Problems solved by technology

[0002] Most of the current monitoring systems have integrated intelligent analysis functions, but the results of intelligent analysis are usually used for video control or early warning, but not saved
Some systems provide a dedicated database to save and retrieve intelligent analysis results, but this makes the complex monitoring system even larger and difficult to maintain, and file content retrieval must rely on the database, which has limited flexibility and versatility

Embodiment Construction

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] In traditional video surveillance situations, when it is necessary to view historical video files, it often requires a lot of manpower and time to browse a large number of video files. Although there are various monitoring occasions, the monitoring scene is usually fixed; the content of interest is fixed. For example, in traffic monitoring, we usually only care about the movement of vehicles and pedestrians, whether there are violations, traffic flow, and so on. Based on these characteristics, in this example, the video intelligent analysis and MPEG-7 are comprehensively applied to the video surveillance of fixed occasions.

[0039] 1. Video file storage framework

[0040] The program flow of the video file storage part is as follows figure 1 : After the real-time video data is obtained from the surveillance camera, it is sent to the int...

Abstract

Information storage / retrival method of video files based on MPEG-7 in monitoring system, wherein, 1) video files information storage step includes: obtaining video data; analyzing the obtained video data and proceeding video files storage at the same time; when a video file is stored, a standard text description file for recording information of mobile in the video is generated at the same time; 2) video files information retrival step includes: guiding aoo the description files into searcher, searching according to defined searching condition; locating to corresponding video file according to the result. The method combines MPEG-7 with intelligent video monitoring system so that monitoring video files can be retrieved and located conveniently, quickly and accurately. The invention has high accuracy and fast retruval speed, and provides effective solution for information organization and retrival of mass files in monitoring system, high-speed retrival of monitoring video content is possible.

Description

Background technique [0001] Intelligent video surveillance is an emerging application direction and a subject of much concern in the field of computer vision. The intelligent video surveillance system uses the powerful data processing function of the computer to automatically analyze the video data stream with the support of the algorithm without human intervention, so as to realize the segmentation, classification and tracking of the moving objects in the dynamic scene. On this basis, it completes the function of behavioral analysis of moving targets and early warning of abnormal behaviors. [0002] Most of the current monitoring systems have integrated intelligent analysis functions, but the results of intelligent analysis are usually used for video control or early warning, but are not saved. Some systems provide a special database to save and retrieve intelligent analysis results, but this makes the already complex monitoring system more complex and difficult to maintain,...
