Aquaculture living body online growth monitoring device and method based on 3D image

Abstract

The invention discloses an aquaculture living body online growth monitoring device and method based on a 3D image, and relates to the technical field of aquaculture. The device comprises a floating assembly, an adjusting assembly is arranged at the bottom of the floating assembly, and a monitoring assembly is arranged at the bottom of the adjusting assembly; the floating assembly comprises a floating plate, a mounting rod and an air bag. The floating plate is provided with the air bag through the mounting rod. The adjusting assembly comprises a first waterproof shell, an electric push rod and a lifting plate. The first waterproof shell is provided with the lifting plate through the electric push rod. The monitoring assembly comprises a second waterproof shell, a motor and a 3D camera, and the second waterproof shell is provided with the 3D camera through the motor. The monitoring assembly is driven to move in the culture pond through a floating plate and an air bag in the floating assembly, so that monitored data better conform to the actual situation, the monitoring assembly is driven to vertically move through an electric push rod and a lifting plate in the adjusting assembly, a 3D camera is driven to rotate through a motor in the monitoring assembly, and the monitoring accuracy is improved. And monitoring in multiple directions is realized.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a 3D image-based online growth monitoring device and method for aquaculture living bodies. Background technique [0002] In aquaculture, in order to avoid large-scale death of the cultured living organisms, an online growth monitoring device is usually installed in the breeding pond or breeding box, and the online growth monitoring device is used to realize the growth of the living body in the breeding pond or breeding box. Real-time monitoring is carried out, so that the breeding personnel can timely process the living body in the breeding pond or breeding box according to the monitored data, and improve the survival rate of the living body. [0003] The prior invention publication number CN110476871A discloses a cultured fish growth monitoring system, including an underwater vision device, a control device, a cloud platform and a monitoring terminal; the underwa...

Problems solved by technology

[0004] 1. A cultured fish growth monitoring system in the above-mentioned document. It is mentioned in the above-mentioned document that the cable is arranged inside the hollow tube vertical rod; the fixing part of the fixing bracket is arranged on the hollow tube vertical rod, The clamping part of the fixed bracket is clamped on the box body of the breeding box, and the device is installed on the side wall of the breeding box through the hollow tube vertical rod and the fixing bracket, so that the underwater visual device in the above-mentioned document can only The growth of aquatic organisms around the side wall of the breeding box is monitored, and the monitored data has limitations, so it is not easy to use

[0005] 2. A cultured fish growth monitoring system in the above-mentioned document, in which it is mentioned that the underwater visual device is fixedly installed on the bottom or side wall of the breeding box, or floats on the water surface of the breeding box, The growth of aquatic organisms can be monitored through underwater vision devices, but underwater vision devices can only detect the growth of aquatic organisms at the bottom or on the water surface, so it is not easy to use

[0006] 3. A cultured fish growth monitoring system in the above-mentioned document. It is mentioned in the above-mentioned document that the underwater visual device is fixedly installed on the bottom or side wall of the breeding box, or floats on the water surface of the breeding box, The shooting direction of its underwater vision device is fixed, so it is not convenient to monitor the growth of aquatic living organisms in multiple directions, so it is not convenient to use
