Abstract

The present invention discloses a video analysis method and device. The method comprises: performing slicing process of video files, and obtaining video slices; distributing the video slices to a plurality of processors, performing decoding and analysis of distributed video slices by a plurality of processors through an analysis model; and integrating the analysis results of all the video slices. The video analysis method and device fully employ the advantage of parallel distributed calculation of processor and fully employ the calculation capability of each processor, so that the analysis speed is fast and the efficiency is high.

Description

technical field [0001] The invention relates to the field of video processing, in particular to a video analysis method and equipment. Background technique [0002] The current video analysis technology has been developed to use multiple central processing units (CPUs) to perform video analysis in a multi-threaded manner. Wherein, a video file is used as a unit to perform video analysis. In this way, although multiple CPUs perform data processing in a multi-threaded manner, for a video file, data processing is performed serially by multiple CPUs. Video files need to be fully decoded before they can be analyzed. [0003] Existing video analysis equipment is slow, inefficient and time-consuming. Contents of the invention [0004] In view of the above problems, the present invention is proposed to provide a video analysis method and device that at least partially solve the above problems. [0005] According to one aspect of the present invention, a video analysis method i...
