ABSTRACT
This paper is about data acquisition by digital photogrammetry method for the preservation of cultural
assets. As the result of this study, precise digital
depth model could be developed on a personnel
computer. The model can be than kept together with the image data to be used as a recording
system for the preservation of cultural assets.
1. Introduction
There are many cultural assets in Korea, distributed
countrywide and most of them originated a long. time
ago, some dating back to more than a thousand years.
Besides having historic values, the architecture of these
structures can disclose cultural background of the
originating time.
But because of rapid industrialization as well as natural
hazards such as earthquakes, fires, and floods, most of
the structures are fragile to damage and. deterioration.
Digital photogrammetry, referred to as the 4th generation
phase of photogrammetry, processes digital data rather
than analog data used in analytical photogrammetry.
Digital photogrammetry began to be recognized in the
eighties and active research is still going on in this field.
The benefits of digital photogrammetry is automation and
Systematic management of the photogrammetry
procedures, preservation of data and easy reconstruction
of photogrammetric conditions. In this study digital
photogrammetry techniques were applied to acquire basic
data and to do various analysis and evaluation.
An experiment was carried out on the main stone statue
of Buddha which is inside the Suk-Gul-Am, one of the
oldest structures in East Asia. Also maps are generated
of Chum-Sung-Dae the oldest astronomical observatory.
Analysis of these structures based on acquired data such
as formative ratio of Suk-Gul-Am is also performed.
2. Digital Photogrammetry
Topographic maps are usually made from
stereophotographs using analytical plotter. Even in the
case of digital stereoscopic images, which can be get
from SPOT satellite, analytical plotter is usually used.
But, in this case, digital images at first must be
transformed to photographs on film or paper because
