Problems solved by technology

[0003] However, at this stage, the management generally adopts manual supervision for management. The management effect is affected by factors such as light, time, and weather, and cannot achieve satisfactory results. Problems such as workload and bloated positions have increased the cost of the management
However, there is no device and method capable of intelligently detecting defecating behavior at home and abroad, and it still cannot completely solve the above problems.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing:

[0022] Such as figure 1 In the shown working flow diagram of the inventive method, the steps of the detection method of the present invention are as follows:

[0023] (1) Install monitoring cameras and alarm equipment in areas where defecation and defecation occur frequently, such as the ground and corners. The camera lens can monitor the ground and corner areas in real time; the cameras and alarm equipment are connected to PC equipment through data lines to form a monitoring system;

[0024] (2) The monitoring system processes the images captured by the camera at a sampling frequency of 3 frames per second, and performs Gaussian filtering on the images;

[0025] (3) The system uses the first 30 seconds of images to train a basic background model, uses this background model to separate the foreground from the background, and then periodically updates the learned background...

Abstract

Disclosed is an anywhere defecation behavior monitoring method based on machine vision. The method can make video recording and warning for an anywhere defecation behavior at a corner. A system acquires an image by the aid of an existing surveillance camera, a body silhouette is denoised and extracted from the image by the aid of a background segmentation technique, body motion characteristics are extracted by the aid of image subtraction operation, a motionless state or a motion state of a human body is judged, the human body in the motionless state for five seconds is regarded as an anywhere defecation person, and the system issues warning voice to repel the anywhere defecation person. The method does not need manual supervision, labor cost and economic cost are greatly saved, and the uncivilized anywhere defecation behavior is effectively governed.

Description

technical field [0001] The invention relates to the field of image analysis and recognition, in particular to a method for monitoring and alarming changes in human body images by using machine vision. Background technique [0002] With the improvement of the level of science and technology and culture, the quality of our country's citizens has also gradually improved. However, there are still uncivilized behaviors of people defecating at will in the backside of remote public places or in dark and backlit corners. Even if the warning signs of "It is strictly forbidden to defecate here" are posted, it cannot effectively prevent the occurrence of open defecation. This kind of problem is a headache for the facilities management. At the same time, uncivilized behaviors such as defecation indiscriminately also damage the image of the city and humanity. In addition, the behavior of defecating in places will also cause environmental pollution, leading to the birth and accumulation...
