Abstract

The 3D laser scanner operates by measuring the distance from the sensor to the target and operates on the same principle as Electronic Distance Measuring (EDM). Recently, 3D laser scanning technology has been rapidly developed in line with the strongly increasing demand for 3D information acquisition. Therefore, it is now possible to more easily acquire geometric information of various objects existing in real space. In this study, we constructed geospatial information by using new equipment which integrated 3D laser scanner and total station, and we suggest the possibility of using new technology for geospatial information construction by comparing and analyzing with existing methods. In the study result, we demonstrated the efficiency of the geospatial information constructed by integration of 3D laser scanner and total station. The proposed method is expected to shorten the time required for data acquisition compared to the existing method using the existing total station. Furthermore, it is possible to use various methods such as cross section analysis and volume calculation using the acquired data. In the future, spatial information construction by integration of 3D laser scanner and total station will help improve work efficiency in related fields.

3D 레이저 스캐너는 센서로부터 목표물까지 거리를 측정하는 방식으로 작동되며, 광파거리 측정기와 동일한 원리로 작동된다. 최근 3차원 데이터의 수요 및 활용이 급격히 증가함에 따라 레이저 스캔 관련 기술이 빠르게 발달하고 있으며, 이로 인해 과거에 비해 공간상의 대상물에 대한 위치 정보를 쉽게 취득할 수 있게 되었다. 본 연구에서는 3D 레이저 스캐너와 토털스테이션을 통합한 새로운 장비를 활용하여 공간정보를 구축하고, 기존 작업방법과 비교 분석을 통해 공간정보 구축을 위한 새로운 기술의 활용 가능성을 제시하고자 하였다. 연구결과, 3D 레이저 스캐너와 토털스테이션 통합에 의한 공간정보 구축의 효율성을 제시할 수 있었다. 제안한 방법은 기존의 토털스테이션을 이용하는 방법보다 데이터 취득에 소요되는 시간을 단축시킬 수 있을 것으로 기대되며, 취득된 데이터를 이용한 단면도 생성, 체적산출 등 다양한 활용이 가능하였다. 향후 3D 레이저 스캐너와 토털스테이션 통합에 의한 공간정보 구축 방법은 관련분야의 작업 효율성 향상에 크게 기여할 것이다.
