Title: Method and system for generating 3d synthetic image by combining body data and clothes data

Description:
TECHNICAL FIELD 
     The present invention relates to a method and a system for generating a 3D manipulated image acquired by combining physical data and clothing data. 
     BACKGROUND ART 
     Modern people who emphasize personality have become generalized to use the Internet as a means of acquiring information to find current trendy fashion and fashion suitable therefor. Due to this trend, a variety of shopping malls have emerged on the Internet, and one of the most popular fields is clothing and a fashion product mall including the same. Users purchasing fashion products using the Internet make full use of the temporal and spatial freedom provided by the Internet to purchase and use desired products without using any physical effort at a desired time. 
     When a user confirms an image provided on a web page of the fashion product mall and is interested in the image of a posted product, the user selects the image and confirms detailed information and purchase the product through the detailed information. 
     In such a purchase scheme, in the case of the fashion product, when a product that seems good in the image is received, the user often gets a different feeling from the image with respect to the image of the product, and as a result, the product is returned and turned back, which results in temporal and monetary damages to a mall operator, a product producer, and a product purchaser. 
     In order to solve such a problem, contrived is a method for providing fashion information through the Internet. The method of providing the fashion information through the Internet includes a method for providing a coordination service that displays user information in a database and compositing the product and a body form, or providing a coordination solution by creating a virtual model input by the user and pre-fitting a product selected by the user from image data regarding clothing products, that is, clothes, spectacles, shoes, caps, and the like. 
     However, since the coordination service on the Internet is provided by using the virtual model in a cyberspace rather than a real thing, when the user actually wears the fashion product such as the clothing or the cap, it may not be confirmed whether the product is in an entire harmony with his or her taste, physical characteristics, skin, and a hair color, and as a result, after the purchase of the product, the user is not satisfied with the product and the product is frequently returned. 
     In addition, a consumer goes to an off-line department store or shopping mall and tries to wear the clothing and thereafter, may not determine whether the clothing matches the consumer and when the consumer comes home and tries to wear the clothing after purchasing the clothing or frequently judges that the clothing does not match the consumer at the time of listening to opinions of other people. Therefore, the clothing is also frequently returned or exchanged. 
     The consumer tries the clothes offline and thereafter, may return the fashion product even after purchasing the fashion product and a natural result is that product satisfaction of the consumer with the fashion product purchased by the consumer on the Internet cannot but be much lower. 
     Due to these problems, an online shopping service is still inferior in reliability and satisfaction to the consumer.

       FIG. 1  is a diagram schematically illustrating a configuration of generating a 3D manipulated image according to an embodiment of the present invention. Hereinafter, the configuration of generating the 3D manipulated image will be described by using  FIG. 1 . 
     According to  FIG. 1 , the configuration of generating the 3D manipulated image includes a system operator server  100  and a user scanner  200  and the system operator server  100  includes a clothing data generating unit  110 , a 3D manipulated image generating unit  120 , a control unit  30 , a storage server  150 , and an input unit  140 . Further, the user scanner  200  includes a 3D scanner  205 , a communication unit  220 , a control unit  225 , an input unit  210 , and a storage unit  215 . Of course, another configuration other than the aforementioned configuration may be included in a configuration of generating the 3D manipulated image proposed by the present invention. 
     The system operator server  100  scans clothing by using the 3D scanner. The system operator server  100  generates scanning data regarding the scanned clothing. 
     The system operator server  100  generates clothing cloud data by using the generated scanning data. However, the present invention is not limited thereto and the system operator server  100  may generate point cloud data regarding a clothing data by using another apparatus other than the 3D scanner. Therefore, the system operator server  100  may generate the clothing point cloud data in a 3D image file provided from a clothing maker. 
     Hereinafter, data to generate a shape of the clothing may be defined as clothing cloud data, and the clothing cloud data may be configured by the point cloud data and configured by mesh data. However, when the cloud data is configured by the point cloud data, a capacity is small, and as a result, a data processing speed may be remarkably increased as compared with the mesh data or shape data. 
     The system operator server  100  generates clothing point cloud data or clothing mesh data to generate the shape of the clothing. To this end, sensors may be attached to the clothing at a predetermined interval and the attached sensors may measure a relative distance between the sensors through mutual communication between the sensors. The system operator server  100  generates the clothing cloud data by using relative distance information received from the sensors. However, the present invention is not limited thereto and the system operator server  100  may generate the clothing point cloud data by various methods other than the aforementioned method. 
