Problems solved by technology
These traditional methods often have high requirements for the implementation conditions. For example, the personnel using the test equipment have good eyesight, and can only be observed offline. The error is large and cannot be measured in real time. The hysteresis is large, which seriously affects the The Timeliness of Optimal Control of Water Body
Especially for some special application fields, such as aquaculture, if online and accurate monitoring of water quality transparency cannot be achieved, a large amount of additional labor costs and economic costs will be generated, which will have a significant impact on the economic benefits of the application

Embodiment 1
[0051] When testing the transparency of water quality, it is generally believed that the transparency is the penetration degree of sunlight in the water. The traditional Sai's compass detection method believes that the distance when the plane of the disc is just invisible to the naked eye is the transparency of the water body. However, the limitation of the traditional compass method is that the tester must have normal eyesight. Using human naked eye vision to record and measure the water quality transparency indicators of a certain area offline has brought a relatively large impact on the accuracy of the test results. There is a large subjective impact, and there is a large lag in the water quality intervention work based on the test results. At the same time, while the observation accuracy is difficult to guarantee, it also results in high manpower and material costs and low efficiency. Therefore, based on this problem, Embodiment 1 of the present invention provides a water ...

Abstract
The invention discloses a water quality transparency measuring system based on computer vision, and relates to the field of water quality monitoring. The water quality transparency measuring system can realize automatic detection and real-time measurement and transmission of water quality transparency of a water body. Compared with a traditional method for obtaining water quality transparency detection data by performing deep observation on a Saturi compass by naked eyes, the water quality transparency measuring system has the advantages that a computer vision device is used for replacing thenaked eyes to perform repeated and efficient water quality transparency measuring activities; in addition, the water quality transparency monitoring data can be analyzed and processed in a remote datacenter; the on-time on-demand on-line automatic measurement is realized; and the reliability and the efficiency of the water quality transparency measuring result are improved. The water quality transparency measuring method based on the computer vision provided by the invention can be integrated into on-line continuous monitoring equipment of the water quality; the errors caused by manual monitoring are reduced; very important guidance significance is realized on work such as lake eutrophication and water quality regulation of the culture industry.
Description
technical field [0001] The invention belongs to the field of water quality monitoring, in particular to a system and method for measuring water quality transparency based on computer vision. Background technique [0002] Water quality transparency indicates the clarity of the water body, and is one of the indicators specified by the Ministry of Water Resources’ national industry standards to be measured. It is often used as an important monitoring parameter in the fields of aquaculture, lake eutrophication monitoring, and marine ecology. Normally, the transparency of water quality is reflected by the amount of plankton and suspended matter in the water, and unsuitable water quality transparency will affect the living environment of plankton. The higher the transparency, the thinner the water body, the less phytoplankton in the water, and the weaker the photosynthesis. Most of the dissolved oxygen in the water body comes from the photosynthesis of phytoplankton. Weak photosy...
