The invention relates to the technical field of water body concentration field measuring methods, and discloses an optics-based water body concentration field measuring method. The optics-based water body concentration field measuring method comprises the following steps: (1) calibrating a normal concentration refraction table; (2) putting a water body, which is to be determined, in a transparent water box, wherein an irradiating side wall of the water box is provided with a grating plate which is in longitudinal extension arrangement, the grating plate is provided with multiple horizontal grating gaps which are arranged at intervals longitudinally and in parallel, and horizontal light shading plates are arranged between adjacent horizontal grating gaps; (3) irradiating the side wall by utilizing parallel light rays emitted by parallel light sources; and shooting the side walls of the water box by utilizing a video camera so as to form analysis images; (4) carrying out image processing and projection straight line fitting on the analysis images, and calculating the refractive index of the parallel light rays which pass through the horizontal grating gaps; and (5) by contrast with the normal concentration refraction table, obtaining layer-by-layer measurement of corresponding water body concentration, and then getting measurement of a whole water body concentration field.
Description
technical field [0001] The invention relates to the technical field of water body concentration field measurement methods, in particular to an optical-based water body concentration field measurement method. Background technique [0002] In the study of environmental pollution, people are most concerned about the distribution of pollutants in space. The concentration field of pollutants in water bodies is an important indicator to measure the degree of water pollution. Or, when using physical models to conduct scientific research on hydraulics and water ecology, etc. When it is time, it is very important to measure the concentration and distribution of substances in the water body. Therefore, the measurement method of the concentration field of the water body has become one of the research hotspots of environmental workers. [0003] In the prior art, there is still a lack of effective means for measuring the concentration field of water body, and the traditional single-point...
