6. CONCLUDING REMARKS
How to make an effective system in preservation of cultural
properties was described from photogrammetry and information
processing points of view.
To express structure drawings and images more intelligibly,
their three-dimensional solid figures (Isometric Drawings) and
CG were developed in a spatial three-dimension by using
Digital Photogrammetric Workstation. By using this system, it
becomes easy to obtain advice from cultural property experts
with a higher cultural appreciation.
In this paper, by combining huge shape information with
various drawing information for maintenance purpose, a
integrated management system by using CG and 3-dimensional
management system has been developed. By using the personal
computer, additional information can be inputted easily and
three-dimensional shape can be displayed quickly. Moreover,
the system has been applied to the Atomic bomb memorial
dome, and the possibility of three-dimensional preservation
management was introduced. As the results, conventional two-
dimensions maintenance management and repaired condition
records can be visualized into three-dimensions, therefore,
planning and consideration related to preservation activities
become easier.
The 3-dimensional GIS information management system used
in this research can be utilized in many fields as an effective
tool for preservation and maintenance management as well as
cultural property. By making damage condition and repair
history information feed back to a repair plan, a real time three-
dimensional visualization can be performed and a more rational
repair plan and construction can be achieved. In future, this
system can be greatly utilizable as a tool of observational
construction method to the maintenance management society.
