Marine organism target detection method and system, storage medium and equipment

The invention relates to a marine organism target detection method and system, a storage medium and equipment, and the method comprises the following steps: obtaining an original underwater image, and carrying out the enhancement processing of the original underwater image, and obtaining an enhanced underwater image; processing the enhanced underwater image based on the trained target detection network to obtain the position and category result of the marine organism in the image; wherein the target detection network carries out structured pruning on a C3 module of a YOLOV5 network feature fusion part, the number of channels before and after structure pruning is not changed, an attention mechanism is added to the position of the original C3 module, and the attention mechanism comprises a channel attention module and a space attention module. The YOLOV5 network is compressed by using a structured pruning method, so that the network complexity is reduced, the processing speed is improved, and the computing powe
