Abstract

The invention provides an automatic door which comprises an automatic door body and a video monitoring device mounted on the automatic door body. The video monitoring device comprises an image collecting module, an image initial processing module, a filtering module, a background modeling module, a background reducing module and a feature matching module. The image collecting module is used for collecting video monitor images. The image initial processing module is used for carrying out movement target initial detection on initial video image sequence information and outputting effective video image sequence information containing a movement target. The filtering module is used for receiving the effective video image sequence information and filtering the background shape of the effective video image sequence information. The background modeling module is used for establishing a filtered background model, the background model is composed of shape context histograms of N expression peripheral points with weights. The background reducing module is used for carrying out attribute classification on the peripheral points on the current frame of image and reducing the peripheral points belonging to the background. According to the automatic door, false detection on the movement target caused by background noise and vidicon shaking can be reduced to the maximum degree, and good real-time performance is achieved.

Description

technical field [0001] The invention relates to the field of intelligent access control, in particular to an automatic door. Background technique [0002] The video monitoring device in the related art has the following problems: (1) the background is misdetected as a moving target due to the existence of background noise in the video monitoring series of images; It is falsely detected 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 an automatic door. The video monitoring device in the device 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] An...
