A system for measuring river topography by using a drone, and a method, according to an embodiment therefor, are disclosed. The river topography measurement system comprises: a mobile device, which has a LIDAR and a hyperspectral sensor mounted thereon, acquires distance information by using the LIDAR while flying over a river area including protected lowland and riverside land, and acquires a hyperspectral image by using the hyperspectral sensor; and a relay device for calculating two-dimensional planar river topography information about the river area as a result analyzed by receiving the distance information and the hyperspectral image, while moving along the river area according to the flight of the mobile device.
L'invention concerne un système de mesure de topographie de rivière à l'aide d'un drone, et un procédé, selon un mode de réalisation de celui-ci. Le système de mesure de topographie de rivière comprend les étapes suivantes : un dispositif mobile, qui possède un LIDAR et un capteur hyperspectral monté sur celui-ci, acquiert des informations de distance à l'aide du LIDAR tout en volant sur une zone de rivière comprenant un terrain de plaine et un terrain de rive protégés, et acquiert une image hyperspectrale à l'aide du capteur hyperspectral ; et un dispositif de relais pour calculer des informations de topographie de rivière plane bidimensionnelle concernant la zone de rivière en tant que résultat analysé par réception des informations de distance et de l'image hyperspectrale, tout en se déplaçant le long de la zone de rivière en fonction du vol du dispositif mobile.
