Title:
FLIGHT OBSTACLE EXTRACTION DEVICE, FLIGHT OBSTACLE EXTRACTION METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2010/095529
Kind Code:
A1
Abstract:
Provided is a flight obstacle extraction device, a flight obstacle extraction method, and a recording medium which attain the detailed extraction of a flight obstacle with less man-hours. An altitude information acquisition unit (20) receives a plurality of images of a predetermined area captured from a plurality of different positions, and generates digital surface layer model data expressing the surface layer of the predetermined area with three-dimensional coordinates. An obstacle candidate computation unit (50), on the basis of the generated digital surface layer model data, extracts the candidates of the flight obstacle which may conflict with a flight restriction surface from among the images. A flight obstacle determination unit (60) detects the flight obstacle conflicting with the flight restriction surface from among the candidates of the flight obstacle extracted by the obstacle candidate computation unit (50).
