description The present invention relates to a map generation method and to an image-based positioning system which uses the same. According to the present invention, the image-based positioning map generation method includes the steps of: specifying the pose of a virtual camera using 3D model data based on a video photographing the outdoor space from the air; rendering an image of the outdoor space viewed from the virtual camera using the pose of the virtual camera and the 3D model data; and generating a feature map using the rendered image and the pose of the virtual camera. 본 발명은 맵 생성 방법 및 이를 이용한 이미지 기반 측위 시스템에 관한 것이다. 본 발명에 따른 이미지 기반 측위용 맵 생성 방법은, 항공에서 실외 공간을 촬영한 영상에 근거한 3차원 모델 데이터를 이용하여 가상 카메라의 포즈를 특정하는 단계와, 상기 가상 카메라의 포즈와 상기 3차원 모델 데이터를 이용하여 상기 가상 카메라에서 바라보는 상기 실외 공간에 대한 이미지를 렌더링하는 단계, 및 상기 렌더링된 이미지와 상기 가상 카메라의 포즈를 이용하여 특징점 맵을 생성하는 단계를 포함한다.
