Online color recognition-based industrial product rapid classification method and device

Abstract

The invention provides an online color recognition-based industrial product rapid classification method and a device. The device comprises a high-speed camera, an infrared photoelectric sensor, an air cylinder controller, an air cylinder set, an article collecting frame corresponding to each air cylinder and a control system. The control system controls the high-speed camera to collect the image of an article in real time. The image region of the article is extracted according to the background subtraction method, and the main tone of the article is determined by means of the clustering method. The color difference between the image of the article collected in real time and images in an established image library respectively, and then the color classification of the current article is figured out according to the principle that the color difference is the minimum. After that, whether the article is qualified or not is judged. The control system pushes the article into the corresponding article collecting frame by the air cylinder according to the judging result. The method and the device are high in automation degree and easy to operate. Products of the same kind and different colors can be quickly and accurately classified. Therefore, the method and the device can be well applied to various industrial fields.

Description

technical field [0001] The invention relates to a method and device for rapid classification of industrial products based on online color recognition, especially the automatic recognition and classification of the production line of the same type of products with different main colors. Background technique [0002] The production of items of the same type with different colors is an aspect of industrial production. Generally speaking, the color information of the product should be indicated on the packaging box. During the packaging process, items of different colors must be packed in corresponding packaging boxes. [0003] During the production process, some items are of a single color while others are based on one color and other colors are used as the color matching. Items of various colors are transported to the packaging workshop through the conveyor belt at the same time. Generally, the products are first classified manually and then packaged. Manual product classific...

Problems solved by technology

However, the automatic color recognition devices on the market can generally only distinguish a few types of colors, and the efficiency is not high enough. Now it is obviously unable to meet the needs of modern and efficient production.
