摘要：The results of a multi-image photographic technique are compared with those obtained by close-range scanning of the same objectby a 3D colour laser scanner. The 3D representation achieved by the polynomial texture map (PTM) is compared with the extractionof normals from the same image set by photometric stereo. It is shown that the median of each of the X,Y,Z distributions of normalcomponents for a large number of 3-light combinations is a good estimator of the true normal at each point. Using an incisedEgyptian stone tablet, normals derived from these two techniques are compared with those generated by a 3D laser scanner. It isshown that the photometric stereo method produces the highest quality rendering of the surface
