Abstract
Disclosed is an image processing arrangement to determine camera parameters and make a three-dimensional shaped model of an object from a single frame picture image in an easy manner in an interactive mode. There are provided arrangements for designating perspective directional lines and at least two directional lines which are orthogonal to one of the directional lines. There are further provided arrangements for inputting feature information from an actual image in an interactive mode, for inputting a knowledge information concerning the feature information, for calculating camera parameters of the actual image from the aforesaid information, and for making a three-dimensional CG model data in reference to the camera parameters, the feature information of an image and a knowledge information concerning the aforesaid information. With such arrangements, it is possible to make a three-dimensional model easily from one actual image having unknown camera parameters while visually confirming a result.
