Video splicing method and device, electronic equipment and computer storage medium

Abstract

The invention relates to the field of video processing, and discloses a video stitching method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: detecting the similarity between a first image and a second image, wherein the first image is the last frame of image of a first to-be-stitched video, and the second image is the first frame of image of a second to-be-stitched video; then, if the similarity meets a preset condition, determining a motion vector of the first image relative to the second image; according to the motion vector, determining at least one compensation frame between the first image and the second image, and splicing the first image and the second image based on at least one compensation frame so as to splice the first to-be-spliced video and the second to-be-spliced video. According to the method provided by the embodiment of the invention, the smooth compensation can be efficiently carried out on jitter occurring at the joint in real time, so smooth transition can be carried out among multiple video segments, and the occurrence of image jitter or image hopping after the multiple video segments are splicedis effectively reduced.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular, the present application relates to a video splicing method, device, electronic equipment and computer storage medium. Background technique [0002] With the reduction of traffic charges, the cost for users to publish the videos taken is also reduced, so many users upload the videos they take to the corresponding video platforms. If the user is shooting non-linear video, that is, multiple video clips with similar front and rear views are shot at the same location, and only the shooting time is different, then after the shooting is completed, the multiple video clips with similar front and rear views will be uploaded to the corresponding In front of the video platform, the multiple video clips are often spliced, and then the spliced ​​video is uploaded to the corresponding video platform. [0003] However, when splicing two video clips with similar framing, the po...

[0003] However, when splicing two video clips with similar views, the position of the photographer's smart terminal may change slightly, resulting in shaking at the junction of the two videos, which greatly reduces the user's viewing experience

[0004] Traditional video splicing is often based on the method of video frame interpolation. For example, 30FPS (Frames Per Second, frames per second) video is generated by frame interpolation compensation to generate 60FPS video, and it is mainly used for frame interpolation within a single video content. However, for non-linear video shooting, when splicing two videos, due to the uncertainty of the relationship between the front and back frames, the conditions for frame insertion cannot be fully satisfied.

In addition, the traditional video frame insertion method usually has a relatively large amount of calculation and a relatively long running time, and its usage scenarios are biased towards traditional video post-processing; if it is applied to the mobile device, the hardware in the mobile device must be able to support it. function, but currently only a very small number of hardware manufacturers support such functions, and the algorithm is relatively fixed, resulting in more restrictions on mobile devices and usage scenarios

In addition, even if the traditional video frame insertion method is applied to the mobile device, it will be difficult to achieve real-time processing due to the limited computing power of the mobile device, resulting in poor real-time performance and the need for users to wait.
