Abstract
In order to increase the measurement speed of pattern projection-based 3D sensors, we have developed a GOBO slide-based pattern projector (GOes Before Optics) which allows for pattern projection at several 10,000 fps. After first experimental configurations have been mainly set up based on empirical study, in this contribution, we investigate the capabilities of a GOBO projection-based 3D sensor on a theoretical level. We discuss and optimize the parameters which influence the completeness and accuracy of the 3D result, and we experimentally verify the theoretical results by means of a GOBO projection-based 3D sensor operating in the near infrared.
