Video cutting method and device, terminal equipment and readable storage medium

Abstract

The invention provides a video cutting method and device, terminal equipment and a readable storage medium. The method comprises the following steps: acquiring a cutting frame corresponding to each frame of picture of a to-be-cut video, then grouping the cutting frames according to a preset number and a time sequence of each frame of picture to obtain a plurality of groups of cutting frames, then rejecting abnormal cutting frames in each group of cutting frames, performing mean value calculation on each group of cutting frames after the abnormal cutting frames are rejected to obtain a cutting frame of a first frame of picture in a plurality of frames of pictures corresponding to each group of cutting frames according to the plurality of groups of cutting frames, performing difference calculation on the cutting frame of each frame of picture between the first frames of pictures in two adjacent groups according to the cutting frame of the first frame of picture in each group to obtain the cutting frame of each frame of picture between the first frames of pictures in the two adjacent groups, and finally, according to the cutting frame of each frame of picture, cutting the to-be-cut video. According to the method, the problem of video jittering caused by sudden change of the cutting frames of continuous multi-frame pictures can be avoided.

Description

Technical field [0001] The present invention relates to the field of data processing, and more particularly to a video cutting method, apparatus, terminal device, and a readable storage medium. Background technique [0002] The video frame of the partial area is intercepted in the video to form a new video of the traffic scene. The crop frame for each frame is required and then extract the contents of the crop frame to resie the new video. However, since the crop frame is independent of each frame, there will be a calculated crop frame for a while, and the problem under the next will, eventually leading to the synthetic video, and the video quality is extremely poor. Inventive content [0003] An object of the embodiment of the present invention is to provide a video cutting method, device, terminal device, and readable storage medium that packets the crop frame, and calculates each group. The crop frame is calculated between the cropper cutting frame after eliminating the abnor...

AI Technical Summary

Problems solved by technology

However, since the cropping frame is calculated independently for each frame, there will be problems that the calculated cropping frame will be larger and smaller for a while, and will go up and down for a while, which will eventually lead to jitter in the synthesized video, and the video quality is extremely poor
