Embodiment Construction

[0055] The specific implementation and effects of the present invention will be described and shown below in conjunction with the technical solutions and drawings.

[0056] Due to the lack of video-based sewage discharge detection methods, there is currently no unified video database to test and evaluate various methods, and sewage discharge videos are relatively sensitive, and it is difficult for ordinary people to obtain video data. In order to verify the effectiveness of this method, by simulating the water body discharge process, a video, namely Video 1, was shot, and another video, namely Video 2, was obtained on the Internet to test this method.

[0057] According to the basic flow chart of the specific implementation of the technical solution, first convert the video frame to HSV space, and calculate its cleanliness according to the saturation and brightness components, then perform median filtering to smooth the noise, and then calculate the cumulative difference map of...

Abstract

The invention belongs to the technical field of video detection, and in particular relates to a sewage discharge detection method based on HSV color space. A sewage discharge detection method based on HSV color space, step 1: convert the video frame to HSV space, and obtain a three-dimensional image matrix, corresponding to the hue, saturation, and brightness components; step 2: use a 3x3 template to check the cleanliness Median filtering is performed on the video frames in the space; Step 3: Calculate the cumulative difference map of cleanliness within seconds, and locate the water body discharge area; Step 4: Make a judgment on whether the frame water body is polluted; Step 5: Alert and store the video frame of sewage discharge. The invention can better distinguish sewage and clean water of various colors, and the method based on the cumulative change of cleanliness can "precisely" locate the flowing water body. Only storing the video information during the sewage discharge stage can provide a reliable reference for relevant departments to verify and formulate relevant treatment methods.

Description

technical field [0001] The invention belongs to the technical field of video detection, and in particular relates to a sewage discharge detection method based on HSV color space. Background technique [0002] Water is the basic resource for human survival. However, with the rapid development of social production and the continuous change of human life style, water pollution has become a living environment problem that cannot be ignored by human beings and needs to be solved urgently. At present, the problem of illegal discharge of domestic production and domestic sewage is relatively serious, especially in order to reduce production costs, some small factories discharge industrial sewage without treatment, which greatly damages the quality of surrounding water bodies and creates a series of secondary environments. question. [0003] The total amount of fresh water resources in my country ranks among the top in the world, but due to factors such as a large population and dif...
