| Abstract | This work is as a tool within the framework of the 3D reconstruction using a structured light projection associated with a 3CCD camera. The principle is easy: it is necessary to lay out a 3CCD camera and a LCD projector like a traditional stereovision system, in front of the studied scene. The use of a structured light raises a lot of ambiguities compared to a stereovision system with two cameras. However, the use of the color to code projection reduces the use of the system to white or pale objects. To determine the color and the 3D reconstruction of the object at the same time, it is necessary to have perfectly cleaned color images. We thus will describe a method of pre-processing of the color images from the 3CCD camera used. The images thus treated can be used in the color model which we will follow to give information of color of structured light to raise ambiguities of matching, and the color of the scene at the considered points. |
