ABSTRACT 
Structure-typed cultural heritage, objects of preservation are positioned as one of very important heritage in national aspect, and its 
preservation of prototypical structure become influential against national development and natural disaster. From this reason, Digital 
Close Range Photogrammetry has recently been used diversely. Despite popular use, the measurement has limits to be unsuitable for 
photographing precisely cultural heritage situated at high a mountainous terrain or where people can not approach easily, high 
gigantic stone statues among the preserved structure-typed cultural heritage. In order to supplement the limits, when using the 
measurement, a camera tripod with 30m, a ladder truck and a shore should be equipped, which means additional equipment leads 
uneconomical waste of cost and time. 
In this vein, this study developed a device, in detail, used a RC Helicopter installed with CCD(Charge Coupled Device) video camera 
with easiness of control, safety, equipment, carrying, movement and approach, then checked images shot by wireless modem at real 
time and considered economical efficiency without re-photographing. Next, this paper digitized the images of nationally designated 
structure-typed cultural heritage, used materials about them restored as the third dimension in order to construct the integrated 
management-information system for cultural heritage. 
Through the above processes, this study can provide specific information on 3D images and 3D CAD sections of structured-typed 
cultural heritage for both public and specialists on the web. Moreover, it suggests the foundation to restore the damaged cultural 
heritage in the future by the aim of effective management and preservation for them. 
1. Introduction 
A variety of projects for cultivating the land are currently 
under way buoyed by the increased demand of infrastructures 
accompanied with the rapid economic growth and qualitative 
improvement of life. And, the global warming is due to the 
natural full-scale weather change phenomena such as El Nino 
and the greenhouse gases such as CO, or CFC happening all 
over the world from the late of twenty century, to which the 
natural disasters are gradually increasing. According to this, 
the cultural heritages, which are archeologically of great 
value, are damaged or destroyed by wind and weather, 
inflicting a big loss on the country. Thus, in order to prevent 
the archeological cultural heritages from developments of the 
land and from the natural disasters, the performance of the 
advanced projects is necessary to the original preservation of 
cultural heritages. And for the original preservation of 
cultural properties, the existing actual measurement has been 
largely used for observation, but in recent, Digital Close- 
Range Photogrammetry (DCRP) is being used for it. 
As DCRP can acquire an accurate 3D data from 2D data 
stored by a analysis of the stochastic images based on the 
reappearance of photographing conditions, it is having been 
wide application as a precise technique measuring digital data. 
Also, as DCRP can measure a photograph taken by camera 
minutely and repeatedly, it is largely applying to a spatial 
analysis such as engineering works structures including 
bridge and tunnel, building structures location, size and 
transformation, human technology, field investigating traffic 
accident as well as police and law sciences field, and roads 
present condition.(Henri v. George V, 1998; Younian Wang, 
1998; Frank A. van den Heuvel, 1998; Petros Patias, 2000; 
Nicola D' Apuzzo, 2000) 
Structure-typed cultural heritage, objects of preservation 
are positioned as one of very important heritage in national 
aspect, and its preservation of prototypical structure become 
influential against national development and natural disaster. 
From this reason, Digital Close Range Photogrammetry has 
recently been used diversely. Despite popular use, thc 
measurement has limits to be unsuitable for photographing 
precisely cultural heritage situated at high a mountainous 
terrain or where people can not approach easily, high gigantic 
stone statues among the preserved structure-typed cultural 
heritage. In order to supplement the limits, when using the 
measurement, a camera tripod with 30m, a ladder truck and 
a shore should be equipped, which means additional 
equipment leads uneconomical waste of cost and time. 
In this vein, this study developed a device, in detail, used 
a RC Helicopter installed with CCD(Charge Coupled Device) 
video camera with easiness of control, safety, equipment, 
carrying, movement and approach, then checked images shot 
by wireless modem at real time and considered economical 
efficiency without re-photographing. Next, this paper 
digitized the images of nationally designated structure-typed 
cultural heritage, used materials about them restored as the 
third dimension in order to construct the integrated 
management-information system for cultural heritage. 
Through the above processes, this study can provide 
specific information on 3D images and 3D CAD sections of 
structured-typed cultural heritage for both public and 
specialists on the web. Moreover, it suggests the foundation 
to restore the damaged cultural heritage in the future by the 
aim of effective management and preservation for them.
