Video monitoring based public security image detection method

Abstract

The invention relates to a video monitoring based public security image detection method, and belongs to the technical field of image detection. The public security image detection method comprises the steps of firstly establishing a video monitoring point information database in allusion to all video monitoring points in a region, constructing a video monitoring topological graph according to data in the video monitoring point information database; secondly, extracting feature information of a detected target, recognizing the detected target, and carrying out analysis according to a result of detection recognition; and finally, pushing analysis result information of detection recognition to a command center. The invention provides an efficient and reasonable detection method in allusion to a target detection problem of a public security organization, thereby not only being capable of effectively utilizing existing video monitoring resources, greatly reducing input of the manual labor cost, and being capable of effectively improving the detection efficiency for the detected target at the same time.

Description

technical field [0001] The invention relates to a public security image detection method based on video monitoring, and belongs to the technical field of image detection. Background technique [0002] Public security organs are armed public security administrative and criminal law enforcement organs in the people's democratic dictatorship of our country. How to effectively improve the level of scientific and technological informationization and work efficiency of public security organs is of great significance. In recent years, with the rapid development of my country's economy and society and the continuous acceleration of the pace of scientific and technological informatization, my country's informatization level has made great progress; among them, video surveillance, as an important part of the social security system, has a particularly obvious development and growth trend . Therefore, it is of great significance whether the public security organs can effectively integra...
