Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] In order to solve the multi-track correlation problem in multi-target tracking, effectively solve the occlusion problem in the tracking process, and improve the accuracy and robustness of multi-target tracking, the embodiment of the present invention provides a multi-target tracking method under occlusion conditions, Referring to Figure 1, this method consists of two parts: a detection module and a target association module. Among them, the detection module is used to identify and locate the target, and the target association module is used to complete the multi-track association of the target. Firstly, the target detector based on block information [7] is used for target detection to obtain accurate target position information,...

Abstract

The invention discloses a multiple object tracking method. The multiple object tracking method comprises step 1, outputting the positional information of detected objects in every frame; step 2, executing step 5 when complete occlusion of a moving object occurs and calculating similarity values between interacted objects and executing step 3 or step 4 otherwise; step 3, associating corresponding objects in two consecutive frames directly when the similarity values meet the strong conditions simultaneously and finishing the process; step 4, solving the matching relation between the objects through an objective function and constraint conditions when the similarity values do not meet the strong conditions simultaneously and partial occlusion of the moving object occurs, associating the corresponding objects in the two consecutive frames according to the matching relation and finishing the process; step 5, monitoring a few continuous following frames of the current frame until the complete occlusion does not occur, recording a corresponding objective frame at present, calculating the similarity values between the objects, enabling the middle position between the current frame and the objective frame to serve as the position of a complete occlusion frame and finishing the process.

Description

technical field [0001] The invention relates to the field of target tracking, in particular to a multi-target tracking method. Background technique [0002] Multi-target tracking technology is one of the difficulties in computer vision research at present. With the rapid growth of computer data processing capabilities and the development of image analysis technology, this technology is very important in the fields of video surveillance, event analysis, and human-computer interaction. practical value. At the same time, in the military field, multi-target tracking has been used in unmanned reconnaissance aircraft battlefield reconnaissance, cruise missile terminal guidance, ballistic missile defense, ocean surveillance, battlefield surveillance, etc. Video-based multi-target tracking technology has become a popular research direction in the world. [0003] Multi-target tracking is to use the computer to automatically identify and locate the target in the video sequence, and ...
