Automatic tracking recognition system and method

Abstract

The invention provides an auto-tracking recognition system and a method. The system comprises a fixed viewing field camera, a suspicious object determination module, a trail tracking module, a control module, a variable viewing field camera, a picture recognition module, a contrast module and an alarm module, wherein, the suspicious object determination module is used for analyzing a video picture collected by the fixed viewing field camera, determining a suspicious object, and acquiring the position of the suspicious object; the trail tracking module is used for determining the motion trail of the suspicious object; the control module is used for outputting a control signal according to the position and the motion trail of the suspicious object; the variable viewing field camera is used for acquiring the video picture in accordance with the feature recognition requirement based on an adjustment parameter of the control signal; the picture recognition module is used for acquiring a feature parameter of the suspicious object; the contrast module is used for contrasting the acquired feature parameter with the feature information of the contrasted object in a feature database; and the alarm module is used for giving an alarm to the suspicious object in accordance with the set alarm condition. The invention can automatically track and collect detail pictures of the suspicious object, and efficiently realize the recognition of the suspicious object, thereby giving an early and reliable alarm.

Description

technical field [0001] The invention relates to the field of intelligent safety monitoring, in particular to an automatic tracking and identification system and method. Background technique [0002] With the development of human civilization, people's demand for security monitoring is getting higher and higher. The security monitoring system in the prior art usually uses a camera with a fixed field of view to collect video images within a fixed monitoring area, and cooperates with a computer to identify whether the target moving object violates the preset behavior rules, such as whether the target moving object has entered the warning Compared with the traditional safety monitoring mode of post-event investigation and processing, it has certain advantages and can achieve the purpose of prevention to a certain extent. [0003] However, the safety monitoring system in the prior art also has the following problems: [0004] Since the system uses a camera with a fixed field of...

Problems solved by technology

[0004] Since the system uses a camera with a fixed field of view, the collected video images are images of a fixed field of view. In many cases, it is difficult to collect clear detailed images of the characteristic parts of suspicious targets, making it difficult to identify suspicious targets;

[0005] It is impossible to determine the trajectory of suspicious targets, and it does not have the ability to automatically track
