Patent ID: 7057614

Claim:
An information display system comprising: an image input unit configured to input an image; a position information management unit configured to estimate position/orientation information of the image input unit in an object coordinate system, from the image input by the image input unit; a three-dimensional model data arranged in the object coordinate system; a dynamic deformation control unit configured to dynamically control the deformation of the three-dimensional model data; a two-dimensional projection image generating unit configured to generate, based on the position/orientation information of the image input unit estimated by the position information management unit, a two-dimensional projection image data in a view field of the image input unit for the three-dimensional model data deformation-controlled by the dynamic deformation control unit; and a superposed display unit configured to display, in superposed relation with the input image from the image input unit, the two-dimensional projection image data generated by the two-dimensional projection image generating unit.
