Robotic Scanning Using a White Light Scanner on an Industrial Robot, Combined with an Optical Tracking System, to Digitize Automotive Doors and Hoods at AUDI

Abstract

A white light scanner on an industrial robot, tracked optically, digitizing car doors and hoods at AUDI. The attraction is obvious – the robot gives reach and repeatability across a large volume, the scanner gives dense data – and so is the problem: a robot is not a CMM, and the tracking system is what has to make up the difference. Erik Klaas describes the system setup of robot, tracking system and scanner, then reports accuracy testing to VDI: probing error, sphere spacing error and repeatability, with experimental results from the AUDI installation and what they say about where this approach belongs.
