Abstract
A method for modelling an imaging device including an image sensor and an optical system is disclosed. The optical system has an aperture iris diaphragm defining an entrance pupil of the optical system. For a given configuration of the imaging device the method includes estimating a set of characteristic intrinsic parameters of the imaging device, in which a first intrinsic parameter is representative of a distance between the image plane and a sensor conjugated plane conjugated to the image sensor with respect to the optical system; a second intrinsic parameter is representative of a distance between the sensor conjugated plane and the entrance pupil and a third intrinsic parameter is representative of a magnification of the optical system; determining first and second modelling data respectively as a function of the first and third intrinsic parameters and second and third intrinsic parameters; and establishing a model of the imaging device as a function of the second and third modelling data.
