Abstract
The authors have been concentrating on developing a real-time ortho imaging, drawing and modeling system for a recording system of relics using a CCD camera and line lasers. There are still, however, some issues which need to be resolved before this system may become operational. These problems include imaging for shadow areas occurring in hollow areas on complicated relics or faint areas at the top of columnar relics and lack of an exquisiteness for an edged image for a drawing.
This paper describes an imaging approach for these shadow and faint areas synthesizing an ortho and a central projection image which are taken using a color CCD camera. The most remarkable points of this approach are its ability to obtain a color ortho projection image and a color 3D model. As for further additional results of this system, visualization of relics from several view points can be achieved on the computer using an animation technique. Some virtual archeological examples are demonstrated in this paper.
