Problems solved by technology

However, this method has the following problems: 1. Using an acoustic system to affect the living habits of fish and the growth of cultured organisms; 2. There are errors and interferences in the density and density distribution of biota through echo signals, which have a great impact on the evaluation results , the accuracy of the evaluation results is not enough

Abstract

The invention discloses a device and method for evaluating biomass of deep offshore sea culture cages based on statistics. The device comprises an unmanned boat and a binocular camera; the binocular camera is arranged in the center of a camera frame; the camera frame is mounted on an unmanned boat through an anchor chain; the unmanned boat is provided with an anchor chain handling module, a wireless communication module and a controller; the wireless communication module receives a remote command to the controller; the controller identifies and stores video data transmitted by the binocular camera; and the total mass of organisms in a cage is calculated through a statistical model according to the identification results. The device and method adopting visual recognition have better safety;the camera frame structure is adopted, identification means data are rich, and therefore, biomass identification is facilitated; biomass data acquisition has good timelines and continuity, continuousfish growth conditions are attained, and data support is provided for fine farming management; observation and statistics are carried out simultaneously, so that high efficiency is achieved with goodvisuals.

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...
