Embodiment 2
This embodiment of the present invention provides a video processing method. The method provided by this embodiment of the present invention is elaborated with reference to the content of Embodiment 1. Referring to FIG. 2, a method process includes:
201: Acquire at least one three-dimensional image, and acquire a to-be-processed video.
This embodiment does not specifically limit the manner of acquiring the three-dimensional image. In specific implementation, a three-dimensional image designed by a user with a 3D Max tool may be acquired, and the three-dimensional image designed by the user is used as the acquired three-dimensional image. Certainly, apart from the foregoing three-dimensional image acquiring manner, other manners may also be used. For example, a locally stored three-dimensional image may be acquired, and the locally stored three-dimensional image acquired is used as the acquired three-dimensional image.
When multiple three-dimensional images are acquired, the method provided by this embodiment further includes, but is not limited to: acquiring a three-dimensional animation, and parsing the three-dimensional animation to obtain multiple three-dimensional images. This embodiment does not specifically limit the manner of parsing the three-dimensional animation. In specific implementation, the parsing manner includes, but is not limited to, parsing each frame of three-dimensional image in the three-dimensional animation.
Besides, this embodiment does not specifically limit the manner of acquiring the to-be-processed video. In specific implementation, a downloaded to-be-processed video may be acquired, and the downloaded to-be-processed video is used as the acquired to-be-processed video. Certainly, apart from the foregoing to-be-processed video acquiring manner, other manners may also be used. For example, a locally stored to-be-processed video is acquired, and the locally stored to-be-processed video acquired is used as the acquired to-be-processed video.
This embodiment does not limit the sequence of acquiring at least one three-dimensional image and acquiring a to-be-processed video. In specific implementation, at least one three-dimensional image may be acquired first, and then a to-be-processed video is acquired; alternatively, a to-be-processed video may be acquired first, and then, at least one three-dimensional image is acquired.
202: Parse the to-be-processed video, to obtain at least two video images.
Besides, this embodiment does not specifically limit the manner of parsing the to-be-processed video. In specific implementation, the to-be-processed video may be parsed by using a video codec, to obtain at least two video images. The video codec may be an FFMPEG; each video image obtained through parsing may be a frame of image in the to-be-processed video.
203: Parse each three-dimensional image, to obtain at least one three-dimensional model file, one three-dimensional model file corresponding to one three-dimensional image.
As an optional embodiment, the parsing each three-dimensional image includes, but is not limited to: creating a three-dimensional image model according to each three-dimensional image, and exporting each three-dimensional image model as a three-dimensional model file, that is, one three-dimensional model file corresponds to one three-dimensional image. This embodiment does not limit the format of the three-dimensional model file. In specific implementation, the format of the three-dimensional model file may be obj, md2, or the like, and each three-dimensional model file records image information, angle information, position information, and the like of one three-dimensional image model.
204: Generate at least two three-dimensional models according to each three-dimensional model file and each video image that are obtained through parsing.
As an optional embodiment, the generating at least two three-dimensional models according to each three-dimensional model file and each video image that are obtained through parsing includes, but is not limited to:
creating a three-dimensional space, and generating a three-dimensional sub-model in the three-dimensional space according to each three-dimensional model file obtained through parsing, to obtain at least one three-dimensional sub-model; and
determining a video image corresponding to each three-dimensional sub-model, and synthesizing, by using the video image corresponding to each three-dimensional sub-model as a background, each three-dimensional sub-model and the video image corresponding to each three-dimensional sub-model into a three-dimensional model, to obtain at least two three-dimensional models.
In order to generate a three-dimensional model in the three-dimensional space according each three-dimensional model file obtained through parsing, the method provided by this embodiment creates a three-dimensional space, and this embodiment does not specifically limit a specific form of the created three-dimensional space. In specific implementation, the created three-dimensional space includes, but is not limited to, a space consisting of a length dimension, a width dimension, and a height dimension. For example, the created three-dimensional space is a space rectangular coordinate system. A three-dimensional sub-model is generated in the created three-dimensional space according to image information, angle information, and position information, which are recorded in each three-dimensional model file, of one three-dimensional image model included in the three-dimensional animation, to obtain at least one three-dimensional sub-model.
