Abstract :
Coded structured light is an effective technique to acquiring shape in stereovision. Coding strategy is one of the core techniques because it effects the measure precision and efficiency directly. There are two major group of techniques in color structured light encoding. One is to define coloured multi-slit, which is suitable for locating intensity peaks in the image. The other is to define coloured stripe patterns, which is suitable to locate edges. In this paper, we combine the two methods to design new coloured stripe patterns, so that both intensity peaks and edges can be located. Then, edge detection method with sub-pixel accuracy is performed and the detected stripes centres and the edges between adjacent stripes are matched with the projected pattern, which is the foundation for further dense reconstructions. The experimental results show that our methods are very powerful in terms of accuracy and resolution.
