A study on the welding seam tracking by using Laser Vision Sensor

Abstract

This paper suggests one of the pre-measurement methods to trace a welding path. The welding path is measured by the LVS (Laser Vision Sensor). A line laser is projected on the weldment and a vision sensor captures images. Center points of the welding path are detected through image processing. Measured image coordinates are transformed to robot coordinates… (More)
