Three Dimensional Surface Reconstruction Based on the Reference Object and PMS

摘要

Three-dimensional surface reconstruction based on photometric stereo requires accurate positioning of the light source or estimation of the lighting parameters, which increases the complexity of the operation in experiments. Moreover, the actual light environment is composed of many kinds of complex optical components, and the accurate lighting parameters cannot be measured. In this paper, a reference object (Lambertian zirconia ball) is used to estimate the lighting parameters of the actual light environment, and then the lighting matrix of the target object can be deduced based on the same light scene of the reference object and the target object. With the estimated lighting matrix, the surface normal of the target object can be quickly computed. The experiment results of the synthetic and real object have verified the effectiveness of the proposed method.
