Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water body image acquisition device for image turbidity recognition. Background Art

[0002] Turbidity refers to the degree of pollution in water, that is, the degree of obstruction caused by suspended matter in water to the transmission of light. Water may contain suspended matter and colloid substances such as mud, dust, fine organic matter, zooplankton and other microorganisms, which will cause the water to have different degrees of turbidity. The turbidity of water reflects the degree of obstruction caused by suspended matter, colloid substances and microbial impurities of different sizes, specific gravities and shapes in the water to the transmission of light.

[0003] Turbidity measurement is widely used in various industries and sectors such as water supply, brewing, pharmaceuticals, environmental protection, and health and epidemic prevention. Especially in water quality monitoring, turbidity is an important parameter used to characterize the quality of water.

[0004] At present, there are two main methods for detecting water turbidity: 1. On-site collection combined with laboratory analysis. Specifically, the water sample collected on-site is compared with the turbidity standard solution prepared with kaolin to detect the turbidity of the water sample; 2. Turbidity sensor based on the scattered light method. Specifically, the turbidity value of the water quality is determined by passing the incident light through the water sample and detecting the amount of light scattered by the particles in the water at 90° to the incident light.

[0005] The above two methods have their own advantages and disadvantages. The first method has a higher turbidity detection accuracy, but is not suitable for online detection in the field; although the second method is suitable for field work and can realize online detection of water turbidity, its detection accuracy is low.

[0006] With the development of image recognition and neural networks, many scholars have begun to study the use of water images to identify the turbidity of water. This method can not only save the time required to measure turbidity and improve detection efficiency, but also reduce the errors caused by manual operation. In the early stage, the image recognition neural network needs to be learned, so a large number of water quality image samples need to be provided. The existing image sample collection is generally done by staff directly manually shooting water samples without corresponding shooting devices, resulting in different shooting angles and light intensities each time the sample is shot, which leads to other problems such as increased difficulty in learning the image recognition neural network and increased learning time.

[0007] Therefore, there is an urgent need for a device that can collect and photograph water quality samples under scientific and standardized conditions. Utility Model Content
