Abstract
This paper presents a new digitizing technique which integrates a photometric stereo approach with the laser displacement sensors (LDS). The curvature at each element of the surface can be measured cost-effectively by the photometric stereo approach. Once the information of curvature on the surface is provided, the speed of LDS can be improved by digitizing the surface at selected points while the accuracy of digitization is still maintained. Experimental results are provided to verify the proposed method. >
