Embodiment Construction

[0035] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0036] At present, the application bottleneck of target detection and tracking lies in how to efficiently extract video information, and how to perform standard data exchange, interconnection and semantic interoperability with other information systems. To solve this problem, video structured description technology has been proposed. Through the use of video structured description technology to transform the traditional video surveillance s...

Abstract

The invention discloses a multi-target tracking method and a corresponding video analysis system for implementing the scheme. The method comprises the following steps: acquiring detection position information of a target; obtaining predicted position information of the target; matching the obtained prediction position information with the detection position information; updating the state information of the target based on the detection position of the target under the condition that the detection position information of the target is judged to be matched with the prediction position information of the target; under the condition that it is judged that the prediction position of a certain target has no detection position matched with the prediction position, judging that the target is an extinction target; and judging that the target is a new target or a reappeared target under the condition of judging that the detection position of a certain target is not matched with the detection position of the target. Therefore, through reasonable allocation of the functional modules, high tracking precision requirements can be met while low-computing-power high-speed tracking is realized.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a multi-target tracking method and a corresponding video analysis system. Background technique [0002] Object detection and tracking has been an important research direction in academia and industry. For example, the video surveillance system, as an important part of smart security and smart transportation in the application of the Internet of Things for the comprehensive management of urban public safety, is facing a huge challenge for in-depth application. Not only that, target detection and tracking also have huge practical space and potential significance in fields such as vehicle assisted driving, traffic and games. [0003] In recent years, with the rapid development of target detection algorithms and target attribute analysis algorithms, the accuracy of target detection and attribute analysis is getting higher and higher, but the amount of calculation is also increasing. ...
