Embodiment Construction

[0046] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0047] Such as figure 1 Shown, be a kind of online target tracking method based on multi-camera described in the present invention, specifically comprise the following steps:

[0048] Step 1: Obtain the image information and camera position information transmitted by all cameras, use the method of feature point matching to overlap area scenes, establish scene associations between different camera perspectives, and realize the synchronization of multiple camera information in overlapping areas;

[0049] Step 2: Generate a neighbor map measured by coordinates by recording the camera's setting position and overlapping area information, so that each camera has at least one neighbor camera;

[0050] Step 3: Each camera ...

Abstract

The present invention relates to an online target tracking method and system based on multiple cameras. The present invention combines a preset calibration synchronization scheme and a self-learning tracking method to solve the synergy and real-time problems between multiple cameras, and proposes corresponding method. The calibration synchronization scheme proposed by the present invention adopts the target projection matrix calculation method of feature point matching to synchronize the shared information of multiple cameras in the overlapping area; the self-learning tracking method proposed by the present invention records the performance model of the monitoring target and synchronizes it through the central server To detect and track the neighboring cameras to achieve the effect of conductive information synchronization.

Description

technical field [0001] The invention relates to an online target tracking method and system based on multiple cameras, belonging to the technical field of video analysis. Background technique [0002] With the application of video surveillance systems and the development of intelligent analysis technology, surveillance cameras and security video data are increasing day by day, making public security protection technology based on video analysis widely concerned by the society and the public, especially the video analysis method for multi-camera networks It is an urgent need in the field of public security. Therefore, through the multi-camera-based target tracking method, trajectory clues for auxiliary event recognition and analysis can be generated, providing effective event clues for analyzing specific targets such as people, vehicles, objects, and regional security status, and improving the accuracy of event mining and recognition . [0003] Multi-camera target tracking ...
