摘要
Fringe projection profilometry is widely used in optical metrology, and fringe analysis is important to improve measurement accuracy. However, the fringe images captured by cameras are influenced by many factors, an analytical study of which, to characterize the imaging process, is difficult to perform. We propose a method to accurately simulate the real imaging system in the virtual environment using ray tracing algorithm. The light transport coefficients of the cameras are measured to simulate defocus instead of using Gaussian function. Experimental results show that the proposed method can simulate a physical system in the virtual environment more accurately than the Gaussian function at large defocus condition.
