Abstract

A model of a camera and a projector, accounting for the inherent geometric distortions of devices, is presented. The model includes coordinates of an optical center for the device and matrices with the values and the coordinates of the individual image pixels, considered in a plane at a given distance from the optical center and perpendicular to the optical axis of the device. The parameters of the model are determined experimentally. The model can successfully be used for the purposes of computer vision.
