Title:
METHOD FOR ESTIMATING BODY LENGTH AND WEIGHT OF PRAWN ON THE BASIS OF DIAMETER OF EYEBALL THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/004026
Kind Code:
A1
Abstract:
A method for estimating the body length and the weight of a prawn on the basis of the diameter of an eyeball thereof, in which an image of an eyeball of a prawn is acquired, data of the diameter of the eyeball of the prawn is accurately obtained by means of software analysis, and data of the body length and the weight of the prawn can be accurately determined according to a fitting model of the diameter of an eyeball and a body length and a fitting model of the diameter of an eyeball and a weight. The coefficient of correlation between the diameter of an eyeball and the weight of a prawn, which is measured by means of the present method, is equivalent to the coefficient of correlation between a body length and a weight, and the eyeball of a prawn can autofluoresce in a weak light condition, facilitating image recognition by a computer, achieving automated monitoring.
