Abstract
This paper presents a novel strategy for rapid reconstruction of 3d surfaces based on 2d gradient directions. I.e., this method does not use triangulation for range data acquisition, but rather computes surface normals. These normals are 2d integrated and thus yield the desired surface coordinates; in addition they can be used to compute robust 3d features of free form surfaces. The reconstruction can be realized with uncalibrated systems by means of very fast and simple table look-up operations with moderate accuracy, or with calibrated systems with superior precision.
