Abstract

Method for calibrating an optical recording device, the method comprises constructing a plurality of scenes so that, for each location of the first set of calibration locations, a calibration indicium of the set of indicia is located in a respective scene of the plurality of scenes at said each location; acquiring a plurality of images, so that each scene of the plurality of scenes is displayed in a respective image of the plurality of images; locating a plurality of calibration loci so that, for each location of the first set of calibration locations, a respective locus of the plurality of calibration loci is comprised in a respective image of the plurality of images; and calibrating the optical recording device by using the loci of the plurality of calibration loci as locations in the image plane of the projection onto the image plane of the first calibration view.
