Abstract

In this paper, we describe an outdoor augmented reality system using GPS tracking for position and attitude information. The system consist of a remote mobile operation unit and a ground operation unit. The remote mobile operation unit includes a real-time image acquiring device, a GPS tracking device, and a wireless data transceiver; the ground operation unit includes a wireless transceiver, a virtual image generating device, and an image superimposing device. The GPS tracking device for measurement of position and attitude of the remote mobile operation unit was designed by TANS Vector and RT-20 for DGPS. The wireless data transceiver was for data transmission between the remote mobile operation unit and the ground operation unit. After the remote mobile operation unit was installed on a vehicle and a helicopter, the system was evaluated to verify its validity in actual applications. It was found that the implemented system could be used for obtaining real-time remote information such as construction simulation, tour guide, broadcasting, disaster observation, or military purpose.

본 논문에서는 GPS를 사용하여 위치와 자세 트래킹 정보를 이용하는 옥외용 증강현실 시스템을 구현하였다. 본 시스템은 이동 운용국과 지상 운용국으로 구성하였고, 이동 운용국은 실시간 영상 획득 장치, GPS 트래킹 장치와 무선 데이터 송수신기로 구성하였다. 지상 운용국은 무선 송수신기, 가상 영상 발생 장치와 영상 합성 장치로 구성하였다. 영상 획득 장치가 부착된 이동 운용국의 위치와 자세를 측정하는 GPS 트래킹 장치는 TANS Vector와 RT-20으로 DGPS을 이용하도록 설계하였고, 무선 데이터 송수신기는 이동 운용국과 지상 운용국간의 데이터 전송을 위하여 이용하였다. 차량과 헬리콥터에 구현한 시스템을 장착하여 평가한 결과 건축 시뮬레이션과 방송, 여행지 안내, 무인정찰기, 유${\cdot}$무인 항공기에서의 항법 지원과 능동적인 정보수집, 재해 관찰 등과 같은 분야에 적용할 수 있음을 알 수 있었다.
