Systematic Non-Linearity for Multiple Distributed Illumination Units for Time-of-Flight (PMD) Cameras

摘要

The non-linearity of phase and amplitude of time-of-flight cameras' measurements with a single, usually coaxial illumination unit has been discussed excessively in literature. This effect is calibrated using a number of different approaches (B-Splines, polynomial approximation or with infinite Fourier series). In this paper, this concept is extended to the calibration of multiple distributed illumination units used simultaneously.
