Single stripe projection based range scanning of shiny objects under ambient light

Range scanners are used in various applications in industry. Therefore, various range scanners, based on different working principles are developed. Among these, scanners using stripe based triangulation are the most promising ones. Unfortunately, these scanners have problems in obtaining the range data of shiny objects (having highlights) under ambient light. In this study, we develop a stripe projection based range scanner to solve this problem. Our main contribution is on detecting the stripe using a color invariant in a robust manner. We developed a projector based scanner using this color invariant. Our scanner has also the advantage of flexibly changing stripe color for different colored objects. We test the performance of our novel stripe detection method under various controlled experiments. We also test the overall performance of our scanner in extracting the range data of several objects having highlights. Extensive testings indicate the success of our range scanner, especially for scanning objects having highlights under ambient light.
