Abstract:
1. An imaging apparatus comprising: a circular marker, having two semicircular portions of a first color area and a second color area separated by a center line, which indicates a position and angles for arranging an image of a virtual object in an image of a real space, an image acquiring means for acquiring an image of a real space including the marker; a calculating means for detecting an area of the marker from the image acquired by the image acquiring means, calculating center coordinates of the marker based on coordinates of tangents with the area of the marker in a horizontal direction and a vertical direction of the image acquired by the image acquiring means and calculating angles of the marker, when arranging a virtual object in the real space based on the area of the marker; and an imaging means for constructing an image of the virtual object virtually arranged in the real space by the position and the angles indicated by the marker based on the calculation results of the calculating means and the shape data of the virtual object.
