Abstract
A method, system and computer program for obtaining a digital model of an object. The method includes steps of (a) generating a low spatial resolution numerical representation of an object, such as a triangular mesh representation; (b) generating higher spatial resolution images of the object using a photometric subsystem, having a camera and a lighting source; and (c) computing normals maps using the low resolution numerical representation to estimate a distance from the camera to points on the object and to adjust relative light source intensities so as to correct for uncertainties in distances and light source intensities. A feature of this method is that the computed normals maps are made consistent over the object.
