Abstract

The invention provides a monitoring device for searching a moving object, and the device comprises (1), an image collection module which is used for collecting a video monitoring image; (2), an image initial processing module which is used for the initial detection processing of a moving object of original video image sequence information, and the outputting of effective video image sequence information comprising the moving object; (3), a filtering module which is used for receiving the effective video image sequence information and carrying out the filtering of the background shape of the effective video image sequence information; (4), a background modeling module which is used for building a background model after filtering, wherein the background model is set to consist of N shape context histograms which represent edge points and have weights; (5), a background reduction module which is used for carrying out the attribute classification of the edge points of a current image frame, and reducing the edge points belonging to the background; (6), a feature matching module. The device can reduce the wrong detection, caused by background noise and the jittering of a camera, of the moving object, and is good in instantaneity.

Description

technical field [0001] The invention relates to the field of intelligent monitoring, in particular to a monitoring device for finding a moving target. Background technique [0002] There are following problems in the monitoring device used to find moving targets in the related art: (1) the background is misdetected as a moving target due to the existence of background noise in the video monitoring series of images; (2) there are slight Jitter, the background will be misdetected as a moving target; (3) In the process of detecting the moving target, there are problems of large amount of calculation and poor real-time performance, so the moving target cannot be detected in time. Contents of the invention [0003] In view of the above problems, the present invention provides a monitoring device for finding moving targets, which can minimize the false detection of moving targets caused by background noise and camera shaking, and has good real-time performance. [0004] The obj...
