Welding sensor uses structured light and 2D photocell

Abstract

Vision sensor for arc weld seam tracking uses a projected line of light scan from a high power infrared LED, which is detected by a two‐dimensional position‐sensitive photocell. It is compact enough to be mounted on a robot hand and works well on surfaces of poor reflectivity.