     The system operator server  100  receives data regarding the clothing and a fabric through the input unit. That is, the system operator server  100  receives unique information regarding the clothing and the fabric through the input unit. This will be described below. 
     As described above, the system operator server  100  according to the present invention just generates the 3D manipulated image by using data regarding the shape or a color of the clothing and the unique information regarding the fabric used in making the clothing. 
     The user scanner  200  scans a whole body of a user. The user scanner  200  generates user point cloud data or user mesh data to generate a whole body shape of the user by using the generated scan data regarding the whole body of the user. The user scanner  200  receives the unique information of the user if necessary. The unique information of the user includes a name, an age (age range), a height, a weight, a gender, a hair color, a hair shape, and the like of the user. The user scanner  200  provides the user point cloud data and the unique information of the user to the system operator server  100 . 
     The system operator server  100  generates the 3D manipulated image by synthesizing the user point cloud data, the unique information of the user, and the stored clothing point cloud data received from the user scanner  200 . Of course, the system operator server  100  uses the unique information regarding the fabric in generating the 3D manipulated image. That is, when the received unique information of the fabric is different even though the user point cloud data and the clothing point cloud data are the same, a different image is also generated as the generated 3D manipulated image. Hereinafter, each component illustrated in  FIG. 1  will be described in detail. 
       FIG. 2  illustrates the configuration of a user scanner according to the embodiment of the present invention. Hereinafter, the configuration of the user scanner according to the embodiment of the present invention will be described in detail with reference to  FIG. 2 . 
     According to  FIG. 2 , the user scanner includes the 3D scanner, the input unit, the storage unit, the communication unit, and the control unit. Of course, another configuration other than the aforementioned configuration may be included in the user scanner proposed by the present invention. 
     The 3D scanner  205  scans the whole body of the user. The 3D scanner  205  provides information on the scanned whole body of the user to the control unit  225 . As described above, the user scanner may generate the user cloud data by using the sensors in addition to the 3D scanner. Herein, the cloud data may be configured by the point cloud data or the mesh data. 
     The input unit  210  receives the unique information of the user. As described above, the user&#39;s unique information includes the age, the gender, the height, the weight, the name, and the like of the user. Of course, another information other than the information may be included in the user&#39;s unique information. 
     The control unit  225  generates the user point cloud data by using the scan data received from the 3D scanner  205 . That is, the control unit  205  generates the user point cloud data having a relatively smaller data size than the scan data. Since the user point cloud data is data to recognize the shape of the user, the user point cloud data is smaller than the scan data. 
     The control unit  225  partitions an intersection distance measured between the respective sensors, which is received from the sensors into vertical and horizontal components, calculates a physical size of the user by combining positional relationships between the vertical and horizontal components, and generates the user point cloud data by using the calculated physical size of the user. 
     The control unit  225  calculates a projection distance which is a distance at which a central intersection point is projected from a plane formed by a mesh based on a diagonal distance which is a measurement distance from the sensors positioned at outer periphery intersection points which are eight intersection points positioned on outer peripheries of four adjacent meshes up to the central intersection point which is the intersection point at the center of four meshes. 
     Further, the control unit  225  increases the measured physical size by a predetermined amount and outputs the increased physical size when the projection distance is equal to or more than a predetermined threshold value. When the projection distance is contiguously generated at a predetermined number of times as the projection distance is progressed in horizontal and vertical directions, the control unit  225  increases the measured physical size by the predetermined amount and outputs the increased physical size. Further, it is preferable to use an ultrasonic distance sensor as the sensor. 
     The storage unit  215  stores the received user&#39;s unique information, scan data, and user point cloud data. Further, the storage unit  215  stores data required for driving the user scanner. 
     The communication unit  220  performs communication with the external system operator server  100 . The communication unit  220  transmits the data regarding the whole body of the user, which is scanned by the 3D scanner  205  to the external system operator server  100 . Of course, the communication unit  220  may transmit the user point cloud data in addition to the scan data. Besides, the communication unit  220  transmits the user&#39;s unique information to the external system operator server  100 . 
     The communication unit  220  receives the 3D manipulated image from the external system operator server  100 . Besides, the communication unit  220  transmits various information to the system operator server  100 . 
