Abstract

The invention provides a video generation method, a device, a device and a storage medium. The method comprises: obtaining an intermediate human face 3D model according to the target human face 3D model and a preset human face 3D model corresponding to the expression to be transformed, wherein the expression to be transformed is any one of a plurality of expressions; Extracting coordinates of keypoints in the intermediate human face 3D model; The coordinates of the key points include: a part of coordinates of a facial five-feature contour; The coordinates of key points of the target face 3D model are gradually adjusted to the coordinates of key points of the intermediate face 3D model according to a preset gradual change step size, and 2D images obtained after each adjustment are collected to obtain N 2D images, wherein N is an integer greater than 1; A video is generated from the N 2D images. The invention can realize the production of smooth video based on fewer static 2D diagrams,improves the production efficiency of the video, and can produce the expression change video of any static face.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video generation method, device, equipment and storage medium. Background technique [0002] With the development of terminal technology, more and more terminals are equipped with a video shooting function, and people can make moving pictures or short videos through the terminal. [0003] At present, the video production method is mainly to shoot through a camera, or continuously collect multiple frames of images through a camera, and then generate a video through manual processing. This method has high requirements on the quantity and quality of video frames. [0004] However, when the number of video frames captured by the camera is small, or there are gaps between video frames, it is difficult to produce smooth and high-quality videos. Contents of the invention [0005] The present invention provides a video generation method, device and storage medium, w...
