Abstract

Photometric stereo has been successfully applied to many shape from shading tasks [1, 2, 3, 4]. With knowledge of the geometry of surrounding light sources and the surface reflectance properties of the object being viewed, photometric stereo can recover the local surface orientation of an object in view. The technique requires depth information from the scene in order to calculate the correct surface gradient. In this work I will demonstrate that it is possible to completely parameterise a restricted set of geometric surfaces without specifying any depth information from the scene. Objects are modelled as having a perfect Lambertian surface allowing a simple reflectance model whilst closely approximating many common surfaces.
