Problems solved by technology

[0002] The guidance system for tracking a moving target in the related art has the following problems: (1) the background is misdetected as a moving target due to the presence of background noise in the video surveillance series of images; 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

Abstract

The invention provides a guide system, and the system 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; (7), a guide module. The system 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 guidance, in particular to a guidance system. Background technique [0002] The guidance system for tracking moving objects in the related art has the following problems: (1) the background is misdetected as a moving object due to the presence of background noise in the video surveillance series of images; 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 guidance system, which can minimize the false detection of moving objects caused by background noise and camera shaking, and has good real-time performance. [0004] The object of the present invention adopts following technical scheme to realize: [0005] A boot system i...
