Paper Abstract

In this paper, we propose a method for the structured-light field (SLF) 3D measurement, involving ray calibration and phase mapping. The ray calibration is carried out to determine each light ray with metric spatio-angular parameters. Base on the ray parametric equation, the phase mapping in the SLF is developed so that spatial coordinates could be directly mapped from phase-encoding information. Then, a calibration strategy is designed to determine the mapping coefficients for each light ray, achieving high-efficiency SLF 3D reconstruction.
