Workpiece grabbing method and device based on vision system

Abstract

The invention provides a workpiece grasping method and device based on a vision system, and relates to the technical field of workpiece grasping. The method receives the actual image information of the workpiece collected by the vision system, and combines the actual image information with the preset image of the workpiece. The information is fitted and compared, the correction data of the actual image information of the workpiece and the preset image information are obtained, and the actual movement path of the actuator to grab the workpiece is analyzed according to the correction; the actuator is controlled to move to the grasping position along the actual movement path, And according to the preset grabbing action information of the actuator to grab the workpiece, control the action of the actuator to grab the workpiece; the background pre-processing technology is adopted, the amount of data analysis is small, and the time occupied by the system response and calculation is greatly shortened. It is beneficial to shorten the takt of automatic production, thereby improving the production efficiency and output of the production line.

Description

technical field [0001] The invention relates to the technical field of workpiece grasping, in particular to a vision system-based workpiece grasping method and device. Background technique [0002] With the rapid development of industrial intelligent manufacturing, automation and intelligent workpiece loading and unloading have developed rapidly. One of the common equipment is to combine vision and magnetic suction tools to realize the intelligent arrangement of magnetic suction point matrix relationship to cooperate with the manipulator. Complete the grabbing work of the workpiece. This kind of equipment for intelligent vision-guided magnetic suction tools takes visual pictures. After the pictures are taken, the processor analyzes the image information in real time, and calculates the position of the workpiece and the information of the equipped magnetic suction points. Among them, in the process of analyzing the image information in real time to obtain the information of ...
