Description

Technical Field

[0001] The utility model relates to the technical field of image acquisition, in particular to a device for acquiring images of fish in turbid water bodies. Background Art

[0002] In the fields of ecological environment monitoring and fish protection, the collection and analysis of fish image data are of great significance. Existing fishway detection equipment and underwater camera systems have been widely used in fish behavior research, species monitoring and ecological protection. These systems usually use optical camera technology to record the behavior and movement trajectories of fish in different environments. However, different water turbidity has a significant impact on image quality. Generally, the higher the turbidity, the lower the image clarity, which brings challenges to fish identification and data analysis. Under natural conditions, current fishway detection equipment has difficulty in obtaining clear fish images in water bodies with high turbidity, resulting in low data quality. In addition, under natural conditions, it is difficult to collect image data of rare fish and the data volume is insufficient, which affects the effective application of artificial intelligence recognition technology in the fields of ecological environment monitoring and fish protection.
