Embodiment

[0049] In the underwater fishing method based on machine vision in this embodiment, the underwater fishing device includes a Kang Nai In-Sight7000 type industrial camera for collecting images, an underwater lighting lamp for lighting in a dark environment, and an underwater lighting device for inducing fish. Fish lure light device and underwater special fishing net and underwater robot for catching fish, wherein the fish lure light device includes three-color LED and frequency conversion sounder; in addition, considering the blue-green color of underwater light propagation Offset, the underwater lighting is selected as a thallium iodide lamp, most of its radiated light energy is concentrated in the blue and green range, and water absorbs little to it; compared with incandescent lamps, this light source is used in underwater cameras Under the same power condition, the efficiency is more than six times.

Abstract

The invention relates to an underwater fishing method based on machine vision, and the method comprises the steps: monitoring the growth condition of fishes in real time through the cooperation of anunderwater fishing device and the steps of fish recognition and classification, fish length measurement and weight prediction, and accurately mastering the optimal fishing period; wherein the fish identification classification comprises image acquisition and preprocessing, wavelet feature extraction and BP neural network fish image classification, and the fish length measurement and weight prediction comprises fish sample length and weight parameter acquisition, fish length information extraction, length error compensation and weight prediction. The underwater fishing method based on machine vision has the advantages that fishes of specific types and specific sizes can be captured, meanwhile, the weight of the fishes can be estimated, the growth condition of the fishes can be monitored inreal time, and the optimal fishing period can be accurately mastered.

Description

technical field [0001] The invention relates to an underwater fish catching technology, in particular to an underwater fishing method based on machine vision. Background technique [0002] The main targets of marine fishery production are dense populations of fish or economic animals that are migrating, breeding, feeding or overwintering, especially breeding populations, which have high density and stability, and most fish populations are of the same length. Groups or clusters of the same age group, such as salmon and trout, are particularly obvious. [0003] Therefore, during fishing operations, if cruel fishing is carried out on objects (such as young or sexually immature juveniles) that do not meet the fishing specifications, the gain will not be worth the loss, which will seriously affect the amount of resources in the coming year, and even lead to the decline of fishery resources. , Endless troubles. Therefore, to achieve sustainable and rational fishing, it is necess...
