Abstract

The invention provides a DirectShow-based moving object detection method, which comprises the following steps of firstly, based on a Gaussian mixture background modeling method, preprocessing a videoimage to obtain a background pixel model; based on a background difference method of OpenCV and a target tracking algorithm, solving through a video frame image and a background pixel model to obtaina moving target local image; and finally, acquiring the position parameters of the moving target based on a moving target positioning algorithm. The invention also provides a DirectShow-based moving object detection module and a monitoring system. According to the invention, 1) the data of a plurality of video images can be captured, converted and rendered at the same time, so that the utliziationrate and the video monitoring range of the monitoring system are improved; furthermore, by adopting a DirectShow-based moving target detection method, the video capture can be quickly and accuratelyrealized, the effectiveness of the monitoring system is accurately ensured, and the time is saved for data processing.

Description

technical field [0001] The invention belongs to the field of intelligent monitoring, and in particular relates to a moving target detection method based on DirectShow, a moving target detection module and a monitoring system. Background technique [0002] With the development and provision of computer vision recognition technology, intelligent monitoring systems are tending to replace traditional video surveillance devices. Intelligent monitoring systems turn post-event analysis into real-time analysis and early warning, reducing the burden on personnel and reducing the probability of accident development . Among them, moving target detection is an important part of intelligent monitoring, and many moving target detection methods have been proposed and adopted. From the security monitoring of ordinary communities and important places to the traffic monitoring of cities and highways, from the detection and tracking of military targets to smart weapons, video surveillance sys...
