Vision control system of autonomous mobile welding robot

Abstract

The invention belongs to welding field and specifically relates to a vision control system of an autonomous mobile welding robot. On the basis of a welding robot, core image capture, processing and welding automatic control function are achieved by adopting a control system based on ARMCortex-A8. Welded joint image information of a laser vision sensor can be obtained by the control system. Position and size information of a welded joint is measured in real time according to the image information. Crawling, transverse swinging, automatic control of conducting of welding and real-time rectifyingof a deviation of a mobile robot are controlled through the control system. Overall complexity and equipment volume of the system can be reduced remarkably by an embedded system. Adaptability of theautonomous mobile welding robot in industrial field welding is improved.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a vision control system for an autonomous mobile welding robot.
