System and method for fish behavior quantitative observation

Abstract

The invention discloses a system and method for fish behavior quantitative observation. The system comprises a calibration unit, a binocular vision observation unit, a rapid storage unit and a behavior analysis unit, wherein the binocular vision observation unit is fixedly arranged on an adjusting arm of camera adjusting apparatus through a damping pan-tilt, an observation angle of cameras can beconveniently adjusted through the damping pan-tilt and is sent to the rapid storage unit, the rapid storage unit comprises an image compression board card and a network storage server, the binocular cameras collect images and are connected with the image compression board card, the images are compressed by the image compression board card and stored in the storage server, the behavior analysis unit realizes the preliminary positioning of fishes in the images by using a motion difference method, an optimal observation angle is determined in combination with similarity evaluation, then a shape-based centroid estimation algorithm is introduced to determine the center of gravity of a moving object, positioning of moving fishes is realized, and the movement speed, acceleration, water layer distribution and the like of the fishes can realize movement behavior quantification through a centroid extraction method.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a system and method for quantitative observation of fish behavior. Background technique [0002] Currently, underwater observation is usually based on the image acquisition of a single camera or video camera. The existing image acquisition technology can only obtain image information from one angle when observing underwater organisms, and there are a large number of visual blind spots. However, there are many types of underwater organisms and various forms. The image information obtained through traditional image acquisition technology is not enough to obtain Observing the complete morphological feature information of organisms leads to the lack of objectivity of the observation results, and this problem also needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to provide a system and method for quantitative observation of fish beha...
