Title
An incremental procedure for the lateral calibration of a time-of-flight camera by one image of a flat surface
Author
Abstract
We present a simple and accurate procedure to calibrate the pinhole parameters of a Time-of-Flight camera: the principal point c=(u0,v0) , the focal length f and, if needed, the aspect ratio τ . Only one image of a flat surface is needed. Using the radial distances as provided by the Time-of-Flight principle, we reconstruct the pixel rows (or pixel columns) as collinear points in 3-space. Motivated by theoretical results, we claim that the correct values for u0 , v0 and f can be found by an incremental procedure. In case of unknown aspect ratio, some (but few) iterations are needed.
