3D Reconstruction with Image-to-World Transformation

In the previous chapter, the DLP projector is used as a virtual camera and the structured light system is treated as a stereoscopic vision system. In this chapter, we take the projector as a collection of light planes and study the possible algorithms for 3D Euclidean reconstruction with such a system. The plane-based formulation is explored to take advantage of the light planes in the pattern projection. The computational complexity of the algorithm is also analyzed and compared with the traditional triangulation method. The image-to-world transformation is employed for the 3D Euclidean reconstruction considering two different cases, i.e. two-known-plane case and one-known-plane case. Finally, some examples and experimental results are presented using the suggested system.
