Embodiment Construction

[0025] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0026] Such as figure 1 As shown, the intelligent video analysis personnel tracking method includes the following sub-steps:

[0027] S1: Content analysis: analyze the image content and eliminate useless background information, such as: static information such as ground and buildings, and dynamic information such as wind and grass, water waves, rain and snow, tree shadows, etc. can be judged as background information by intelligent video analysis , and important information is activity information such as people and vehicles.

[0028] S2: Object recognition: Accurately identify people, animals, vehicles or other objects according to the size, movement speed and movement law of different moving targets, and separate important information; ...

Abstract

The invention discloses a people tracking method based on intelligent video analysis. The people tracking method comprises the following steps of analyzing the content of an image, and removing unusable background information; according to the sizes, moving speeds and moving rules of different moving targets, accurately identifying people, animals, vehicles or other objects, and extracting important information; comparing the moving rule of each moving target and a formulated safety rule, and verifying the moving safety of each moving target; under a complicated background, positioning and tracking each moving target in real time; predicting and filtering the state parameters of each target, such as mass center displacement, speed and acceleration; after each target is blocked by a small blocking object, continuing to track; after the target tracking is completed, automatically returning back to a current preset position. The people tracking method based on the intelligent video analysis has the advantages that the multi-target tracking is realized, the continuous tracking on each target with blocking time not exceeding three seconds is realized, and the accurate tracking before crossing and after separation of multiple targets is realized.

Description

technical field [0001] The invention relates to a tracking method, in particular to a personnel tracking method based on intelligent video analysis. Background technique [0002] Security is an issue that all government departments, enterprises and institutions attach great importance to today. Video surveillance technology has become an effective means for public security organs to combat crime and terrorism. The video surveillance system has also begun to move towards large-scale construction. Currently, several Millions of surveillance cameras. These cameras are typically manned by busy security personnel and are used to monitor, store, or playback footage. Too many cameras make the on-duty staff tired and unable to exert real-time monitoring capabilities. This passive, post-mortem inspection method simply cannot provide a real-time security monitoring that meets today's needs. In this case, it increases the difficulty of solving crimes. , and wasted a lot of police for...