       FIG. 2  illustrates that the input unit  210  is included in the use scanner  200 , but the present invention is not limited thereto. That is, the input unit  210  may be included in a separate apparatus in addition to the user scanner. 
     The input unit  210  may select one of multiple clothes display in a display unit (not illustrated). That is, the display unit displays clothing to be synthesized with the body of the user, which is scanned by the 3D scanner. To this end, the display unit may divide and display the clothes into multiple groups. That is, the clothes may be divided into upper and lower clothes or displayed in various types including an inner wear, an overcoat, and the like. 
     The input unit  210  selects the clothing to be synchronized with the body of the user among multiple clothes displayed in the display unit. Of course, when necessary, the display unit may display detailed information regarding the clothing selected by the user. 
     The clothing (alternatively, clothing information) selected by the input unit  210  is transmitted to the external system operator server  100  through the communication unit  220 . When additionally described, when the number of clothes selected through the input unit  210  is at least two, whenever the clothing is selected, the information on the selected clothing may be transmitted to the system operator server  100  or when all clothes are selected, the information on the selected clothes may be transmitted to the system operator server  100 . As described above, the user may transmit the information on the clothes selected by various methods to the system operator server when necessary. 
       FIG. 3  is a block diagram illustrating the configuration of a system operator server according to the embodiment of the present invention. Hereinafter, the configuration of the system operator server according to the embodiment of the present invention will be described in detail with reference to  FIG. 3 . 
     According to  FIG. 3 , the system operator server  100  includes a clothing data generating unit  110 , a 3D manipulated image generating unit  120 , a control unit  130 , the input unit  140 , and a storage server  150 . Of course, another configuration other than the aforementioned configuration may be included in the system operator server proposed by the present invention. 
     The clothing data generating unit  110  may generate the clothing cloud data by scanning the clothing by means of the scanner. The clothing data generating unit  110  may generate the point cloud data or the mesh data. Further, the clothing data generating unit  110  may generate the point cloud data from a 3D image. 
     The storage server  150  stores information on the clothing scanned by the clothing data generating unit  110 . The storage server  150  stores the clothing point cloud data which is the point cloud data for the scanned clothing. Besides, the storage server  150  stores various information. That is, the storage server  150  stores the unique information in the fabric used in making the clothing input through the input unit  140 . The unique information regarding the fabric will be described below. 
     The input unit  140  receives the unique information regarding the fabric constituting the clothing and the unique information of the clothing. Herein, the unique information regarding the fabric may include a type and elasticity of a fiber, a thickness of fabric, a weight per area of the fabric, permeability of the fabric, a tensile strength, a tear strength, an abrasion strength, heat resistance, moisture mobility, firmness, drapability, peeling, filling, a spinning property, a strength of a thread, the spinning property, evenness of the thread, curving and bending characteristics, and fillability. Further, the unique information of the clothing may include the type, the use, a wearing portion, and the like of the clothing. The input unit  140  receives various information on the clothing. Further, the input unit  140  may receive various information including a price, an origin, a making date, and the like. 
     The control unit  130  controls an operation of the system operator server  100 . Further, the control unit  130  may include a reference point setting unit  131 , a reference point adjusting unit  132 , a point cloud data detail adjusting unit  133 , a direction calculating unit  134 , and a shape control unit  135 . 
     The reference point setting unit  131  sets a plurality of reference points among the clothing point cloud data. A reference point may be set at a predetermined interval and set at a portion which becomes a joint according to the shape of the clothing. 
     The reference point adjusting unit  132  calculates a distance between the reference points and moves the reference point. The reference point adjusting unit  132  calculates the distance between the reference points by combining the user point cloud data and the physical point cloud data and moves the reference point according to the calculated distance. 
     The point cloud data detail adjusting unit  133  adjusts the distance between the respective point cloud data from the reference point. The point cloud data detail adjusting unit  133  adjusts the distance between the respective point cloud data from the reference point and adjusts even the distance between the point cloud data. 
     The point cloud data detail adjusting unit  133  includes a physical analyzing unit, a clothing analyzing unit, a stress calculating unit, and an elasticity calculating unit. The physical analyzing unit calculates volumes of parts of the body of the user. The physical analyzing unit analyzes the volume by dividing the body of the user into the respective parts and for example, the physical analyzing unit may analyze the volume by dividing the body of the user into an arm, a chest, a shoulder, an abdomen, and the like. 
