Embodiment Construction

[0052]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] The invention provides a video comparison method based on three-dimensional animation, such as figure 1 shown, including the following steps:

[0054] S101, read the video of the real person's movement, and divide the video into multiple pictures according to the frame rate;

[0055] Specifically, the video of the real action is taken in advance through the camera, which is used to render real objects in reality, and then the video can be read by a vide...

Abstract

The invention discloses a video contrast method, device and equipment based on three-dimensional animation and a storage medium. The video contrast method comprises the steps: reading a video of real person motion, and segmenting the video into a plurality of pictures according to a frame rate; additionally arranging a fixed virtual camera for a model in a unified engine, and extracting images of the virtual camera in real time in the motion process of the model; performing contour extraction processing on the segmented picture to obtain a first contour picture, and performing contour extraction processing on the picture extracted in real time to obtain a second contour picture; and matching the first contour picture with the second contour picture, finding out two contour pictures with high matching degree, and synchronously displaying the segmented pictures corresponding to the two contour pictures with high matching degree and the pictures extracted in real time. Therefore, real-time synchronization of the model animation and the video character actions can be realized, and the model animation can be compared with a real person video for viewing.

Description

technical field [0001] The invention relates to the field of video comparison, in particular to a video comparison method, device, equipment and storage medium based on three-dimensional animation. Background technique [0002] Model animation is generated by changing the position and rotation angle of each model in space during a period of time. The actions of the real people in the video are done in a real environment. Since the model animation is virtual, there will be some differences from the real action. In order to make people understand better, the live action video is needed as an auxiliary reference. [0003] At present, the playback of model animation is usually played by controlling the time axis of the model animation through the interface that comes with the engine. However, since the time axis is fixed, the animation of the model cannot be skipped. In addition, the timing of completing each part of the action in the real-life video does not match the timing ...
