Regional invasion real-time detection method

Abstract

The invention relates to a regional invasion real-time detection method, which comprises the following steps: (1) establishing a monitoring scene according to video frame data and updating the monitoring scene in real time; (2) obtaining a moving target by using a movement detection algorithm; (3) tracking the moving target by using a target tracking algorithm and obtaining position coordinates of the moving target; and (4) performing invasion judgment on the moving target by using a region detection algorithm, namely, performing full-region shielding processing on a full region in the monitoring scene, classifying and marking a shielded region and a warning region, acquiring sensitive parameters of the state of the warning region and taking the sensitive parameters of the state of a regional space position where the moving target is as target invasion judgment bases to realize regional invasion real-time detection. The method has the advantages of rational design, realization of a regional invasion real-time detection function by using a region classifying and marking method, simple concept, easy implementation, improvement on processing speed and execution efficiency and adaptability to the real-time monitoring of regions of any polygonal shape (convex and concave polygons).

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a real-time area intrusion detection method. Background technique [0002] With the continuous development of intelligent monitoring technology and the increasing maturity of image processing technology, the method of artificially monitoring suspicious objects has been far from meeting the actual needs. At present, intelligent security systems based on technologies such as artificial intelligence and video analysis make up for the shortcomings of manual methods to a certain extent. The advantage of the intelligent security system is that the security personnel do not need to patrol the site, they can obtain the actual situation of the site through the video returned by the monitoring system, and can quickly make decisions, so there is a broad development space and a huge potential market. Existing area detection methods mainly use warning area intrusion detection, regional people...

AI Technical Summary

Problems solved by technology

The above-mentioned area detection methods are generally realized based on the complex judgment between the moving target and the warning area. Even for a simple rectangular area, a large number of judgments are required. The existing problems are: these methods have a large amount of calculation and complex thinking , especially for areas like concave polygons, the efficiency is low
