Information presentation apparatus and information presentation method

摘要

An information presentation apparatus comprises a three-dimensional model data recording apparatus. A projection apparatus projects a marker whose three-dimensional position/posture relation with a photography object is known onto the photography object. An image input apparatus inputs the photography object on which the marker is projected. A position detection apparatus uses the position of the marker in an image to detect a relative position relation between the photography object and the image input apparatus. A display apparatus uses the position of the photography object to superpose and display three-dimensional model data of the photography object upon the image of the photography object so that the position of the image of the photography object coincides with the position of the three-dimensional model data.