     The stress calculating unit calculates stress applied to the respective parts of the clothing. The stress calculating unit calculates a space which is accommodatable in the clothing and calculates and stores the stress applied to each clothing when the body is inserted into the clothing by the calculated space. The stress calculating unit may calculate the stress applied to the respective point cloud data. The elasticity calculating unit calculates an extensible distance for each part of the clothing by considering the unique information of the fabric and the shape of the clothing. 
     The direction calculating unit  134  sets a movement direction of the clothing point cloud data and calculates the movement direction of the clothing point cloud data by considering the stress applied to the clothing and the shape of the clothing. The movement direction of the clothing point cloud data may be determined by the stress and the elasticity. 
     The shape control unit  135  extracts a plurality of curvature points which contact the body from the clothing point cloud data and calculates a shape change of the clothing point cloud data at the curvature points. For example, the stress is not applied to the clothing by the body at a portion which contacts the shoulder, but the clothing droops by gravity, and as a result, the clothing shape is changed and the shape control unit  135  compares a length of the clothing and the length of the body with each other to calculate the shape change of the clothing. 
     Since the clothing point cloud data has a relatively smaller data capacity than the scan data of the clothing as described above, it may more efficiently to use the clothing point cloud data than to use the scan data. That is, the control unit  130  may generate data regarding clothes having different shapes by using the clothing point cloud data which has the relatively smaller data capacity. 
     The 3D manipulated image generating unit  120  generates the 3D manipulated image buy using the user point cloud data, the clothing point cloud data, and the unique information regarding the clothing according to a control command from the control unit  130 . The 3D manipulated image generating unit  120  generates the 3D manipulated data acquired by the body and the clothing of the user and generates a contour line from the 3D manipulated data and combines the colors to generate the 3D manipulated image. 
     As described above, the clothing point cloud data acquired b y converting the scanned data just represents only the shape of the clothing and may not express the color or a material of the clothing. Therefore, the 3D manipulated image generating unit  120  generates the 3D manipulated image by reflecting the scan data expressing the color or the material of the clothing to the clothing point cloud data. The reason for separating and 3D-synthesizing the scan data is that since the scan data has a larger capacity than the point cloud data, when a fitting process is performed by using the point cloud data having the small capacity, the clothing may be fitted to the body at a more rapid speed. 
     The unique information regarding the fabric and the clothing is numerically stored in the storage server  150 . The storage server  150  of the present invention stores the unique information regarding various fabrics and generates the 3D manipulated image by using the stored unique information. 
     That is, the existing 3D manipulated image may not show a unique characteristic with the clothing by just synthesizing the clothing with the body, but in the present invention, when the 3D manipulated image is generated, the 3D manipulated image is generated by reflecting the unique characteristics of the clothing and the fabric, and as a result, in spite of the clothes having the same shape and color, the 3D manipulated image showing different feelings according to the unique characteristics of the clothes may be generated. That is, the weight of the clothing having the relatively smaller thickness of the fabric may be smaller than that of the clothing having the relatively larger thickness. 
     The generated 3D manipulated image may be rotated at a predetermined speed so as to allow the user to know the feeling. When the generated 3D manipulated image may be rotated at the predetermined speed, the clothing having the relatively smaller weight moves (sways) more largely than the clothing having the relatively larger weight. The 3D manipulated image is rotated at the predetermined speed as described above to maintain a state relatively closest to a case where an actual user wears the clothing. 
     Further, the 3D manipulated image generating unit  120  generates the 3D manipulated image by using elasticity information of the fabric. That is, in spite of the clothes having the same shape, the 3D manipulated images are different from each other, which are generated according to the elasticity of the fabric. That is, in the case of clothing having the fabric which is high elastic (that is, excellent in stretchability), the clothing is in close contact with all planes of the body, while in the case of clothing having the fabric which is low elastic (that is, low in stretchability), the clothing is in close contact with the body only at a part of the body. In detail, in the case of the inner wear, since the clothing is made by the fabric having excellent elasticity, when the 3D manipulated image is generated, all planes of the clothing are in close contact with the body. In detail, in the case of the inner wear, since the clothing is made by the fabric having relatively low elasticity, when the 3D manipulated image is generated, some planes of the clothing are in close contact with the body. As described above, according to the present invention, the 3D manipulated image is generated by using various characteristics of the fabric used in making the clothing. 
