Monitoring device for playground

Abstract

The invention provides a monitoring device for a playground. The monitoring device comprises the components of (1), an image acquiring module which is used for acquiring a video monitoring image; (2), an image preprocessing module which is used for performing moving object preliminary detecting on original video image sequence information and outputting effective video image sequence information that comprises a moving object; (3), a filtering module which is used for receiving the effective video image sequence information and filtering 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 module is composed of N shape context histograms which comprise weights and represent edge points; (5), a background subtraction module which is used for performing attribute classifying on the edge points on the current image frame and subtracting the edge points that belong to the background; and (6), a characteristic matching module. The monitoring device can maximally reduce moving object error detection caused by background noise and camera jitter, and furthermore has high real-time performance.

Description

technical field [0001] The invention relates to the field of intelligent monitoring, in particular to a monitoring device for sports fields. Background technique [0002] The video surveillance device that detects moving object 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 surveillance 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 monitoring device for sports fields, which can minimize false detection of moving objects caused by background noise and camera shake, and has good real-time performance. [0004] The object of the present in...
