Abstract:
1. An image processing apparatus, comprising: an image input unit which inputs an image of a target object; a storage unit which stores information representing a shape of a three-dimensional model and three-dimensional positions of a plurality of reference feature points on the three-dimensional model; an extraction unit which extracts a plurality of feature points, which relate to the target object and correspond to the plurality of reference feature points, from the input image; a setting unit which sets target areas, related to the reference feature points, on the three-dimensional model; a calculation unit which, based on the extracted feature points and the reference feature points relating to the target areas, calculates a correspondence relationship between two-dimensional positions of the input image and three-dimensional positions of the target areas, for each target area; and a determination unit which, based on the correspondence relationship between the target areas and the input image, determines a correspondence relationship between three-dimensional positions of the three-dimensional model, which correspond to the target areas, and the two-dimensional position of the input image.
