Claim One:
1. A method comprising: performing a system calibration for a one-dimensional coded light three-dimensional acquisition system by: using a coarse calibration to estimate system parameters; minimizing geometric reconstruction error including iterating until convergence of the following refinement sequence: fixing all parameters except a lens distortion model to determine camera distortion; fixing all parameters except a 2×4 projection matrix P P to determine a projector matrix P P ; fixing reconstructed points to determine an error function for an n-th view; fixing all parameters except parameters for a known planar calibration object and minimizing for a final bundle adjustment; refining R P and t P using the refinement sequence as the initial value and minimizing geometric error, where R P and t P are extrinsic rotation and translation parameters between the camera and projector coordinate system; and recovering K P , R P and t P from the projector matrix P P , where K P is a 2×3 intrinsic matrix.
