A traffic video monitoring system based on standard labeling and quick search

Abstract

The present invention discloses a traffic video monitoring system based on standard labeling and quick search, comprising a traffic monitoring video capturing module, a video image content analyzing module, a traffic video key frame obtaining module, a monitoring expansion data encoding module and a data stream searching module. Based on an SVAC standard, the grammar and semantics of the monitor messages can be appropriately expanded to satisfy the requirements of quick search of monitoring videos. The system provides a unified standard interface to realize labeling and quick search of compressed monitoring video data, and the monitor messages can be appropriately stretched and clipped according to business requirement to meet demand of functions such as data transmission. Meanwhile, an encoding scheme targeting traffic objects and events is worked out and the SVAC standard is used to realize a highly-accurate, simple, effective, unified and fast labeling and quick search method of traffic objects and events.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and relates to a traffic video monitoring system, in particular to a traffic video monitoring system based on standard marking and fast retrieval. Background technique [0002] SVAC: the abbreviation of Technical Specification of Surveillance Video and Audio Coding in English, corresponding to "Technical Requirements for Digital Video and Audio Coding for Security and Surveillance Monitoring" in Chinese, which was established by the First Research Institute of the Ministry of Public Security and the National Security and Alarm System Standardization Technical Committee (SAC / TC100) After combing and analyzing, the main similarities and differences between the video and audio coding and decoding of security monitoring and broadcasting media were sorted out, and the special requirements of digital video and audio coding and decoding of security monitoring were clarified. After repeated discu...

AI Technical Summary

Problems solved by technology

The use of the SVAC standard is completely aimed at the video surveillance network, which can solve the problem that the system is difficult to interconnect and interoperate caused by the inconsistency of video and audio codec standards in the current video surveillance system. This interoperability solution provides a unified standard interface to achieve compression Marking and fast retrieval of surveillance video data, and proper scaling and cutting of surveillance information according to business needs to meet the needs of transmission and other functions. At the same time, a set of coding schemes for traffic objects and events is formulated, and finally the SVAC standard is used To realize a high-accuracy, simple, effective, unified and fast marking and fast retrieval method of traffic objects and traffic events, the technical solution is:
