Embodiment Construction

[0040] The invention relates to a multi-target tracking method in an intelligent video monitoring system, which is a moving target tracking technology under the condition of a fixed camera.

[0041] A multi-target tracking method in an intelligent video surveillance system, comprising the following technical features:

[0042] 1. Extract a stable and comprehensive traditional color space (color based) feature and a composite feature based on contrast (contrast based) feature for target matching for the detected target;

[0043] 2. On the premise of weak detection, in order to solve the problem of tracking loss, a tracking queue based on multi-generational targets is created; the multi-generations in the tracking queue of multi-generational targets endow each tracking object with a corresponding life according to the result of each tracking divided by quality. Multi-generation tracking queues are divided into temporary tracking queues, stable tracking queues, and tracking loss...

Abstract

The invention discloses a multi-target tracking method in an intelligent video monitoring system, and relates to the technology of intelligent video information processing. The method comprises the following steps of: acquiring video data, pre-processing video images, and partitioning targets; and then extracting comprehensive characteristic information combining stable traditional color-based characteristics and contrast-based characteristics for target matching, establishing a multi-generation tracking queue for the tracked targets, implementing alteration of the multi-generation tracking queue by adopting a life quality competition mechanism, and finally implementing reliable target tracking. The method ensures accurate and reliable multi-target tracking results in intelligent video monitoring, meets the multi-target monitoring requirements in specific environments such as highways and the like, and lays a foundation for application research of the intelligent video monitoring.

Description

technical field [0001] The invention belongs to the technical field of intelligent video information processing, and in particular relates to a multi-target tracking method in an intelligent video monitoring system. Background technique [0002] With the development of multimedia technology and the rapid improvement of computer performance, intelligent video surveillance systems are more and more widely used in various scenarios. At present, a large amount of research work on automatic video surveillance has been carried out in the United States, Europe, and Japan, and video surveillance has also become an important topic of discussion in recent international conferences and working groups. Domestic related research has also been carried out. [0003] Video surveillance technology is to observe the moving targets in the monitored scene in real time, such as people or vehicles, and analyze their behavior, which involves computer vision, pattern recognition, artificial intell...
