Calculation system and method of factory-like circulating water cultured fish space

Abstract

The invention relates to a calculation system of a factory-like circulating water cultured fish space and a calculation method of the factory-like circulating water cultured fish space. The calculation system includes a near infrared camera, a near infrared light source and a processing device, wherein the near infrared camera and the near infrared light source are arranged at the upper part of a fish pond; optical axis rays of the near infrared light source are arranged at the upper part are perpendicular to the water face of the fish pond, and connected with the processing device; the infrared light source is used for supplementing light for the near infrared camera under the control of the processing device; the infrared camera is used for collecting a near infrared image of fishes under the control of the processing device; the processing device is further used for receiving the near infrared image to process and obtain the fish swimming speed. The calculation method is used for calculating the fish swimming speed. The calculation system can be applied to the factory-like circulating water cultured fish space with dark light; a light supplementing lamp is not required to add, the growth environment of fishes is not changed, thus the growth is not influenced. The calculation system can monitor the swimming speed of fishes in real time and provide reliable basis for monitoring fish behaviors.

Description

technical field [0001] The invention relates to fishery information technology, in particular to a system and method for calculating the spatial position of fish in industrial circulating water culture. Background technique [0002] As the scale of factory aquaculture increases, it is necessary to monitor the behavior of the aquaculture objects in real time. Among them, the swimming speed of fish is an important indicator to measure the behavior of fish groups, so timely and accurate acquisition of fish swimming speed can provide an important basis for subsequent behavioral analysis (such as fish disease early warning, feeding control, etc.) . [0003] At present, the fish position calculation method estimates the position of the fish by using a monocular, binocular or multi-eye stereoscopic machine vision method, which has the advantage of low cost. In practical applications, a single camera can only estimate the two-dimensional position information of the fish, and binoc...
