An Active Tracking Method Based on Video Image Dynamic Monitoring

Abstract

The invention discloses an active tracking method based on dynamic monitoring of video images, and relates to the field of image recognition. The specific steps include the following steps: collecting video images; judging face information in dynamic images; The dynamic changes of the panoramic image can be trained to obtain multiple feature image information of dynamic objects; the feature image information is compared, the marked person is identified and determined, and the focal length parameters of the marked person image are recorded; a virtual two-dimensional plane is constructed, and the marked person is output on the regional map The actual coordinate point on the map; output the actual movement trajectory of the marked person within the monitoring range of the device; output the actual movement trajectory of the marked person within the monitoring range of the adjacent device; generate the path of the marked person on the monitoring area map. The invention can monitor and identify no dead angle in the monitoring area, reduce the calculation amount of tracking and identification, make campus monitoring and tracking change from passive to active, and improve the reliability and safety of campus security.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to an active tracking method based on dynamic monitoring of video images. Background technique [0002] Campus security is an important part of strengthening school safety management. It is the guarantee for the normal development of education, teaching and life order in the school. It is also an effective way to effectively solve the problem of campus safety. The existing security generally uses cameras in the campus for manual supervision, which leads to a large workload of supervision, and it is easy to cause insufficient monitoring, and it is impossible to detect and track non-campus personnel in time. It is often used to retrieve video footage after a campus safety accident occurs. Viewed in a very passive way. The existing positioning and tracking systems are generally realized by GPS positioning, that is to say, the tracked person must have a device tha...

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings that the existing mature tracking system cannot be used to track non-campus personnel in real time, resulting in the campus security being very passive in terms of monitoring and real-time tracking. At the same time, there will be a large amount of calculation for video image recognition, and The existing video image acquisition direction is fixed, and there is a dead angle of video image acquisition, but an active tracking method based on video image dynamic monitoring is proposed
