Summary:Computer implemented method for calibrating (216) an optical recording device (150), the optical recording device (150) being associated with a field of view and an image plane, by using at least a model panel (140), the model panel (140) comprising a set of calibration indicia (40-49), and a first calibration view, wherein the first calibration view comprises a first set of calibration locations (20-29) of the field of view, wherein the method comprises at least the steps of constructing (204, 207) at least a plurality of scenes so that, for each location of the first set of calibration locations (20-29), a calibration indicium of the set of indicia is located in a respective scene of the plurality of scenes at said each location, and wherein each scene of the plurality of scenes is constructed by translating the model panel (140) to a respective position with respect to the optical recording device (150); acquiring (205, 208) at least a plurality of images (920, 930), so that each scene of the plurality of scenes is displayed in a respective image of the plurality of images (920, 930); locating (206, 209) at least a plurality of calibration loci (60-69) so that, for each location of the first set of calibration locations (20-29), a respective locus of the plurality of calibration loci (60-69) is comprised in a respective image of the plurality of images (920, 930), said respective image displaying a respective calibration indicium and said respective calibration indicium being located at said each location and being displayed in said respective locus; and calibrating (216) the optical recording device (150) by using at least the loci of the plurality of calibration loci (60-69) as locations in the image plane of the projection onto the image plane of the first calibration view.
