International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B-YF. Istanbul 2004 3.4 Estimation of Shrine Size Utilizing photo and ground distance of the height and width for the front entrance gate, the depth distance to the center of both left and right side entrance gates are computed as figure 3-4, and the depth distance to the center of the shrine is estimated as the depth distance to the center of both left and right side entrance gates. As the results, diameter of the shrine is estimated as 35.4m. On the other hand, in order to compute the height of shrine, photo coordinate for the center of the shrine are requested. Therefore, oval general form are used to compute the photo coordinate for the center of the shrine since the circle on a real space is expressed as an oval on the picture, and a quadrangle diagonal intersection that encloses the oval become center of a circle. However, an oval center is not projected to center of a circle in the perspective projection. Then, in order to compute a center of circle using oval general form, major axis (a), minor axis (5), and center coordinates (0;) are requested. The diagonal intersection means a point projected as center of circle (0,) in figure 3-5, and 28.2m is computed as the height of the shrine. Furthermore, height of the eye point is computed as 3.3m from the difference of photo coordinates in y direction, and exposure position is also estimated as (0, 0, 0). | .

And A (X4, Y4, Zu) and B (Xs, Ya, Zp) respectively in Figure 3-6. The depth distance to the plane including point 4 is computed by Eq.(2) since the horizontal line have the same value with the height of eye point, therefore X, and Y, is computed by Eqs (3).

Similarly, 3D coordinate for the other objects are computed by the same procedures, and the height of right and left buildings are about 20m.
