Abstract
Based on the theories of texture mapping in the Photorealistic Graphics and ray-tracing algorithm, this paper proposes a novel method to simulate the real three-dimensional shape measurement system by projecting a sinusoidal stripe texture on computer 3D models, which are generated by the ray-tracing algorithm. The sizes of the main error sources of the real measurement system can be determined by comparing the real measurement result and the simulation one when measuring a standard block, higher accuracy of the simulation system are achieved by adding these error sources, then the source of the errors in the measured object can be achieved in the same way.
