Abstract

The invention discloses a border-crossing detection method and a border-crossing monitoring system based on video monitoring. The border-crossing detection method comprises the following steps: obtaining a closed boundary line and a safe passage line according to an endpoint of the top safe passage line of a boundary line set by a user; obtaining a tracking region through expansion and reduction of the closed boundary line; detecting a moving object of each frame of video monitoring image, to screen out a moving object region in the tracking region; performing matching tracking on the screened moving object region and a tracking object, to obtain a coordinate queue of the tracking object; performing object behavior analysis on the tracking object; judging whether a border-crossing risk exists; if no border-crossing risk exists, doing nothing; if a great border-crossing risk exists, warning; otherwise, judging whether an early warning for the current abnormal situation is required according to a security identifier; when warning or early warning, marking a target track according to the target coordinate queue. According to the invention, the border-crossing detection is performed according to the set boundary, the border-crossing detection for large regions and complex sites can be implemented, and the scope of application is wide.

Description

technical field [0001] The invention belongs to the technical field of computer vision, and more specifically relates to a video monitoring-based cross-border detection method and a border-crossing monitoring system. Background technique [0002] As one of the main means of modern security, intelligent video surveillance has a very good development prospect. Among them, cross-border detection is an important aspect of intelligent video surveillance. [0003] The current popular cross-border detection is mainly realized by infrared through-beam sensors, laser reflection sensors and other tools. Infrared through-beam sensors use infrared rays from the human body to detect current changes with high accuracy, but are easily interfered by strong sunlight and other light sources containing infrared rays. The laser reflection sensor determines the distance of the measured object by emitting a laser beam and receiving the reflected wave of the laser beam. It has high precision and...
