KeywordsĪckermann, J., Michael, G.: A survey of photometric stereo techniques. We implemented our illumination planning with a programmable light source in an online manner, and achieve shadow-robust surface normal estimation from a small number of images. More specifically, our proposed method iteratively adds the optimal light source for surface normal estimation by taking the visibility and linear independence of light source directions into consideration on the basis of the previously captured images of the object. In this paper, we propose an illumination planning for shadow-robust Lambertian photometric stereo it optimizes the light source directions adaptively for an object of interest, because cast shadows depend on the entire shape of the object. In general, photometric stereo suffers from shadows, because almost no information on surface normals is available from shadowed pixels. Photometric stereo is a technique for estimating normals of an object surface from its images taken under different light source directions. ![]()
