspond to an object which is set by a user, but not limited thereto. The controller180collects information of an object included in the captured image540, and outputs the confirmation window802when it is determined that the shape or position of the object has an error. For instance, when the object is a building, it is determined that the building is under construction or part of the building is destroyed, and it may be determined by the collected information of the object. The controller180may detect whether or not an error is included while the unmanned aircraft10flies or when the capturing image is reproduced.

The controller180generates a flight control command to fly and capture in another direction of the specific object based on the recapturing command. The controller180controls the display unit151to output a synthesis image540′ which is synthesized by the recaptured image542which is captured in another direction and the image which has been previously captured. For instance, when one side of the building is destroyed, it is possible to capture another side of the building and synthesize it with the corresponding destroyed side of the building.

According to the embodiment of the present invention, it is possible to provide a captured image by synthesizing a substitute image, even in a case where it is difficult to acquire an image of an object as the same region of the object is recaptured on account of a special situation of the object.

Referring toFIG. 5D, a control method for synthesizing an error image to a substitute image according to another embodiment of the present invention will be described.

The display unit151outputs a thumbnail image710together with the captured image643. The controller180may select one image711based on a touch applied to the thumbnail image710. The one image711is selected as an error image based on the touch.

The controller180analyzes the object included in the error image. For instance, the controller180analyzes the error image using flight information stored in correspondence to the error image and information of the objects included in the error image.

When specific error information is sensed in the error image, the controller180outputs a confirmation window for confirming an image synthesis. Here, the specific error information is information associated with a specific situation of the captured object or position, and may correspond to an area where is under construction, an area where is not allowed to enter, an area where an obstacle to disturb capturing is located, or the like. That is, the specific error information is distinguished from a flight error of the unmanned aircraft or a case that a temporary obstacle is captured.

The controller180searches a substitute image643′ from the specific server or memory170, based on flight information corresponding to an error image from which the specific error information is detected. The controller180may synthesize the substitute image643′ to the captured image.

Thus, a user can receive an image at a similar position from a server, or generate a synthesized captured image by searching an image which has been pre-captured by the unmanned aircraft when there is a possibility that an error image may be captured though a recapturing is executed.

FIGS. 6A and 6Bare conceptual views illustrating a control method for editing a recaptured image.

Referring toFIG. 6A, a control method to provide both the recaptured image and the initial image when the recaptured image is generated will be described. When the captured image data is reproduced, the display unit151may output a thumbnail image including an error image713while outputting the captured image510. The error image713corresponds to flight information which is substantially the same as the recaptured image. When the error image is plural, the error images are sequentially arranged and an error image corresponding to a recaptured image which is currently outputted may be highlighted.

Thus, a user can be provided with both the originally captured image (error image) and the image included in the completed captured image (recaptured image) simultaneously.

Referring toFIG. 6B, a control method for editing a recaptured image will be described. The display unit151outputs a thumbnail image730and a recaptured image732which are included in the captured image. The thumbnail image730may be arranged in a flow of time and sequentially outputted based on the user's touch.

The display unit151outputs a recaptured image732corresponding to the thumbnail image730. Images corresponding to the substantially same flight information are disposed to be closer to each other. The controller180may highlight the thumbnail image corresponding to the substantially same flight information when a touch is applied to the recaptured image732.

The controller180generates a corrected captured image by adding the recaptured image732to the thumbnail image730instead of the corresponding thumbnail image based on the specific type of touch applied to the recaptured image732.

According to the embodiment of the present invention, a user can be provided with both an original image and a recaptured image and selectively generate a captured image.

FIGS. 7A and 7Bare conceptual views illustrating a control method for setting a flight route of an unmanned aircraft for recapturing.

Referring toFIG. 7A, the controller180outputs the captured image530which is received from the unmanned aircraft10to the display unit151. The controller180generates a recapturing command based on a touch applied to the captured image530and set a flight route.

For instance, the touch corresponds to a dragging type touch which is applied in one direction. The controller180generates a flight control command to return the unmanned aircraft10to the preset flight route based on the touch.

