Camera calibration by multiplexed phase encoding of coordinate information
What's it about?
A camera calibration method based on the principle of phase encoding and coordinate transformation is proposed. First, we use the coordinate reference frame encoded in a crossed grating. Then, the coordinate transformation induced by the imaging is exploited to estimate the intrinsic and extrinsic camera parameters. Thus, a robust and noniterative estimation scheme is obtained. The proposed method could be used to calibrate fringe-projection systems.
