Information presentation apparatus and information presentation method

An information presentation apparatus comprising:

• three-dimensional model data recording means in which three-dimensional model data of a photography object is recorded;
• projection means for projecting a marker whose three-dimensional position/posture relation with said photography object is known onto said photography object;
• image input means for inputting said photography object on which said marker is projected;
• position detection means for using the position of the marker in an image inputted by the image input means to detect a relative position relation of said photography object with said image input means;
• and
• display means for using the position of said photography object obtained by said position detection means to superpose and display the three-dimensional model data of said photography object in said three-dimensional model data recording means upon the image of said photography object inputted by said image input means so that the position of the image of said photography object coincides with the position of said three-dimensional model data.

An information presentation method comprising:

• a step of projecting a marker whose three-dimensional position/posture relation with a photography object is known upon the photography object;
• a step of inputting said photography object on which said marker is projected;
• a step of using a position of said marker in an inputted image to detect the position of said photography object;
• and
• a step of using the detected position of said photography object to superpose and display pre-recorded three-dimensional model data upon the image of said inputted photography object so that the position of the image of said photography object coincides with the position of said three-dimensional model data.
