Structured light systems are popular in part because they can be constructed from off-the-shelf low cost components.In this paper we quantitatively show how common design parameters affect precision and accuracy in such systems, supplying a much needed guide for practitioners.Our quantitative measure is the established VDI/VDE 2634 (Part 2) guideline using precision made calibration artifacts.Experiments are JORDAN 4 performed on our own structured light setup, consisting of two cameras and a projector.
We place our focus on the influence of calibration design parameters, the calibration procedure and encoding strategy and present our findings.Finally, we compare our setup to a state of the art metrology grade commercial scanner.Our results show that comparable, and in Signage some cases better, results can be obtained using the parameter settings determined in this study.
