In order to construct a 3D model of object lacking of texture, the main difficulty for registration is the lacking of feature points and the obtaining of the points' coordinates. The method handles registration problem based on the Iterative Closed Point (ICP) algorithm, which requires only the procedure to find the closed point on a geometric entity to a given point. The ICP algorithm is a popular method for the registration, when there is lack of feature points. In order to compute the points' coordinates, the projector can provide the clear and stable texture on the surface of the object lacking of texture easily. The camera is used to take photos as the image data for the next processing. Using curve detection and space intersection, spatial points on the surface of the sheet metal parts are obtained. Sub-Models overlapping each other are registered by ICP, so the 3D reconstruction is finished. The feasibility of ICP is verified by the results of the experimentation.
