More Information
Summary:A calibration method is for a photographic device that photographs an object through a transparent body. The calibration method includes: acquiring a first photographic image by photographing the object without interposing the transparent body; acquiring a second photographic image by photographing the object through the transparent body; calculating an absolute positional deviation that indicates a deviation in coordinates of an image of the object due to the transparent body based on coordinates of an image of the object on the first photographic image and coordinates of an image of the object on the second photographic image; calculating a correction parameter for calibrating the absolute positional deviation; and storing the correction parameter in the photographic device. L'invention concerne un procédé d'étalonnage qui est destiné à un dispositif photographique qui photographie un objet à travers un corps transparent. Le procédé d'étalonnage consiste à : acquérir une première image photographique en photographiant l'objet sans intercaler le corps transparent ; acquérir une seconde image photographique en photographiant l'objet à travers le corps transparent ; calculer un écart de position absolu qui indique une déviation dans les coordonnées d'une image de l'objet en raison du corps transparent sur la base des coordonnées d'une image de l'objet sur la première image photographique et des coordonnées d'une image de l'objet sur la seconde image photographique ; calculer un paramètre de correction permettant de calibrer l'écart de position absolu ; et stocker le paramètre de correction dans le dispositif photographique.
