Embodiment Construction

[0029] Such as figure 1 As shown, the hardware system of the intrusion monitoring method of the present invention includes: a camera for collecting video images; a video codec for encoding and decoding processing and network transmission of images collected by the camera; a computer for receiving images from the video codec video images, and then use the intrusion monitoring method of the present invention to process the received video images.

[0030] Combine below image 3 The computer vision-based intrusion monitoring method of the present invention is described.

[0031] Firstly, the initial background model is established, that is, the video image is collected by the camera, the background image of N frames is collected, and the d-dimensional pixel value of each pixel point (i, j) in the image is obtained.

[0032] Then, use the N pixel values ​​of each pixel position to establish a non-parametric statistical model, which is expressed by a probability function:

Abstract

An invasion monitor method based on computer vision and used for the field of intelligent video monitor is disclosed; the invention in advance collects video images of a plurality of frames through a monitor camera in order to establish a scene model on the basis of non-parameter statistics. For the new video images, the scene model is used to detect prospect points, and a motion target is obtained by further processing the prospect points through morphologic filter. Afterwards, weighting histogram characteristics are extracted from the motion target and a histogram matching method is applied to tracing the motion target to obtain the motion track of the target. The method judges whether the target track enters into the set warning region in order to decide whether to sends the alarm. The invasion monitor method adopts the computer vision technology and realizes the automatic detection and alarming by utilizing the video information acquired by the computer process monitor camera, therefore the invention is simple in structure and convenient in implementing as well as has the extensive market prospect and application value.

Description

technical field [0001] The invention relates to an intrusion monitoring method, in particular to an intrusion monitoring method based on computer vision technology. Background technique [0002] The intrusion monitoring system refers to the system that uses the camera to judge the relationship between the target and the fixed area, such as judging the intrusion of the warning area and the erroneous entry of the dangerous area. At present, this type of system is mainly completed by security personnel observing the monitoring screen with naked eyes 24 hours a day. This is a very heavy work, and due to reasons such as fatigue, people's attention is easily distracted. Therefore, it will be very meaningful to use computers to process the video information returned by the camera to replace human monitoring. Contents of the invention [0003] The purpose of the present invention is to provide an intrusion monitoring method based on computer vision, so as to improve the shortcom...
