[0031] Please refer to figure 2 , is a schematic diagram of functional modules of the multi-target tracking system 400 provided in the first embodiment of the present invention. The multi-target tracking system 400 can be applied to the above-mentioned user terminal 100, and is used to track multiple targets in a video frame to realize video monitoring, navigation, positioning, and the like. The multi-target tracking system 400 includes a tracking result acquisition module 410 , a target detection module 420 , a matching and association module 430 and a position determination module 440 .

[0032] The tracking result acquisition module 410 is used for filtering the previous frame image of the current frame image, so as to predict the position where the moving object in the previous frame image appears in the current frame image, and then obtain the tracking result.

[0033] In this embodiment, for the current frame image in the acquired video image, filter processing is perf...

Abstract

An embodiment of the invention provides a multi-target tracking method and system and relates to the technical field of image processing. The multi-target tracking method and system is characterized in that filtering is performed in the previous-frame image of a current-frame image to predict the position, appearing in the current-frame image, of a moving target in the previous-frame image so as to obtain a tracking result, moving target detection is performed on the current-frame image to obtain a detection result, the detection result is matched and associated with the tracking result to obtain an association result, and the positon of the moving target in the current-frame image is determined according to the association result. The multi-target tracking method and system is wide in application range, high in calculation efficiency, low in resource consumption and good in stability and high in accuracy during actual multi-target tracking.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a multi-target tracking method and system. Background technique [0002] Multi-object tracking is a research hotspot in the field of computer vision. Multi-target tracking refers to the use of a computer to determine the position, size and complete trajectory of each independent moving target of interest in a video sequence. In recent years, with the rapid growth of computer data processing capabilities and the development of image analysis technology, the real-time tracking technology of objects has come to the fore. Very important 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. [0003] The existing multi-target tracking method has high alg...
