After the identification of omission parts, stereo matching is
performed only about the omission parts, therefore 3D shape
data can be interpolated. Furthermore, color information is
copied from central projection image to simulated central
projection image. As the result of this process, colored ortho
projection image without omission parts can be obtained.
4. INTERPOLATED RESULT
Figure 6 is interpolated result by refind system. It can be
recognized that imaging for shadow areas occurring in hollow
areas on complicated relics or faint areas at the top of columnar
relics are successfully performed.

In addition, one of the remarkable points of the system used
high resolution cameras is its ability to obtain high quality
image. Figure 7 shows enlarged image for a part of ortho
projection image which were taken by 0.4 M pixel CCD
camera and 5.24M pixel amateur camera.
Figure 8 shows 3D model with high-resolution texture which
was obtained by the refined system.

5. CONCLUSION
The refined ortho imaging system for imaging shadow areas
occurring in hollow areas on complicated relics or faint areas at
the top of columnar relics and lack of image quality were
described. The remarkable points as additional results of the
system are its ability and 3D color model.
However, there is issue which need to be resolved before this
system may become more operational. This problem is human
intervention for camera calibration, and this process should be
simplified for further operational development of the system.
