Paper Abstract

Surfaces that are recovered by integrating slope estimates are prone to errors caused by discontinuities in the surface. We propose combining laser sectioning and photometric stereo (PS) to estimate surface shape. PS is used to estimate slope; laser lines are used to measure four height profiles. The slopes are integrated along paths that start from the laser height profiles and avoid discontinuities. The scheme is shown to mitigate the bias and surface discontinuity problems associated with PS.
