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

Embodiment

[0032] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for identifying and sorting squid quality grades. The method is implemented by software and needs to cooperate with external grabbing and sorting equipment to carry out squid sorting operations, specifically including the following steps:

[0033] S1: Shoot the squid through peripheral cameras and other equipment, acquire the image to be recognized, and extract the squid area from it. The following methods can be used to remove the background and obtain the squid area:

[0034] (1) Extraction by saturation threshold:

[0035] Since the appearance color of the squid to be detected is mainly white, brown, brown and other low-saturation colors, and the overall saturation is below 120, in order to identify the squid area, the background can be set to a higher color saturation (up to 230 or more). ) color (preferably blue, green, yellow), so that it forms a sharp contrast with the low-satura...

Abstract

The invention provides a method for identifying and sorting squid. First, the squid region is extracted from an image containing squid, and then the orientation and integrity of the squid are judged through the regional features. For a complete squid, the neck, neck, And calculate the body length, divide it into several grades according to the body length; for incomplete squid, then directly mark it as the lowest grade; according to the classification situation, control the external sorting equipment to distribute the squid, so as to complete the classification. This method can automatically identify, classify and control the grabbing and distribution of squid. The whole process does not require manual operation. It is highly intelligent, greatly saves manpower, and has high recognition accuracy and reliable classification results. Aquatic products such as cuttlefish and octopus, which are similar in shape to squid, can be sorted accurately and effectively by using this method.

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...