Further, this embodiment does not limit the manner of determining the video image corresponding to each three-dimensional sub-model. In specific implementation, the determining manner includes, but is not limited to, determining the video image corresponding to each three-dimensional sub-model according to the number of three-dimensional sub-models and the number of video images.
Because the video image is obtained by parsing the to-be-processed video, while the three-dimensional model file is obtained by parsing the three-dimensional image, the number of video images obtained through parsing may be different from that of three-dimensional model files obtained through parsing, and further, because the number of three-dimensional sub-models is the same as the number of three-dimensional model files obtained through parsing, the number of video images obtained through parsing may be different from that of three-dimensional sub-models. When the video image corresponding to each three-dimensional sub-model is determined according to the number of three-dimensional sub-models and the number of video images, it may include, but is not limited to, the following two situations:
(1) The number of three-dimensional sub-models is less than that of video images.
Because one three-dimensional model file corresponds to one three-dimensional image, and one three-dimensional sub-model is generated in the three-dimensional space according to one three-dimensional model file, it can be considered that one three-dimensional image corresponds to one three-dimensional sub-model. In a case in which the number of three-dimensional sub-models is less than that of video images, a display duration of all three-dimensional images may be determined first, where the display duration is not greater than a display duration of the processed video; and a given number of video images are selected from the at least two video images, where a display duration of the given number of video images is equal to the display duration of all the three-dimensional images. If the number of selected video images is equal to that of three-dimensional sub-models, one three-dimensional sub-model corresponds to one selected video image, thereby determining the video image corresponding to each three-dimensional sub-model; if the number of selected video images is greater than that of three-dimensional sub-models, one three-dimensional sub-model corresponds to multiple selected video images.
This embodiment does not limit the manner of selecting a given number of video images from the at least two video images obtained through parsing. In specific implementation, to ensure the continuity of three-dimensional images in the processed video, the selecting manner includes, but is not limited to, continuously selecting a given number of video images from the at least two video images obtained through parsing. For example, when the number of video images obtained through parsing is 5, the number of three-dimensional sub-models is 2, and the selected video images are the second and third video images in the video images obtained through parsing, the first three-dimensional sub-model corresponds to the second video image, and the second three-dimensional sub-model corresponds to the third video image. For another example, when the number of video images obtained through parsing is 5, the number of three-dimensional sub-models is 2, and the selected video images are the second to fifth video images in the video images obtained through parsing, the first three-dimensional sub-model may correspond to the second and fourth video images, and the second three-dimensional sub-model may correspond to the third and fifth video images; in this manner, when the processed video is played, each three-dimensional image is played twice.
(2) The number of three-dimensional sub-models is equal to that of video images.
Because the number of three-dimensional sub-models is equal to that of video images, one three-dimensional sub-model may directly correspond to one video image, thereby determining the video image corresponding to each three-dimensional sub-model. For example, when the number of video images obtained through parsing and that of three-dimensional sub-models are both 5, the first to fifth three-dimensional sub-models separately correspond to the first to fifth video images.
Further, because the video image corresponding to each three-dimensional sub-model has been determined, by using the video image corresponding to each three-dimensional sub-model as a background, each three-dimensional sub-model and the video image corresponding to each three-dimensional sub-model can be synthesized into a three-dimensional model, to obtain at least two three-dimensional models. It should be noted that, because the video images are two-dimensional, the obtained three-dimensional models are a synthesis of the two-dimensional video images and the three-dimensional sub-model, that is, the video images in the three-dimensional model are still two-dimensional.
As an optional embodiment, after the determining a video image corresponding to each three-dimensional sub-model, the method further includes, but is not limited to:
determining position information and rotation angle information of a key object in the video image corresponding to each three-dimensional sub-model.
The determining position information of a key object in the video image corresponding to each three-dimensional sub-model includes, but is not limited to:
sorting the video images corresponding to the three-dimensional sub-models, and identifying position information of a key object in the first video image corresponding to the first three-dimensional sub-model; and
tracking, according to the identified position information of the key object in the first video image corresponding to the first three-dimensional sub-model, position information of a key object in a video image corresponding to another three-dimensional sub-model, to obtain the position information of the key object in the video image corresponding to each three-dimensional sub-model.