       FIG. 4  illustrates an example of manipulating clothing manufactured by a fabric having different elasticity with a body according to the embodiment of the present invention. That is, referring to  FIG. 4 , the body wears two clothes and in particular, in the case of the wear positioned inside, an example of synchronizing the clothing made by the fabric having the relatively high elasticity with the body is illustrated and in the case of the clothing positioned outside, an example of synthesizing the clothing made by the fabric having the relatively low elasticity with the body is illustrated. 
     As described above, it can be seen that the clothing made by the fabric having the high elasticity is in close contact with the entirety of the body, while the clothing made by the fabric having the low elasticity is in close contact with a part of the body. 
     Further,  FIG. 5  illustrates an example of modifying the clothing point cloud data to which the physical point cloud data is reflected. As illustrated in  FIG. 5 , the clothing point cloud data CP is modified according to the physical point cloud data BP and the unique information of the clothing and the fabric to generate the 3D manipulated image. That is, it can be seen that a distance between coordinates (point clouds) constituting the clothing point cloud data CP is increased by reflecting the physical point cloud data BP and the unique information of the clothing and the fabric. The 3D manipulated data is generated by synthesizing the scan data with the generated 3D manipulated point cloud data. 
       FIG. 6  is a flowchart illustrating a method for generating a 3D manipulated image according to an embodiment of the present invention. Hereinafter, the method for generating the 3D manipulated image according to the embodiment of the present invention will be described in detail with reference to  FIG. 6 . 
     The method for generating the 3D manipulated image according to the embodiment includes a step (S 100 ) of generating user cloud data, a step (S 200 ) of generating clothing cloud data, a step (S 300 ) of adjusting a distance between the clothing cloud data, a step (S 400 ) of generating 3D manipulated data, and a step (S 500 ) of generating the 3D manipulated image. 
     In the step (S 100 ) of generating the user cloud data, since user point cloud data or user mesh data representing an outer shape of a body of a user is generated, physical cloud data may be constituted by point cloud data or mesh data. In a step of generating the user point cloud data, the user point cloud data may be generated by scanning the body of the user by using a user scanner  200 . 
     In the step (S 100 ) of generating the user cloud data, the user point cloud data or user mesh data to generate a whole body shape of the user is generated by using scan data regarding a whole body of the user, which is generated by using the user scanner  200 . 
     In the step (S 100 ) of generating the user cloud data, a projection distance is calculated, which is a distance at which a central intersection point is projected from a plane formed by a mesh based on a diagonal distance which is a measurement distance from the sensors positioned at outer periphery intersection points which are eight intersection points positioned on outer peripheries of four adjacent meshes up to the central intersection point which is the intersection point at the center of four meshes. 
     Further, in the step (S 100 ) of generating the user cloud data, the measured physical size is increased by a predetermined amount and the increased physical size is output when the projection distance is equal to or more than a predetermined threshold value. In the step (S 100 ) of generating the user cloud data, when the projection distance is contiguously generated at a predetermined number of times as the projection distance is progressed in horizontal and vertical directions, the measured physical size is increased by the predetermined amount and the increased physical size is output. 
     In the step (S 100 ) of generating the user cloud data, the received user&#39;s unique information, scan data, and user point cloud data are stored and data regarding the whole body of the user, which is scanned by the 3D scanner  205  is transmitted to the external system operator server  100 . 
     The method for generating the 3D manipulated image may further include a step of receiving the user&#39;s unique information and the user&#39;s unique information may include a name, an age (age range), a height, a weight, a gender, a hair color, a hair shape, and the like of the user. 
     In the step (S 200 ) of generating the clothing cloud data, the clothing cloud data representing the outer shape of the body of the clothing is generated, and as a result, the clothing cloud data may be constituted the point cloud data or the mesh data. 
     In the step (S 200 ) of generating the clothing cloud data, scanning data regarding the clothing may be generated by scanning the clothing by means of the scanner and the clothing cloud data is generated by using the generated scanning data. However, the present invention is not limited thereto and the system operator server  100  may generate the point cloud data regarding a clothing design by using another apparatus other than the 3D scanner. Therefore, the system operator server  100  may generate the clothing point cloud data in a 3D image file provided from a clothing maker. 
     Hereinafter, data to generate a shape of the clothing may be defined as clothing cloud data, and the clothing cloud data may be configured by the point cloud data and configured by mesh data. However, when the cloud data is configured by the point cloud data, a capacity is small, and as a result, a data processing speed may be remarkably increased as compared with the mesh data or shape data. 
