Abstract
An image processing apparatus approximates a three-dimensional shape of a target object, acquired from an image of of the target object, by a quadric surface, applies a plane expansion process that expands the quadric surface into an expansion plane, to data of the image, computes corresponding points before and after the plane expansion process, and generates normalized data of the image from the corresponding points that are computed. The corresponding points are computed based on a point on a straight line of the expansion plane in contact with a point on the quadric surface and corresponding to a reference point on the target object, and an intersection point of an imaginary straight line, passing through the point on the straight line and extending in a direction of a first normal vector with respect to the straight line, and a quadratic curve of the quadric surface.
