A Simulation Method of Three-dimensional Shape Measurement System Based on Texture Mapping and Ray-tracing Algorithm
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.