     In the step (S 200 ) of generating the clothing cloud data, the clothing data generating unit  110  stores information on the scanned clothing and stores the clothing point cloud data which is the point cloud data regarding the scanned clothing. 
     In the step (S 300 ) of adjusting the distance between the clothing cloud data, the distance between the clothing cloud data is adjusted by combining the physical cloud data representing the body of the user, the clothing cloud data representing the clothing, the unique information of the fabric constituting the clothing, and the unique information of the clothing. 
     Herein, the unique information regarding the fabric may include a type and elasticity of a fiber, a thickness of fabric, a weight per area of the fabric, permeability of the fabric, a tensile strength, a tear strength, an abrasion strength, heat resistance, moisture mobility, firmness, drapability, peeling, filling, a spinning property, a strength of a thread, the spinning property, evenness of the thread, curving and bending characteristics, and fillability. Further, the unique information of the clothing may include the type, the use, a wearing portion, and the like of the clothing. 
     Further, as illustrated in  FIG. 7 , the step (S 300 ) of adjusting the distance between the clothing cloud data includes a step (S 301 ) of setting a reference point, a step (S 302 ) of adjusting the distance between the reference points, a step (S 303 ) of adjusting a detailed interval, a step (S 304 ) of setting a movement direction, and a step (S 305 ) of calculating a shape change. 
     In the step (S 301 ) of setting the reference point, a plurality of reference points are set among the clothing point cloud data. The reference point may be set at a predetermined interval and set at a portion which becomes a joint according to the shape of the clothing. 
     In the step (S 302 ) of adjusting the distance between the reference points, the distance between the reference points is calculated and the reference points are moved. In the step (S 302 ) of adjusting the distance between the reference points, the distance between the reference points is calculated by combining the user point cloud data and the physical point cloud data and the reference points are moved according to the calculated distance. 
     In the step (S 303 ) of adjusting the detailed interval, the distance between the respective point cloud data is adjusted from the reference point. In the step (S 303 ) of adjusting the detailed interval, the distance between the respective point cloud data is adjusted from the reference point and even the distance between the point cloud data is adjusted. 
     The step (S 303 ) of adjusting the detailed interval may include a step of calculating volumes of parts of the body of the user, a step of calculating stress applied to each part of the clothing, and a step of calculating an extensible distance according to a characteristic of the fabric. 
     In the step of calculating the volumes of the parts of the body of the user, the volume is analyzed by dividing the body of the user into the respective parts and for example, the volume may be analyzed by dividing the body of the user into an arm, a chest, a shoulder, an abdomen, and the like. 
     In the step of calculating the stress, the stress applied to the respective parts of the clothing is calculated. In the step of calculating the stress, a space which is accommodatable in the clothing is calculated and the stress applied to each clothing is calculated and stored when the body is inserted into the clothing by the calculated space. 
     In the step of calculating the stress, the stress applied to the respective point cloud data may be calculated. In the step of calculating the extensible distance according to the characteristic of the fabric, the distance which is extensible for each part of the clothing is calculated by considering the unique information of the fabric and the shape of the clothing. 
     In the step (S 304 ) of setting the movement direction, a movement direction of the clothing point cloud data is set and the movement direction of the clothing point cloud data is calculated by considering the stress applied to the clothing and the shape of the clothing. The movement direction of the clothing point cloud data may be determined by the stress and the elasticity. 
     In the step (S 305 ) of calculating the shape change, a plurality of curvature points which contact the body are extracted from the clothing point cloud data and a shape change of the clothing point cloud data is calculated at the curvature points. For example, the stress is not applied to the clothing by the body at a portion which contacts the shoulder, but the clothing droops by gravity, and as a result, the clothing shape is changed and in the step (S 305 ) of calculating the shape change, a length of the clothing and the length of the body are compared with each other to calculate the shape change of the clothing. 
     In the step (S 400 ) of generating the 3D manipulated data, the 3D manipulated data acquired by synthesizing the body and the clothing of the user is generated. In the step (S 500 ) of generating the 3D manipulated image, the contour line is generated from the 3D manipulated data and the color is combined to generate the 3D manipulated image. 