The controller180determines a range to return along the flight route based on the range of the touch. The display unit151may re-output the captured image which has been recaptured, based on the applied touch. Thus, a user can generate a recapturing command by selecting a recapturing region while checking the recaptured image.

The controller180may generate a recapturing command based on the flight information corresponding to an image at the time of releasing when the touch is released.

Referring toFIG. 7B, the controller180outputs the map screen610together with the captured image530, based on a touch applied to the captured image530. The map screen610includes a flight route611of the unmanned aircraft10. The display unit151outputs an image613corresponding to the flight information of the region where the touch is applied based on the touch applied to the flight route611. The image613may be displayed on one region of the map screen610.

Thus, a user can check the images which are captured while flying.

When a touch is applied to one region of the flight route611, the controller180controls the display unit151to output the recapturing icon614. When a touch is applied to the recapturing icon614, the controller180receives a touch applied to the flight route. The controller180sets a flight route for recapturing, based on the touch applied to the flight route. The touch corresponds to a dragging type touch which moves along the flight route. The display unit151may display a recapturing route615by changing the flight route to which the touch is applied.

Thus, a user can confirm the images corresponding to the flight route, and may set a recapturing range on the flight route when recapturing is needed.

FIGS. 8A through 8Care conceptual views illustrating a scheme for setting a recapturing route.

Referring toFIG. 8A, an icon533for setting a flight route of the unmanned aircraft10is outputted together with the captured image530. When a touch is applied to the icon533, the display unit151outputs a map screen610together with the captured image530. The map screen610includes a flight route of the unmanned aircraft10.

The controller180may set a flight route of the unmanned aircraft10by applying a touch to the map screen610. However, the controller180may generate a recapturing command based on a touch applied to the flight route611.

Further, the controller180may change a flight route based on a touch applied to the flight route611. For instance, when a dragging type touch is applied to the flight route611, a modification route611′ is outputted to the map screen610. The controller180may generate a recapturing command using the modification route611′.

Thus, a user can be provided with a recaptured image which is captured at a route different from the existing route.

Referring toFIG. 8B, described will be a control method for generating a recapturing route when a plurality of error images are selected. The display unit151may sequentially output a plurality of thumbnail images710which generate the captured image530, while reproducing the captured image530. The controller180controls the display unit151to display an error image711which is selected for recapturing. The error image711may be outputted by adding a visual effect which is different from the other thumbnail image710. The error image711may be selected based on a touch which is applied in a state that the thumbnail image711is outputted, or classified as an error image based on detected specific information.

When an error image is included in the thumbnail image710, the controller180controls the display unit151to output a confirmation window805for confirming recapturing. When a recapturing command is generated, the display unit151outputs a map screen610.

The map screen610includes a flight route of the unmanned aircraft10. The display unit151displays a recapturing position612on the flight route611, using flight information corresponding to the plurality of error images711. The controller180may generate a flight control command for acquiring a recaptured image corresponding to the error image711, while flying along the flight route.

Alternatively, the controller180may generate a recapturing route611acorresponding to the error image711, based on the user's control command. The controller180may set a shortest flight route using the flight information.

According to the embodiment of the present invention, a user can first select an error image to be recaptured, and control the unmanned aircraft to perform a recapturing using a shortest flight route.

Referring toFIG. 8C, described will be a control method for recapturing based on a residual amount of battery of the unmanned aircraft10which is controlled by the mobile terminal100.

The controller180selects an error image using the thumbnail image710which is outputted with the captured image510. For instance, the controller180may select the error image based on a dragging type touch applied to the thumbnail image710.

The controller180sets a flight route using flight information corresponding to the selected error image. When it is determined that a power for flying to the flight route is insufficient based on the residual amount of battery of the unmanned aircraft10, the controller180controls the display unit151to output a route message.

Further, when it is determined that a power of battery is insufficient, the controller180controls the display unit151to output a map screen610. The map screen610includes a recapturing route615based on the flight information and a flight-enabled route616based on the residual amount of battery.

Thus, a user can generate a flight control command for enabling the unmanned aircraft10to fly within the flight-enabled route or cancel the recapturing.
