Problems solved by technology

[0002] The traditional solid and hazardous waste storage detection is mainly through the combination of video monitoring and infrared monitoring. Its main feature is that the staff need to monitor the monitoring screen by staring at the screen, otherwise it is necessary to go back after an environmental accident. Surveillance video to find clues, can not prevent the occurrence of environmental accidents
At the same time, due to the huge number of monitoring points, it is impossible for limited monitoring personnel and display devices to pay attention to all monitoring points at the same time. Most of them adopt the method of polling and playing. In most cases, the video images of the monitoring points are not seen by the monitoring personnel. , it is likely that there will be noteworthy anomalies within these times
And because the monitoring personnel did not discover it on the spot, they missed the opportunity to deal with it in time
In addition, the monitoring personnel cannot concentrate for a long time. Faced with so many monitoring images, they often miss the opportunity to eliminate the accident in the bud due to a negligence of the monitoring personnel.

[0030] In order to facilitate the explanation of the problem, the following symbol system is agreed:

[0031] F(x,y)-----The pixel value at the current video image (x,y) is F(x,y);

[0032] B(x,y)------The pixel value at the background image (x,y) is B(x,y);

[0033] S(x,y)------binary foreground, obtained by binarizing the difference between the background image and the current video image;

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as figure 1 Shown, the present invention comprises the following steps:

[0036] (1) Remains detection

[0037] Note: All images processed here are 8-bit grayscale images, and the range of grayscale values ​​is 0-255.

[0038]The traditional method of relic detection is to establish two backgrounds with different background update rates through an appropriate background modeling method (sliding average background modeling, codebook backgr...

Abstract

The invention discloses a method for determining storage states of solid waste and hazardous waste by using video analysis. The method comprises the following steps: analyzing a video of a solid waste and hazardous waste storage site in real time, once abandoned materials are stored outside the stacking area, comparing the abandoned materials with the hazardous waste in the stacking area to generate alarm information, and carrying out intervention on the abnormity through workers; detecting hazardous waste transfer behaviors in the stacking area, once a transfer behavior occurs, recording the transfer time and immediately giving a transfer signal so that the monitoring personnel can check and monitor the transfer behavior; and carrying out boundary detection on the stacking area, and once the stacking crosses the boundary, generating a boundary crossing signal to prompt that the hazardous waste needs to be transferred.
