Squid quality grade identifying and sorting method

Abstract

The invention provides a squid identifying and sorting method which comprises the following steps of firstly, extracting a squid area from an image containing squids, then judging the orientation andintegrity of the squids through the area characteristics, extracting the necks of the complete squids through a morphological algorithm, calculating the body length, and dividing the squids into a plurality of grades according to the body length; for the incomplete squids, marking the squids directly as the lowest level; and according to the grading condition, controlling the external selection equipment to distribute the squids, thereby finishing classification. According to the method, the squids can be automatically identified and graded, the grabbing and distribution are controlled, the manual operation is not needed during the whole process, the intelligent degree is high, the manpower is greatly saved, the identification accuracy is high, and the classification result is reliable. The method can accurately and effectively sort the different types of squids and the aquatic products, such as cuttlefishes, octopuses, etc., which have the similar shapes with the squids.

Description

technical field [0001] The invention belongs to the field of object recognition and sorting, in particular to a squid quality grade recognition and sorting method. Background technique [0002] With the improvement of people's living standards, the types of diets have also been greatly enriched, and traditional high-priced ingredients such as seafood are gradually served on the tables of ordinary families, which also promotes the sales strategy of grading sales of the same kind of ingredients according to their quality. . Taking squid as an example, squid can be divided into several grades according to their integrity, weight, length, and whether there are quality defects. Different prices can also be set when selling. Squid with high integrity, large weight, long length, and few defects A high price can be specified, while squid with poor integrity and small size can be sold at a low price, which not only ensures the profit of the merchant, but also enables more low- and m...

AI Technical Summary

Problems solved by technology

At present, the classification of squid and other seafood mostly relies on manual sorting, and the existing automatic sorting equipment is also mainly classified according to weight, which cannot distinguish the integrity of squid, nor can it automatically calculate the length. Reflecting the appearance of squid still requires a lot of manpower and has limited effect
