Zusammenfassung:	A positioning device of the present invention comprises: a moving information calculating unit; a vision unit; and a position calculating unit. The moving information calculating unit calculates moving information including a speed of a moving object. The vision unit photographs an edge of a building in a GPS shadow area. When moving object enters into the GPS shadow area, the position calculating unit obtains a first estimating position of the moving object from the moving information and obtains a second estimating position of the moving object from information of the vision unit to calculate a pseudo position of the moving object in the GPS shadow area by combining the first estimating position with the second estimating position. The present invention can calculate the pseudo position of the moving object in the GPS shadow area. 본 발명의 측위 장치는 이동체의 속도를 포함하는 이동정보를 계산하는 이동정보 산출부, GPS 음영 지역 내 건물의 엣지를 촬영하는 비전부, 및 이동체가 GPS 음영 지역에 진입하는 경우, 상기 이동정보로부터 이동체의 제1 추정 위치를 획득하고 상기 비전부의 정보로부터 이동체의 제2 추정 위치를 획득하여, 상기 제1 추정 위치와 제2 추정 위치를 결합하여 GPS 음영 지역 내의 이동체의 의사 위치를 계산하는 위치 산출부를 포함할 수 있다.
