Embodiment Construction

[0076] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0077] Video structuring is a technology for extracting video content information. It uses time-space segmentation, feature extraction, object recognition and other processing methods to organize video content into text information that can be understood by computers and humans according to the semantic relationship. In the prior art, video structural analysis is performed frame by frame for each video frame in the video to be analyzed, and the efficiency of vi...

Abstract

The embodiment of the invention provides a video structured analysis method and device, and is applied to the technical field of video analysis, and the video structured analysis method comprises thesteps: obtaining to-be-analyzed video data; for a to-be-detected video frame in the video data, determining whether the to-be-detected video frame contains a concerned target main body or not througha preset algorithm; and if the to-be-detected video frame contains the target main body, performing video structuralization analysis on the to-be-detected video frame. According to the video structured analysis method, the video structural analysis is carried out on the to-be-detected video frame containing the target main body, so that the speed of carrying out the video structural analysis on the video data can be increased, and the efficiency of the video structural analysis is improved.

Description

technical field [0001] The invention relates to the technical field of video analysis, in particular to a video structured analysis method and device. Background technique [0002] As an important source of IoT visual perception, video data is playing an increasingly important role in the field of public safety. Video structured analysis is an in-depth application of unstructured video data, making video data a perceivable and descriptive intelligent data with a wide range of applications. For public security, video structured analysis has penetrated into almost all aspects of public security. Through video structured analysis of video data captured by surveillance in public places, corresponding data can be extracted. [0003] In related video structural analysis methods, a common practice is to analyze each video frame in the video to be analyzed frame by frame, so as to complete the video structural analysis of the video to be analyzed. The existing video analysis metho...
