Study on Weld Seam Tracking System Based on Laser Vision Sensing

Article Preview

Abstract:

Seam tracking is a basic condition to ensure a fine welding shape. In order to meet this requirement, the researchers have put forward a variety of sensors and some of them have been applied to practice successfully, such as contact sensor, arc sensor and vision sensor. Laser vision sensor has been proven to be one of the most successfully technology for its many advantages. In this paper, based on laser visual sensing technology, a seam tracking system is established with an embedded microcontroller LPC1768. With this system, a real-time tracking algorithm is proposed and the seam tracing process is realized under a smaller error. Finally, the tracking errors resources and their influence have been simulated and analyzed.
