Problems solved by technology

If the environment around the workpiece changes, it is likely to cause the failure of the manipulator task. This shortcoming that the manipulator cannot recognize changes in the external environment greatly limits the application of the manipulator in industrial production.

Abstract

The invention discloses an elevator door plank feeding positioning method guided through vision. Accurate positioning on an elevator door plank is achieved through double cameras. The camera 1 is used for collecting left receding hole images of the elevator door plank. The camera 2 is used for collecting right receding hole images of the elevator door plank. The elevator door plank is positioned through comparison of a material conveying door plank and the standard position information of the door plank. A vision positioning unit analyzes the collected images, the actual displacement variation of the material conveying door plank is determined by comparing the coordinates of a datum point A with the coordinates of a datum point A0, and the actual angle variation of the material conveying door plank is determined by calculating the included angle alpha between the straight line A0B0 and the straight line AB. According to the method, a mechanical arm guided through vision can be helped to rapidly, accurately and stably grab the elevator door plank for feeding.

Description

technical field [0001] The invention relates to a material loading and positioning method for products, in particular to a visually guided elevator door plate material positioning method, which belongs to the field of product visual positioning. Background technique [0002] The identification and positioning of the workpiece is an important part of the effective application of the manipulator on the production line. At present, the manipulator has been widely used in the industrial production line, but many of them are pre-set under the teaching programming of the teaching staff or offline programming. Fixed actions and functions. If the environment around the workpiece changes, it is likely to cause the failure of the manipulator task. This shortcoming that the manipulator cannot recognize changes in the external environment greatly limits the application of the manipulator in industrial production. [0003] As the name implies, machine vision is to enable the robotic arm...
