Video monitoring device capable of detecting moving object

Abstract

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

Description

technical field [0001] The invention relates to the field of intelligent monitoring, in particular to a video monitoring device capable of detecting moving objects. 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 video monitoring device capable of detecting moving objects, which can minimize false detection of moving objects caused by background noise and camera shake, and has good real-time per...
