  • METHOD OF REBUILDING 3D SURFACE MODEL
    Publication number: 20100103169
    Abstract: A method of rebuilding a 3D surface model is provided herein. The method includes the following steps: obtaining a 3D position and the reflectance parameters corresponding to an object according to the structured light system; building a synthesized image according to the 3D position and the reflectance parameters; then, optimizing the reflectance parameters for the synthesized image until the cost functions are smaller than a predetermined value. The invention presents an optimization algorithm to simultaneously estimate both a 3D shape and the parameters of a surface reflectance model from real objects.
