Building block automatic sorting method and system based on binocular vision

Abstract

The invention discloses a building block automatic sorting method and system based on binocular vision, wherein the method comprises the steps of calibrating a camera; collecting the building blocks on a production line conveying belt through the calibrated camera, and generating the building block graphs; preprocessing the building block graphs to obtain the preprocessed building block graphs; carrying out image conversion on the preprocessed building block graphs to determine the colors of the building blocks; processing the images after the colors of the building blocks are determined, andobtaining the spatial position information of the building blocks; processing a picture collected by the camera, and obtaining the building block information serving as a sorting target; and sending the spatial position information and the building block information serving as the sorting target to a robot for the building block sorting. In the embodiment of the invention, a binocular vision method is used for identifying the spatial positions of the building blocks and automatically grabbing the building blocks, so that the identification and automatic grabbing of the building blocks in the industrial building block production are realized, and the problems of low efficiency and low accuracy in the building block sorting are solved.

Description

technical field [0001] The invention relates to the technical fields of industrial automatic identification and machine vision, in particular to an automatic sorting method and system for building blocks based on binocular vision. Background technique [0002] In the development process of industrial automatic identification technology, workpiece sorting is a tedious task. The initial sorting method is manual sorting. The speed and accuracy of sorting depend on the proficiency, fatigue and work attitude of workers. At the same time, sorting in some industries is dangerous or has strict requirements on the hygiene of the sorting environment. Therefore, it is of great significance to realize the sorting automation of workpieces. There are many types, shapes, and colors of building blocks, and numerous accessories also bring great trouble to the sorting of building blocks. [0003] The key to realizing the automation of workpiece sorting is whether it can accurately identify ...
