—According to the sensing principle of coded structured light, and the characteristics of broad complication and high parameters request, a new coded structured light mathematics model and measurement method is proposed, which can simply and quickly obtain depth information of targets. Model is simulated by computer. It can gain the offset and deformation of pattern images based on different model parameters. For the deformation of images, system parameters can be changed correspondingly. So, whole system can be fixed on using optimal system parameters. The experiment results reveal that the method of structured light model and simulation proposed are reasonable and effective, which have important theoretical value and practical signification.
