Abstract

This paper applies the photometric stereo technique for finding the shape and reflectance of an object using as illumination an extended rectangular light source. It derives the photometric stereo equations that are applicable and includes the geometry of the lights explicitly. The formulae are tested by finding the surface shape of a wedge with a known angle from four images. The results encourage confidence in the process.
