지상라이다에 의한 건축문화재 역설계의 정확도 분석

Abstract

The primary purpose of this research was to acquire the 3 dimensional data for architectural heritage utilizing Terrestrial LiDAR survey and produce the reverse design map. In addition, authors tried to suggest the applicability of Terrestrial LiDAR survey in the field of architectural heritage preservation by comparing the accuracy of the reverse design map and that of the existing map which was produced by using current surveying method. Our study results showed that there was a little difference between the reverse design map and the existing map, which was within the range of an error tolerance. In terms of visualizing architectural heritage, the reverse design map seemed to be closer to the reality. It was difficult to compare the efficiency of two maps because there were not any detailed descriptions for precise actual survey methods. However, the Terrestrial LiDAR survey was turned out to be more time-efficient than the existing survey method. It was concluded that the reverse design of architectural heritage based on the Terrestrial LiDAR survey results seemed to have lots of applicability in the field of heritage preservation.
