Abstract

In this presentation, we will provide an introduction on how to create a high speed 3D scanner using a TI based DMD and machine vision cameras in order to create a robust 3D imaging system for different applications. Based on over a decade of experience of building industrial scanners for end user applications, we will focus on common pitfalls and provide a framework on how to evaluate the various types of structured light illumination patterns for measurement applications. The speed and flexibility of pattern projection capability offered by digital light processing technology, enables a huge amount of flexibility and options for tailoring different illumination patterns approaches to real world scenarios. In conjunction with the recent advances in imaging sensor technologies and embedded processing, this enables the rapid development of customized solutions. We discuss the trade-offs of various hardware choices. Several example applications are also discussed.
