A method for producing a 3D map by using a plurality of aerial photograph images is provided to easily detect features on the ground, which vary in real time, produce a high-accuracy map, and simultaneously perform measurement of the features over a wide area. An image having a predetermined distance from an arbitrary ground region is acquired. An error rate is calculated by using the acquired image, and distortion of the image is corrected(S202). Information about a distance between an arbitrary feature on the ground and another feature is calculated by using triangulation(S203). 3D stereoscopic data of a corresponding feature is acquired(S204). A 2D or 3D image are acquired through the distortion correction, the distance information and 3D stereoscopic data(S205). A map is produced by using the acquired image(S206). |
