METHOD FOR CORRECTING AN IMAGE OF AT LEAST ONE OBJECT PRESENTED AT A DISTANCE IN FRONT OF AN IMAGING DEVICE AND ILLUMINATED BY A LIGHTING SYSTEM AND AN IMAGE PICKUP SYSTEM FOR IMPLEMENTING SAID METHOD
An image correction method includes: estimating a 3D model of an object as when an imaging device takes an image of the object; calculating the light intensity of each point of a simulated image as it would be taken by the imaging device, using the estimated 3D model of the object, a model of illumination of the object illuminated by a lighting system that illuminates the object, a model of reflection on a surface of the object, and a model of the imaging device, to obtain a simulated image of the object; and correcting the taken image by modifying the light intensity of each point on the taken image or on at least one area of interest of the taken image, according to the light intensity of the corresponding point in the simulated image or the respective light intensities of points adjacent to the corresponding point in the simulated image.
