Abstract
Construction of a three dimensional model of an object based on images of the object being illuminated by different regions of a display in sequence. The images are obtained by a camera facing a direction relatively the same as the display, and the camera is at a relatively fixed position in relation to the object. Construction of the three dimensional model includes finding an estimate of a set of light source vectors representing the different illuminated regions of the display, and finding an estimate of the shape and albedo of the object based on the estimated set of light source vectors.
