According to an embodiment, disclosed are a system for surveying river topography using a drone and a method thereof. The system for surveying river topography comprises: a moving device on which a lidar and a hyperspectral sensor are mounted, and which obtains distance information by using the lidar while flying over a river region including inland and riverside land, and obtains a hyperspectral image by using the hyperspectral sensor; and a relaying device which calculates two dimensional planar river topography information on the river region by a result of an analysis of the received distance information and hyperspectral image while moving along the river region following a flight of the moving device.
실시예에 의한 드론을 이용하여 하천 지형을 측량하기 위한 시스템 및 그 방법이 개시된다. 상기 하천 지형 측량 시스템은 라이다, 초분광 센서가 장착되고, 제내지와 제외지를 포함한 하천 영역을 비행하면서 상기 라이다를 이용하여 거리 정보를 획득하고, 상기 초분광 센서를 이용하여 초분광 영상을 획득하는 이동 장치; 및 상기 이동 장치의 비행에 따라 상기 하천 영역을 따라 이동하면서, 상기 거리 정보와 상기 초분광 영상을 제공받아 분석한 결과로 상기 하천 영역에 대한 2차원 면형 하천 지형 정보를 산출하는 중계 장치를 포함한다.
