Problems solved by technology

[0002] The foul monitoring device that detects moving objects in the related art has the following problems: (1) the background is misdetected as a moving object due to the existence of background noise in the video monitoring series of images; Slight jitter will misdetect the background 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 fouling monitoring device comprising (1) an image acquisition module which is used for acquiring video monitoring images; (2) an image preliminary processing module which is used for performing moving target preliminary detection processing on original video image sequence information and outputting effective video image sequence information including a moving target; (3) a filtering module which is used for receiving the effective video image sequence information and performing filtering processing on the background shape of the effective video image sequence information; (4) a background modeling module which is used for establishing a background model after filtering, wherein the background model is arranged to be composed of N shape context histograms which have weight and represent edge points; (5) a background subtraction module which is used for performing attributive classification on the edge points of a current frame of image and subtracting the edge points belonging to the background; and (6) a feature matching module. False detection of the moving target caused by background noise and camera jittering can be reduced to the largest extent and the real-time performance is great.

Description

technical field [0001] The invention relates to the field of sports competitions, in particular to a foul monitoring device. Background technique [0002] The foul monitoring device that detects moving objects in the related art has the following problems: (1) the background is misdetected as a moving object due to the existence of background noise in the video monitoring series of images; Slight jitter will cause the background to be mistakenly detected as a moving target; (3) In the process of detecting a 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 violation monitoring device, which can minimize the false detection of moving targets caused by background noise and camera shake, and has good real-time performance. [0004] The object of the present invention adopts following...
