ABSTRACT: 
In order to grasp the safety and the reliability of structures in maintenance management of structures, such as cultural properties and 
buildings, it is effective to understand their visualized three-dimensional structures by recording their structural image with a remote 
control system. Practically, photogrammetry involves some barriers in the size of the structures and its swiftness in data collection. 
However, an integrated system in which enables to collect and manage three-dimensional structural shape and its damage 
information systematically, is important for maintenance management of structures. It is also necessary to develop a system with a 
three-dimensional GIS model to collect dimensional spatial data, to connect with various others digital information, and enables us 
to review the results whenever we want. Such three-dimensional visualization system can also be utilized for presentation purpose, 
besides can help engineers to make decision precisely and process work effectively. This system can be applied for civil engineering 
structures and buildings widely, here, the utilization on preservation of cultural properties is highlighted. In this paper, the utilization 
on the preservation management of the registered world heritage ‘Atomic bomb memorial dome’ is introduced. In order to manage 
the current structural condition in a three-dimensional coordinates precisely, photogrammetry was carried out, and a visualized 
system that can display each coordinate value was developed. Moreover, three-dimensional laser measurement system in which can 
capture targeted picture simultaneously was carried out. The possibility of application on preservation management system was 
examined by the comparison verification of each coordinate value. The development of innovative sensory technologies and their 
application possibilities are also introduced as well. 
1. INTRODUCTION 
utilizing newly developed sensory technology, such as 3D laser 
is introduced as well. 
Photogrammetry was carried in order to grasp the current state 
information in 3-dimensional coordinates of the Atomic bomb 
memorial dome in which has been protected as one of the world 
historical heritage. The fundamental information for delivering 
to next generations was created by the Hiroshima-city since 
1996. 
Unlike the usual building, the most part of dome's wall are 
curved surfaces in high intricacy. The total surface area of the 
dome is approximately to 4000 square meters. To extract the 
coordinates of outer and inner walls surface, marking fixed 
points and making photography plans were carried out carefully. 
Especially, photography of the central stairs room of this dome 
was performed by remote control equipment that can be 
photographed from the ground. In drawing measurement, the 
projection sides were set up so that they might become parallel 
to each wall's surface. The extracted coordinates of about 2 
million points were built as a solid model in the computer, and 
then elevation and sectional views were created. The 
coordinates of each point can simply be searched by newly

In this paper, how to apply photogrammetry and information 
processing technology in order to produce the effective system 
for recording and restoration of buildings is described.

atomic bomb is dropped on Hiroshima, and from that time the 
building is preserved as a symbol of the damage wrought by 
that bomb. It has been the UNESCO World Heritage since 1996.
