This paper introduces an automated 3D optical measurement system. In industrial inspection, coordinate measurement machines (CMMs) provide accurate measurement but are very time consuming because only one point can be acquired each time. An area sensor based robotic 3D measurement system can acquire an automotive part's surface patch-by-patch, which reduces the inspection time significantly. This paper describes a pixel-to-pixel sensor calibration scheme and a bounding box based sensor planning method which are developed for the automatic optical measurement system of large and complex surfaces. Experiment results are presented and discussed
