Reconstruction of 3D models from specular motion using circular lights

This paper generalizes a shape recovery method for specular surfaces. We have use linear lights that generate planes of ray to highlight a rotating object so that its specular surfaces are computed from continuous images. By setting lights properly, shape at each rotation plane can be measured and a 3D graphics model can be subsequently reconstructed. In this paper, we extend the lights used to circular ones to produce cones of ray. Under such illuminations, all surface points with different normals are highlighted in a rotation period. The computation of shape is simpler than compared with the linear light case. We give results of shape recovery on real objects.