After the position information and the rotation angle information of the key object in the video image corresponding to each three-dimensional sub-model are determined according to the foregoing manner, the method provided by this embodiment synthesizes, by using the video image corresponding to each three-dimensional sub-model as a background, each three-dimensional sub-model and the video image corresponding to each three-dimensional sub-model into a three-dimensional model, which includes, but is not limited to:
converting, according to the position information and the rotation angle information of the key object in the video image corresponding to each three-dimensional sub-model, the position information of each key object into position information in the three-dimensional space;
converting each three-dimensional sub-model according to the position information, of the key object in the video image corresponding to each three-dimensional sub-model, in the three-dimensional space; and
synthesizing, by using the video image corresponding to each three-dimensional sub-model as a background, each converted three-dimensional sub-model and the video image corresponding to the three-dimensional sub-model into a three-dimensional model.
For ease of understanding, that the key object in the video image is a face is used as an example for description. The video images corresponding to the three-dimensional sub-models are sorted, and position information of a face in the first video image corresponding to the first three-dimensional sub-model is automatically identified by using a face recognition algorithm; and position information of a face in a video image corresponding to another three-dimensional sub-model is tracked by using an object tracking algorithm and according to the identified position information of the face in the first video image corresponding to the first three-dimensional sub-model, to obtain the position information of the face in the video image corresponding to each three-dimensional sub-model. Rotation angle information of the face in the video image corresponding to each three-dimensional sub-model is calculated according to the position information of the face in the video image corresponding to each three-dimensional sub-model, thereby determining the position information and the rotation angle information of the face in the video image corresponding to each three-dimensional sub-model.
The position information of each face is converted into position information in the three-dimensional space according to the position information and the rotation angle information of the face in the video image corresponding to each three-dimensional sub-model; then, by means such as rotation and zooming, each three-dimensional sub-model is converted into a three-dimensional sub-model adapted to the position information, of the face in the video image corresponding to each three-dimensional sub-model, in the three-dimensional space; and by using the video image corresponding to each three-dimensional sub-model as a background, each converted three-dimensional sub-model and the video image corresponding to the three-dimensional sub-model are synthesized into a three-dimensional model. By means such as rotation and zooming, each three-dimensional sub-model is converted into a three-dimensional sub-model adapted to the position information, of the face in the video image corresponding to each three-dimensional sub-model, in the three-dimensional space, so that the position of the converted three-dimensional sub-model in the three-dimensional model can be adjusted according to the position information, of the face in the video image corresponding to each three-dimensional sub-model, in the three-dimensional space. For example, when the three-dimensional sub-model is a three-dimensional model of a hat, the position of the hat can be dynamically adjusted according to the position information of the face.
205: Convert each generated three-dimensional model into a corresponding two-dimensional image, and use all two-dimensional images that are obtained through conversion as fused video images.
This embodiment does not specifically limit the manner of converting each generated three-dimensional model into a corresponding two-dimensional image. In specific implementation, the conversion manner includes, but is not limited to, converting each generated three-dimensional model into a corresponding two-dimensional image by using a perspective projection algorithm.
Because all the two-dimensional images are converted from the generated three-dimensional models, each three-dimensional model is generated according to each three-dimensional model file and each video image that are obtained through parsing, and each three-dimensional model file is obtained by parsing each three-dimensional image, each of the two-dimensional images obtained through conversion is already fused with a three-dimensional image, and therefore, all the two-dimensional images obtained through conversion can be used as fused video images.
Further, each three-dimensional image is separately fused with each video image by performing step 203 to step 205, to obtain fused video images. In order to obtain a processed video, the method provided by this embodiment further includes a subsequent step:
206: Synthesize the fused video images into a video, to obtain a processed video.
This embodiment does not specifically limit the manner of synthesizing the fused video images into a video either. In specific implementation, the fusing manner includes, but is not limited to, synthesizing the fused video images into a video by using a video codec, where the video codec may be an FFMPEG or the like.
