Abstract

The invention provides a method, device and system for detecting a sewage draining exit based on combination of thermal imaging and ultrasound. The method comprises the steps of carrying out the imaging scanning of a to-be-detected water area through employing an ultrasonic probe, and collecting an underwater ultrasonic image, taking the underwater ultrasonic image as input, performing suspected sewage draining exit identification on the underwater ultrasonic image based on a pre-established deep convolutional neural network model, and outputting an identification result, when the identification result indicates that the suspected sewage draining exit exists, starting a thermal imager to carry out imaging scanning on a set area, and collecting a thermal imaging image, processing the thermal imaging image based on a gray scale identification algorithm, and judging whether the suspected sewage draining exit is a real sewage draining exit or not, and giving an alarm to the real sewage draining exit. The detection efficiency and accuracy of the sewage draining exit are improved; and environmental protection of important drainage basins is facilitated, and illegal sewage discharge is completely eradicated.

Description

technical field [0001] The invention relates to the technical field of image processing and recognition, in particular to a method, device and system for detecting sewage outlets based on the combination of thermal imaging and ultrasound. 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 nece...
