编码结构光被认为是恢复物体表面最可靠的技术之一。该技术基于投射光图案并从一个或多个视点观察照明场景。由于对图案进行了编码，因此可以很容易地找到图像点和投影图案点之间的对应关系，解码后的点可以进行三角测量，从而获得三维信息。我们提出了现有技术的概述，以及一个新的和明确的分类模式的结构光传感器。我们已经实现了一套代表性的技术在这一领域，并提出了一些比较结果。并对不同模式的优势和局限性进行了讨论。(C)2003模式识别学会。由爱思唯尔有限公司出版。保留所有权利。
Coded structured light is considered one of the most reliable techniques for recovering the surface of objects. This technique is based on projecting a light pattern and viewing the illuminated scene from one or more points of view. Since the pattern is coded, correspondences between image points and points of the projected pattern can be easily found. The decoded points can be triangulated and 3D information is obtained. We present an overview of the existing techniques, as well as a new and definitive classification of patterns for structured light sensors. We have implemented a set of representative techniques in this field and present some comparative results. The advantages and constraints of the different patterns are also discussed.