Further, the processed video can be obtained by performing step 201 to step 206, where the processed video is a video having a watermark effect. Because one three-dimensional model file corresponds to one three-dimensional image, and one three-dimensional sub-model corresponds to one three-dimensional model file, one three-dimensional image corresponds to one three-dimensional sub-model. When one three-dimensional image is acquired, one three-dimensional sub-model is generated, and a video image corresponding to the three-dimensional sub-model is determined. No matter the three-dimensional sub-model corresponds to one video image or corresponds to at least two video images, because each video image corresponds to a same three-dimensional sub-model, the watermark effect of the obtained processed video is static. When at least two three-dimensional images are acquired, at least two three-dimensional sub-models are generated, and a video image corresponding to each three-dimensional sub-model is determined. No matter each three-dimensional sub-model corresponds to one video image or corresponds to at least two video images, there are at least two video images corresponding to different three-dimensional sub-models, and therefore, the watermark effect of the obtained processed video is dynamic, that is, the video processing method provided by this embodiment of the present invention not only can obtain a video having a static watermark effect but also can obtain a video having a dynamic watermark effect.
The method provided in this embodiment separately fuses each acquired three-dimensional image with each video image obtained by parsing an acquired to-be-processed video, and synthesizes fused video images into a video, to obtain a processed video, which implements adding a three-dimensional image to a video, and enables a processed video to display a three-dimensional image, thereby expanding an application range of video processing, and enriching display effects of the processed video.

In addition, the memory 120 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one magnetic disk storage device, a flash memory, or another volatile solid-state storage device. Accordingly, the memory 120 may further include a memory controller, so that the processor 180 and the input unit 130 access the memory 120.
The input unit 130 may be configured to receive input digit or character information, and generate a keyboard, mouse, joystick, optical, or track ball signal input related to the user setting and function control. Specifically, the input unit 130 may include a touch-sensitive surface 131 and another input device 132. The touch-sensitive surface 131, which may also be referred to as a touch screen or a touch panel, may collect a touch operation of a user on or near the touch-sensitive surface (such as an operation of a user on or near the touch-sensitive surface 131 by using any suitable object or accessory, such as a finger or a stylus), and drive a corresponding connection apparatus according to a preset program. Optionally, the touch-sensitive surface 131 may include two parts: a touch detection apparatus and a touch controller. The touch detection apparatus detects a touch position of the user, detects a signal generated by the touch operation, and transfers the signal to the touch controller. The touch controller receives the touch information from the touch detection apparatus, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 180. Moreover, the touch controller can receive and execute a command sent from the processor 180. In addition, the touch-sensitive surface 131 may be a resistive, capacitive, infrared, or surface acoustic wave type touch-sensitive surface. In addition to the touch-sensitive surface 131, the input unit 130 may further include the another input device 132.

Further, the touch-sensitive surface 131 may cover the display panel 141. After detecting a touch operation on or near the touch-sensitive surface 131, the touch-sensitive surface 131 transfers the touch operation to the processor 180, so as to determine the type of the touch event. Then, the processor 180 provides a corresponding visual output on the display panel 141 according to the type of the touch event. Although, in FIG. 9, the touch-sensitive surface 131 and the display panel 141 are used as two separate parts to implement input and output functions, in some embodiments, the touch-sensitive surface 131 and the display panel 141 may be integrated to implement the input and output functions.

The audio circuit 160 may convert received audio data into an electric signal and transmit the electric signal to the loudspeaker 161. The loudspeaker 161 converts the electric signal into a sound signal for output. On the other hand, the microphone 162 converts a collected sound signal into an electric signal. The audio circuit 160 receives the electric signal and converts the electric signal into audio data, and outputs the audio data to the processor 180 for processing. Then, the processor 180 sends the audio data to, for example, another terminal device by using the RF circuit 110, or outputs the audio data to the memory 120 for further processing. The audio circuit 160 may further include an earplug jack, so as to provide communication between a peripheral earphone and the terminal 900.
