Method and device for generating video abstract

Abstract

An embodiment of the invention provides a method and a device for generating a video abstract, wherein the method for generating the video abstract comprises the steps of acquiring a target searchingcondition, performing searching in an established database, and obtaining a first track set which comprises all tracks that accord with a target searching condition; according to overlapping state information, dividing at least two overlapped tracks in a first track set to one set, and defining each set as a combined track; performing translation of the tracks which satisfies a preset translationcondition to the same target time segment along a time axis; acquiring all first target original picture which correspond with all tracks in the target time segment from the database; acquiring a first abstract background picture which is used for generating a video abstract; and splicing all first target original pictures with the first abstract background picture, thereby generating a video abstract. The method and the device can improve the visual effect of the video abstract which is generated on the condition of complicated target tracks.

Description

Technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for generating video abstracts. Background technique [0002] With the continuous improvement of video data processing requirements and the increasing volume of video data, users hope to create a summary for a long video, and quickly browse in order to make better use of the video, for example, to maintain public order and combat Video surveillance of illegal and criminal phenomena. Therefore, video abstract technology came into being. Video summary technology is to analyze the structure and content of the video, extract the meaningful part from the original video, namely the moving target, and combine the moving target with the background scene in a specific way to form a concise and fully express video content The summary of the video; the video summary is a simple summary of the long video content, usually represented by a static or dynamic im...

[0004] However, when the trajectories of the target objects are arranged, the actual situation is complicated, and there are situations where the trajectories of multiple target objects overlap. Since the above-mentioned technology rearranges the trajectories of the target objects, the overlapping trajectories of the target objects are arranged. Therefore, when the trajectories of multiple target objects overlap, the summary video will lose the information of the associated target object; and due to the loss of the associated target object information, a target object will appear frequently in the generated video summary. and disappearing phenomena, resulting in poor visual effects
