Description

Technical Field

[0001] The utility model relates to the technical field of water body transparency measurement, in particular to a device for measuring water body transparency through full-automatic image recognition. Background Art

[0002] Water is transparent and colorless. When the water contains sediment, microorganisms, suspended solids, organic matter and other substances, turbidity will occur and the transparency of the water will decrease. The decrease in water transparency not only affects the sensory properties, but also affects the life of aquatic organisms. Therefore, water transparency is also an indicator of water quality.

[0003] When measuring water transparency, the water transparency disc method is usually used. The transparency disc is also called the Secchi disc. It is a disc made of thick raw bronze with a diameter of 1.5 mm. One side of the disc is divided into four parts from the center. It is painted with black and white lacquer alternately. A small hole is made in the center, a rope is passed through, and a heavy weight is added below. On a sunny day when the water surface is stable, the disc is lowered into the water with a rope until it is almost invisible when observed from above. The length of the part of the rope immersed in the water is measured several times. The average value is the transparency.

[0004] However, there are currently the following problems when using transparency disks to measure water transparency: due to the observation method used, each person's vision is different, and this method varies from person to person, which will affect the results of the experiment, and the device requires the human eye to read the data, which may result in certain errors and affect the test results.
