Intelligent multi-target active tracking monitoring method and system

Abstract

The invention discloses an intelligent multi-target active tracking monitoring method and system. The method comprises a plurality of steps such as a multi-target active tracking step, an active focusing step, a target switching step, a relay tracking step, an access warning step and a complicated environment preprocessing step. A panoramic picture in a monitor region is acquired by virtue of a first camera, a tracked target is locked, real-time coordinate information of the tracked target in the panoramic picture as well as a first angle control value of a cradle head of a second camera corresponding to the coordinate information and a first focusing value of the second camera are calculated, when a close-up image of one tracked target needs to be acquired, the second camera positions the tracked target according to the angle control value and the first focusing value corresponding to the selected tracked target so as to acquire the close-up image, so that the second camera is always focused on the tracked target to continuously track and photograph the tracked target in real time. By adopting the intelligent multi-target active tracking monitoring method and system, the cradle head control problem and focusing problem in the video monitoring and multi-target tracking can be effectively solved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to an intelligent multi-target active tracking monitoring method and system. Background technique [0002] With the maturity and improvement of technologies such as computers, networks, communications, and streaming media, video is increasingly used in social production and life. In computer vision systems such as intelligent video surveillance, navigation, remote sensing, and license plate recognition, video is the most important source of information, and video surveillance is an important part of the security system. [0003] In a large-scale monitoring environment, the front-end equipment provides basic monitoring functions such as image acquisition and pan-tilt control. Users can watch real-time images on the monitor and track entities through pan-tilt control keyboard operations. In the current tracking and monitoring method, the management personnel manually control the rotat...
