[0004] However, the existing summary video generation method can only generate the corresponding summary video for the video collected by a video capture device.
However, in practical applications, for a video capture device, the scene angle of the captured video is limited, the moving target information contained in it is relatively small, and the user experience is poor.

The embodiment of the invention provides a summary video generation method and a generation device. The method comprises steps: for at least two original videos, acquisition scene images of the at least two original videos are merged to obtain a target scene image; for each original video, the first video information of each first motion target contained in the original video is extracted; the same second motion target contained in the at least two original videos is recognized, the first video information of each second motion target in the at least two original videos is merged, and the second video information of each second motion target is obtained; positions of each first motion target and each second motion target at each moment in the target scene image are determined; and each first motion target and each second motion target are sequentially displayed in the target scene image, and a summary video is generated. The embodiment can generate one summary video for videos acquired by multiple video acquisition devices, and the user experience is improved.
Description
technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for generating abstract video. Background technique [0002] With the development of video technology, summarizing video plays an increasingly important role in video analysis and content-based video retrieval. For example, in the field of social public security, the video surveillance system has become an important part of maintaining social order and strengthening social management. However, video recording has the characteristics of large amount of stored data and long storage time. The traditional method of finding clues and obtaining evidence through video recording consumes a lot of manpower, material resources and time, and the efficiency is extremely low, so that the best time to solve the case is missed. [0003] The existing abstract video generation method can extract all the moving objects through moving target analysis on the vid...
