3차원 지적 구축을 위한 지상레이저측량의 적용에 관한 연구 : 건물 점군 객체 데이터의 정합 정확도 분석을 중심으로 = A Study on the Application of Terrestrial Laser Surveying for Building 3D Cadastre : Focusing on Accuracy Analysis on Matching of Building Point Cloud

다국어 초록 (Multilingual Abstract)

In this study, three-dimensional buildings with ground laser measurement point cloud data by applying various methods to acquire and to evaluate the accuracy of analysis.
After selecting the most accurate way to match, and TS measurement methods to verify its performance in 3D building was to present the possibility of applying.
Research results are as follows:
3D laser surveying and land surveying to perform a theoretical study, research, Cheongju City, residential development in the target areas are commercial areas in the district survey, conducted some experiments. Experimental observation methods were divided into two.
The first point to base above sea level value calculated using the reference point for the integrated GPS-Leveling surveys were performed.
And by the base-point altitude values ​​are used today in Traverse way, each target in a way to get a building point cloud data by matching it looked.
Results obtained for the data analysis,
The total value of the base points above the sea level stations by five points if you compare the value of Orthometric Heights average error of approximately 0.005m showed a very good show.
Matching method based on error type and a comparison of the average error of Traverse way 0.005m, the average error of the target method 0.011m, 0.007m identify point matching approach appears to be due to Traverse matching method showed the highest accuracy.
Match the highest accuracy of the methods presented by Traverse matching method selected and TS measurements, it looked way to verify the accuracy.
Verification of the value of a flat position and the height of the building want to verify with the analysis centered on the top of the corner points of the point total of 12 check points were selected.
Obtained by surveying a total of 12 points for the checkpoint point cloud data extracted from the building value, X, Y, Z coordinate values ​​and comparative analysis, X coordinates of the RMSE of ±0.0328m, Y coordinates of the RMSE appeared in the ±0.0363m altitude, the ±0.0489m RMSE values ​​appear as a way matched by Traverse manner when compared with the survey results are analyzed that there are significant differences.
Based on the results of this study pointed out three-dimensional look to build a ground laser point cloud data acquired by building surveyors and building trails in a manner depicting the bus: If you register in-depth coverage in terms of accuracy showed that the possibility.
However, as in this study selected a study area wide basis of the limitations that the selection did not verify the accuracy of matching as many points have not determined it is highly marginal.
Therefore, in building a real three-dimensional methodology of this study in order to be applied over a wide area is needed for the experiment and verification methodology.
