Abstract

The invention discloses a statistics-based biomass evaluation device and method for deep-sea culture net cages, including an unmanned boat and a binocular camera, the binocular camera is arranged in the center of the camera frame, and the camera frame passes through an anchor chain Mounted on the unmanned boat, the unmanned boat is equipped with a mooring chain retractable module, a wireless communication module and a controller, the wireless communication module receives remote commands to the controller, and the controller transmits to the binocular camera The video data is identified and stored, and the total mass of organisms in the cage is calculated through a statistical model based on the identification results. The invention adopts visual recognition, which is safer; the video frame structure, the means of identification are rich in data, which is convenient for biomass identification; the acquisition of biomass data is real-time and continuous, and the continuous growth of fish can be obtained, providing data for refined breeding management Support; observation and statistics are carried out at the same time, intuitive and efficient.

Description

technical field [0001] The invention relates to a biomass evaluation device and method, in particular to a statistics-based biomass evaluation device and method for deep sea culture cages. Background technique [0002] Improving the ability to develop marine resources, focusing on promoting the transformation of marine economy to quality and benefit; protecting the marine ecological environment, focusing on promoting the transformation of marine development methods to recycling is the development direction of the national marine strategy, and deep-sea aquaculture has become a trend. [0003] At present, the deep-sea aquaculture technology is not mature and perfect. One of them is that the biomass in the aquaculture cage cannot be fully grasped in real time, which hinders the mining of the maximum economic value data and experience summary of aquaculture products, and is not conducive to the integration with other industries. Development, such as the financial and insurance i...
