A real-time multi-target tracking method in complex environment

Abstract

The invention discloses a multi-target real-time tracking method in a complex environment. The multi-target real-time tracking method comprises a first video acquisition module, a second video acquisition module, an information transmission module, a database, a background clipping module, a video processing module, a display module, a controller and an alarm module. According to the invention, the static background is cut out; video frame images of a large number of monitoring areas are collected; by integrating a large number of video frame images, the influence of figure activities and accidental events on background clipping is reduced, meanwhile, objects with a certain activity range appearing in a monitoring area are analyzed, and noise generated by the movable objects in the tracking process is reduced, so that the analysis difficulty is reduced, and the analysis and tracking accuracy is improved; in addition, the coordinate system is established for the global monitoring area,the coordinate point corresponding to the target is read, relay tracking is conducted on the target according to the coordinate where the target is located, the target is prevented from being lost inthe tracking process of the target, and relay cannot be completed in time.

Description

technical field [0001] The invention belongs to the technical field of video surveillance, and in particular relates to a multi-target real-time tracking method in a complex environment. Background technique [0002] With the progress of society and the development of cities, a large number of video surveillance systems are set up in both public and private areas. Video surveillance systems are an important means of mastering public security management. The establishment of video surveillance systems is of great significance for maintaining social stability. . [0003] The video surveillance technology in the traditional technology mainly plays the role of collecting, browsing and recording. For the monitoring field, manual viewing and judgment are required, and manual viewing and judgment require the staff to be in a state of high concentration for a long time. This is obviously difficult, so it has also spawned a large number of intelligent monitoring systems. The intelli...

[0003] The video surveillance technology in the traditional technology mainly plays the role of collecting, browsing and recording. For the monitoring field, manual inspection and judgment are required, and manual inspection and judgment require the staff to be in a state of high concentration for a long time. And this is obviously more difficult, so it has also spawned a large number of smart monitoring systems. The smart monitoring system mainly tracks and manages the target after the target is calibrated. When the target moves abnormally during the tracking process, an alarm is issued. It can be seen that no matter what kind of smart monitoring system, the tracking and monitoring of the target is a necessary technology, but in the existing technology, the smart tracking and monitoring technology still has its shortcomings. In a complex environment, the monitoring camera is easily and frequently blocked Blocked by the environment such as buildings, the monitoring camera cannot directly track the target, and it is easy to follow the wrong or lost track of the monitoring target. Moreover, in the actual monitoring environment, the environment itself is changeable, such as fallen leaves, Foregrounds such as insects and birds will bring troubles to the extraction of the background, thereby affecting the extraction of the background, and then affecting the tracking of the target. In order to solve this problem, the present invention provides the following technical solutions
