Structured light tracks seams

Abstract

Describes a rugged, high speed structured laser light triangulation‐based vision‐type sensor, with real‐time image processor, along with some actual applications. High speed is essential for a low dynamic error at the laser welding speed (10m/minute). Square butt joint, frequently used in welding, requires high sensor resolution and a complementary detection technique based on the reflected light intensity. Shows some welding techniques, based on the joint geometry measurements; illustrates capabilities of the vision‐based sensor.
