The present invention provides a method for acquiring a hyperspectral image. The method comprises: (a) a step of setting, by a flight path setting module (220), the flight path of an unmanned aerial vehicle (100) by using a collection area; (b) a step of acquiring, by the unmanned aerial vehicle (100), hyperspectral information for each preset image unit through line scanning by using a hyperspectral sensor (140) while flying along the set flight path; (c) a step of correcting, by a geometry correction module (250), the geometry of the hyperspectral information acquired for each image unit by using position information of each pixel; and (d) a step of acquiring, by an image matching module (260), a hyperspectral image of the collection area by matching the hyperspectral information acquired for each image unit, on which the geometric correction has been performed. Therefore, the method can solve a problem for which the accuracy of image matching is reduced by the characteristics of line scanning of the hyperspectral sensor.

    본 발명은 (a) 비행경로 설정모듈(220)이, 수집영역을 이용하여 무인비행체(100)의 비행경로를 설정하는 단계; (b) 무인비행체(100)가, 상기 설정된 비행경로를 따라 비행하면서, 초분광 센서(140)를 이용하여, 라인 스캐닝을 통해, 기 설정된 영상 단위마다 초분광정보를 획득하는 단계; (c) 기하보정 수행모듈(250)이, 상기 각각의 영상 단위마다 획득된 초분광정보에 대하여 각 픽셀의 위치정보를 이용하여 기하보정을 수행하는 단계; 및 (d) 영상정합 수행모듈(260)이, 상기 기하보정이 수행된, 상기 각각의 영상 단위마다 획득된 초분광정보를 정합하여, 상기 수집영역의 초분광영상을 획득하는 단계를 포함하는, 초분광영상 획득 방법을 제공한다.
