FLIGHT OBSTACLE EXTRACTION DEVICE, FLIGHT OBSTACLE EXTRACTION METHOD, AND RECORDING MEDIUM |
摘要 |
Provided is a flight obstacle extraction device, a flight obstacle extraction method, and a recording medium which attain the detailed extraction of flight obstacles with fewer man-hours. An altitude information acquisition unit (20) receives a plurality of images imaging a predetermined area from a plurality of different positions, and generates digital surface model data expressing the surface of the given area with three-dimensional coordinates. An obstacle candidate computation unit (50), on the basis of generated digital surface model data, extracts candidates for flight obstacles which may conflict with a flight restriction surface from the images. A flight obstacle determination unit (60) detects flight obstacles conflicting with the flight restriction surface from among the candidates for flight obstacles extracted by the obstacle candidate computation unit (50). s for flight obstacles. |
