Abstract

The embodiment of the invention provides a fish weight measuring and calculating method and a device, and the method comprises the steps: obtaining a photographing image corresponding to a to-be-measured and calculated fish, obtaining the position information of specific points of the to-be-measured and calculated fish according to the photographing image, and obtaining the actual distance betweenthe specific points according to the position information of the specific points and the pixel value of the photographing image; obtaining an image feature value of the eye of the fish to be measuredand calculated according to the shot image, and calculating an actual feature value of the eye of the fish to be measured and calculated according to the image feature value and the pixel value; selecting an actual distance between the specific points and an associated feature related to the weight of the fish in the actual feature values of the eyes of the fish to be measured and calculated through a preset association analysis method; and substituting the associated features into a preset neural network model, and performing calculation to obtain a weight prediction value of the to-be-measured fish output by the neural network model. By adopting the method, the weight of the fish can be accurately measured and calculated.

Description

technical field [0001] The invention relates to the technical fields of image analysis and processing and biological measurement, in particular to a fish weight measurement method and device. Background technique [0002] In the process of fish farming production, it is necessary to frequently obtain the weight characteristics of various fish, because the weight characteristics of fish provide key data for fishery production to control feeding, stocking density, quality grading, monitoring growth rate, and harvesting operations. In addition, it is also a key indicator of genetic selection. [0003] With the development of computer technology and machine vision technology, the weight of fish can not only be measured manually, but also the image of fish body can be analyzed by using machine vision technology, and then the weight of fish body can be accurately estimated. This method It can effectively reduce the intrusion and labor cost loss caused by manual weighing. [0004...
