Abstract

We present a method of aspheric surface reconstruction from the curvature data along two orthogonal directions. The curvature is an intrinsic property of the artifact, which does not depend on the positioning error of a measuring sensor. In this paper, we showed that the curvature method is suitable for aspheric surface reconstruction along one direction and expanded this algorithm to two directions. Computer simulations were undertaken to explore the possibility of three-dimensional surface reconstruction. The simulation results and the position error diagnosis showed that the curvature method is robust against various positioning errors.
