Outline of Final Research Achievements

In order to acquire 3D information for reconstruction of vanished historical structure, efficient measurement method by using smartphone and grasp of 3D shape of such structure was attempted by using an ancient picture. This kind of method was applied for an ancient picture of the Old Imperial Theater. The Old Imperial Theater in the picture is constituted by two-point perspective. Therefore, estimated value of focal length of camera, length of camera to the Old Imperial Theater and some parameters were calculated by estimation of field angle, using body height as an index of length and some geometrical information. Consequently, 3D coordinate of 120 measurement points on the surface of the Old Imperial Theater were calculated respectively, and 3DCG modeling of the Old Imperial Theater was realized.
