SVD Photometric Stereo


Estimated shape	Estimated shape

We developed a method to acquire the 3D shape of opaque objects. We estimated the light source directions using SVD (singular value decomposition), and estimated the surface normal using the photometric stereo. We iteratively computed the SVD so that it will be less sensitive to shadows and specular reflections.
