Abstract

Recent construction in the field of 3D aversion is increasing interest in automation. This study is results about survey of the coastal landfill using automatic VRS-GPS surveying system. GPS is made with GRXI and SHC250 controller. Automatic surveying system is composed of DPS module, geomagnetism sensor, bluetooth, gimbals, IMU, etc and enables an automatic driving via entered into a route of position. The developed auto surveying system has installed the front and camera for vertical axis and can grasp situation of surveying with smartphone in real time. The comparative result between surveyed result with repetition method auto VRS-GPS surveying system observed surveyed result with VRS-RTK has shown that average error of x-axis is 0.009m, average error of y-axis, 0.010m and average error of height, 0.002m. This possibility was confirmed that field application.

최근 건설현장에서는 3D 기피 현상으로 자동화에 대한 관심이 증대되고 있다. 본 연구는 개발된 VRS-GPS 기반 자동 측위시스템으로 해안매립지를 측량한 결과에 관한 연구이다. 자동측위시스템에 설치된 GPS는 GRX1 수신기와 SHC250 컨트롤러를 사용하였다. 자동측위시스템은 DSP모듈, 지자기센서, 블루투스, 짐벌, IMU등으로 구성되어 있으며, 입력된 위치경로로 자동주행이 가능하도록 하였다. 개발된 GPS 자동측위시스템은 전방과 구심점 관측 카메라를 설치하여 측량상황을 스마트폰으로 실시간으로 파악 할 수 있도록 하였다. 개발된 자동측위시스템을 건설현장에 적용하여 실험한 결과 평균제곱근오차는 X축에서 0.009m, Y측에서 0.010m, 높이는 0.002m로 나타났으며, 현장적용 가능성이 있음을 확인하였다.
