Abstract

The invention discloses a fish school detection method, system and device based on image recognition. The method comprises the steps of collecting a fish school image and performing target segmentation on the fish school image; performing target extraction and classification on the background difference image; sequentially carrying out contour extraction, skeleton extraction and head and tail extraction on the individual fish samples; constructing a crossed fish sample according to the head and tail positions of the individual fishes; constructing a training set and training a Yolo v4 network; and obtaining a to-be-detected image and inputting the to-be-detected image to the trained detection network. The system comprises a segmentation module, a classification module, an extraction module, a construction module, a training module and a detection module. The device comprises a memory and a processor used for executing the fish school detection method based on image recognition. By using the method and the device, the problems of local shielding, missing detection and error detection of the target caused by dense distribution of a large number of individuals with high similarity are solved. The method can be widely applied to the field of image processing.

Description

Technical field [0001] The invention relates to the field of image processing, in particular to a fish school detection method, system and device based on image recognition. technical background [0002] In recent years, the improvement of computer hardware and the development of computer vision technology have provided important technical support for the detection and tracking of group animals. Zebrafish, as a classic model organism, is widely used to study group behavior because of its simple structure and easy feeding. There are some problems in traditional fish detection methods, such as low efficiency, error-prone, false detection, or limited methods, requiring manual setting of multiple parameters, unable to segment the target effectively, and serious occlusion. It has a great influence on the accuracy and integrity of detection and tracking. Inventive content [0003] In order to solve the above technical problems, the present invention aims to provide a fish detection me...
