Fish phenotypic characteristic measurement method and system, electronic equipment and storage medium

The invention relates to a fish phenotypic characteristic measurement method and system, electronic equipment and a storage medium, and belongs to the field of fish phenotypic characteristic measurement. The method comprises the steps of obtaining an underwater image of an aquaculture water area; preprocessing the underwater image by using a deep learning model to obtain an underwater image containing a plurality of prediction frames; carrying out noise reduction processing on the underwater image containing the plurality of prediction frames to obtain a denoised underwater image; determining a target prediction frame according to the denoised underwater image; according to the target prediction frame, determining the position of a target and fish phenotypic characteristics; the fish phenotypic characteristics comprise the body length, the body width and the body weight of the target fish. According to the invention, the efficiency and accuracy of fish phenotypic characteristic measurement are improved. 本发明涉及
