Abstract: Because the three-dimensional surface texture can display the texture information of the object better than the two-dimentional lamination and can vary with scene illumination and the view angles，it is widely used in virtual reality and computer games.Photometric Stereo，as one of the effective technologies for capture of three-dimensional surface texture information，has attracted wide attention.Uniform illumination is the essential condition for the capture and reconstruction of three-dimensional surface texture using Photometric Stereo.In practice，non-uniform illumination leads to distorted surface heightmaps during the capture and reconstruction processes.This paper aims to eliminate this kind of distortion and aberration and proposes a simple method to solve the issue.The experimental result shows the effectiveness of the proposed method.
