Abstract

The invention discloses an underwater salmon weight estimation method and system based on machine vision, and the method comprises the steps: obtaining a salmon picture data set, training the salmon picture data set through a deep learning algorithm, and obtaining a salmon recognition model; shooting an underwater image through a camera; identifying and marking the salmon in the underwater image by using a salmon identification model; obtaining an estimated distance from the camera to the salmon; calculating the estimated length of the salmon through the estimated distance; and obtaining the estimated weight of the salmon according to the estimated length. On the basis, the weight of the salmons can be estimated underwater at low cost, the camera equipment can freely move underwater, multiple salmons can be detected at a time, and the working efficiency is greatly improved.

Description

technical field [0001] The embodiments of the present invention relate to, but are not limited to, the technical field of machine vision, and in particular, relate to a method and system for estimating the weight of underwater salmon based on machine vision. Background technique [0002] In response to the national strategy of strengthening the country by sea, it is necessary to improve the automation level of fish farming in my country. Due to the great potential of China's salmon farming market, it is of great practical significance to study how to improve the efficiency of aquaculture and reduce the difficulty of management. [0003] The current underwater aquaculture system has three major shortcomings. First, the equipment can only be placed in a fixed location, cannot be moved and is expensive. Second, the cost of underwater aquaculture systems is extremely high. Third, it is not efficient enough to detect only one salmon at a time. SUMMARY OF THE INVENTION [00...
