Problems solved by technology

Conventional sewage monitoring is mainly carried out by on-site sampling, indoor analysis and testing, etc. However, due to the complexity of water pollution, it can only be carried out by a large number of sampling methods, which consumes a lot of manpower and the positioning is often not accurate enough

Embodiment 1

[0033] See figure 1 , figure 1 It is a schematic flow chart of the method for monitoring illegal discharge of sewage in this embodiment; the method mainly includes:

[0034] S101. Obtain multiple groups of images to be processed collected at the same time and at different monitoring points in the water area to be monitored, and each group of images to be processed includes a thermal imaging image collected at the same monitoring point.

[0035] See figure 2 As shown, the water area to be monitored includes, for example, water sources such as rivers, lakes, and reservoirs. By pre-arranging monitoring equipment in the water area to be monitored, such as arranging monitoring cameras at intervals along the river bank, that is, different monitoring points, the monitoring cameras here need to be infrared cameras. Among them, the monitoring points (or the distance between the monitoring points) and the collection time interval can be flexibly set according to the actual situation...

Embodiment 2

[0062] On the basis of the first embodiment above, a monitoring device for illegal discharge of sewage is provided, which is used to realize the steps of the method for monitoring illegal discharge of sewage in the first embodiment above, please refer to image 3 , the monitoring device mainly includes:

[0063] Several image acquisition modules 31 are used to collect multiple groups of images to be processed at different monitoring points at the same time, and each group of images to be processed includes a thermal imaging image collected at the same monitoring point; optionally, it includes a thermal imaging camera and a video camera, each group of images to be processed also includes a video image collected at the same monitoring point; wherein the thermal imaging camera is used to collect thermal imaging images, and the video camera is used to collect ordinary visible light images.

[0064] The image analysis module 32 is used to convert each thermal imaging image into a g...

Abstract

The invention provides an illegal sewage discharge monitoring method and device and a computer readable storage medium. The method comprises the steps of obtaining a plurality of groups of to-be-processed images collected in a to-be-monitored water area at the same moment and different monitoring points, wherein each group of to-be-processed images comprise a thermal imaging image collected at thesame monitoring point; converting each thermal imaging image into a grayscale image, and calculating an average grayscale value of each grayscale image; calculating an average grayscale difference between every two grayscale images; if the average grayscale difference exceeds a set error threshold range, determining that a discharge port exists in the to-be-monitored water area for sewage discharge; determining an image block area corresponding to the to-be-monitored water area in the same grayscale image; detecting a grayscale difference between the minimum grayscale value and the maximum grayscale value in the image block area; comparing the grayscale differences of the grayscale images, determining the grayscale image with the maximum grayscale difference as a target grayscale image ofthe position where the discharge port is located; and carrying out sewage discharge alarm on the water area to be monitored.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a method, device and computer-readable storage medium for monitoring illegal discharge of sewage. Background technique [0002] With the continuous development of social economy and the deepening of urbanization process, the amount of sewage generated by social production and residents' life is increasing year by year. Water environment governance and water security have become one of China's most important tasks at present. In order to further improve the sewage treatment business. It is imperative to effectively control costs, carry out traceability of sewage discharge outlets more scientifically and rationally, and effectively control pollution at the source. [0003] Water resources are of special importance to human beings. Water pollution has become a problem that must be solved in the development of the country. It is very necessary to find a method that...
