Image frame retrieval, filtering and monitoring system based on video identification technology

Abstract

The invention discloses an image frame retrieval, filtering and monitoring system based on the video identification technology, the operation of the system is monitored, and video sources are generated. The operation steps for each received frame of video monitoring frame according to the time sequence include: (1) performing background modeling for a current video monitoring frame, obtaining existed moving targets in the current video monitoring frame, detecting position data of each target, and continuing step (1) if the target is not detected; (2) identifying the detected targets, obtaining identification information of each target, printing the identification information on a warning box frame image, and saving the information in a configuration file; and (3) reading the configuration file when a monitoring video is played, and making the time satisfying the condition flash in a highlighted manner on the timeline according to a retrieval condition input by a user. According to the system, filtering and rapid retrieval of monitoring videos can be effectively realized, key target information in the videos is identified, key moments in the videos are rapidly located, and the pressure for video storage and transmission is reduced.

Description

technical field [0001] The invention relates to an image frame retrieval filtering monitoring system based on video recognition technology, and belongs to the technical field of monitoring video image processing. Background technique [0002] With the continuous deepening of the construction of "harmonious society" and "safe city", the upgrading of video security monitoring technology, the change of new technology and the future development have received more and more attention from all walks of life. Technologies such as high-definition video, video storage, and intelligent video analysis have become the main aspects of the current video technology development. 2011 is a year of rapid development of my country's security industry. In addition to the increase in market demand, the government has vigorously promoted, especially the completion and use of the construction and use of the urban alarm and monitoring system ("3111" project), and the Universiade and other large-scal...

Problems solved by technology

[0006] However, how to effectively integrate and utilize green mirror retrieval technology in the field of video surveillance needs further research and development. Now some patents have been involved in this technical field, but there are certain deficiencies. For example, for video retrieval technology based on key frames, Although the key target frame of a video can be obtained now, it is usually impossible to identify what the target in the video is, which type it belongs to, and does not filter the noise of the video target, etc.
