Abstract: A model of a mobile setup for shape reconstruction is presented. In this technique, the contouring is performed by laser scanning and image processing. The devices of this setup can be moved to examine occluded areas and small details. The algorithm of triangulation method computes the object dimensions from the deformation of a laser line and the camera position. This model improves the performance and the accuracy of the reconstruction system, because all steps of the contouring are performed by computer algorithms. In this manner, the errors of the physical measurements are not passed to the reconstruction system. This procedure represents a contribution to the methods of contouring based on laser scanning. To describe the accuracy, a root mean square of error is calculated with respect to a contact method. This technique has been tested with real objects. Also the new principle of the shaping the structured illumination suitable is considered for realization of pinpoint accuracy of the noncontact optical measuring systems for determination of the profile to surfaces greater object. Proposed method has no an analogue in Russia and overseas.
