Accuracy Assessment of Structured-Light Based Industrial Optical Scanner

This paper presents accuracy assessment of structured light based industrial optical scanner. Comet LED 5M scanner, as an active stereo system, is calibrated using different approaches, and the impact of the calibration results on the system accuracy is verified in experiments. Besides predefined system accuracy verification, an additional method is proposed, and the obtained results were compared. Experimental results show that the system fulfills highly rigorous requirements, even in not strictly controlled environment, thus making it very suitable for use in, not only industrial but also in high precision and high sensitive applications.
