Reconstruction of 3D models from specular motion using circular lights

This work generalizes a shape recovery method for specular surJaces. We have used linear lights that generate planes of ray to highlight a rotating object so that its specular su$aces m computed from continuous images. By setting lights properly, shape at each rotation plane can be measured and a 30 graphics model can be subsequently reconstructed. In this paper, we extend our lights to circular ones to produce cones of ray. Under such illuminations, all su&ce points with different normals will be highlighted in a rotation period. The computation of shape is even simple compared with linear light case. We give results of shape recovery on real objects.