     The step of generating the 3D manipulated image may include a step of synthesizing first clothing point cloud data representing the outer shape of first clothing with the point cloud data of the user and a step of synthesizing second clothing point cloud data representing the outer shape of second clothing after synthesizing the first clothing point cloud data. Further, the size of the clothing corresponding to the second clothing point cloud data may be calculated according to the size of the clothing corresponding to the first clothing point cloud data and the thickness of the first clothing. 
     Further, in the step of generating the 3D manipulated image, when at least two clothes corresponding to the clothing point cloud data to be synthesized with the user point cloud data are selected, the clothing point cloud data corresponding two clothes selected according to the unique information of the clothing may be automatically synthesized with the user point cloud data in sequence. 
     The method for generating the 3D manipulated image may further include a step of rotating the 3D manipulated image at a set rotational speed after the step of generating the 3D manipulated image. A motion of the clothing constituting the 3D manipulated image may be expressed according to the unique information of the clothing corresponding to the clothing point cloud data synthesized with the user point cloud data. 
     In the 3D manipulated image wearing the clothing, the image may be rotated by dragging a mouse or a touch screen of a user terminal. Further, as described above, the clothing selected by using the unique information of the clothing is automatically synchronized with a corresponding location in the user point cloud data. 
     Besides, the 3D manipulated image may be made by various methods. As one example, when the clothing is selected and worn in the user point cloud data, primarily selected clothing is automatically combined and synthesized. Thereafter, when secondarily selected clothing is worn, the primarily selected clothing is worn on the user point cloud data to synthesize the secondary selected clothing with the user point cloud data by considering an increased thickness. By such a method, the 3D manipulated image may be implemented in such a manner that subsequently selected clothing is worn on the exterior of the previously selected clothing. Such a method is applied to implement the same effect as a case where actual clothing is worn. Further, since the clothing which is worn on the exterior of the previously selected clothing is worn by considering the thickness of the previously selected clothing as the size of the clothing which is worn on the exterior of the previously selected clothing, the clothing point cloud data may preferably be changed in various shapes as described above. 
     When additionally described, since a part of the clothing made by a fabric which is excellent in elasticity is stretched due to the elasticity when the thickness of the previously selected clothing (clothing which is internally actuated) is small, clothing having a larger size by one step need not be synthesized. However, since the clothing made by the fabric which is low in elasticity is not stretched even though the thickness of the previously selected clothing is small, clothing having the larger size by one step (alternatively, two steps or more) needs to be synthesized. As such, according to the present invention, the 3D image is generated by using the unique characteristics of the clothing and the fabric. 
     When the clothing may be worn on the user point cloud data through dragging and when the clothing is clicked by the mouse if necessary, the clothing may be automatically synthesized with the corresponding location in the user point cloud data by using the unique information of the clothing. 
     The method for generating the 3D manipulated image may include a step of storing the generated 3D manipulated image. In the storing step, the 3D manipulated image may be stored in a separate storage space. That is, after multiple 3D manipulated images are stored in the storage space, the corresponding 3D manipulated image may be called up or provided to a third person if necessary. Additionally, according to the present invention, the selected 3D manipulate image is transmitted to a clothing making company, and as a result, the selected clothing may be requested to be made. 
     As described above, the user may store the synthesized 3D manipulated image in the separate storage space and call up the 3D manipulated image stored in the storage space of another person under permission of another person if necessary. When additionally described, the clothing point cloud data is extracted from a registered clothing image of another person and the manipulated image is generated by synthesizing the extracted clothing point cloud data with the user point cloud data. Of course, in this case, the unique information of the clothing is reflected to generate the manipulated image. 
     As described above, even in the case where the clothing point cloud data and the user point cloud data are the same as each other, when the unique information of the clothing is different, different 3D manipulated images are generated. Besides, if necessary, the clothing point cloud data may be modified based on the user point cloud data. That is, when the user desires to make clothing acquired by partially modifying ready-made clothing, the clothing point cloud data is modified based on the user point cloud data. As described above, when the clothing point cloud data is partially modified, it is more preferable to use the clothing point cloud data having a relatively smaller data capacity than to use the scan data. When additionally described, the clothing point cloud data is partially modified based on the user point cloud data to generate the 3D manipulated image. 
     The present invention has bee described with reference to the embodiment illustrated in the drawings, but this is just exemplary and it will be appreciated by those skilled in the art that various modifications and other embodiments equivalent thereto can be made therefrom.
