Flight obstacle extraction device, flight obstacle extraction method, and recording medium

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).

Description

technical field [0001] The present invention relates to an aerial obstacle extraction device, an aerial obstacle extraction method, and a recording medium, and more particularly, relates to an aerial obstacle extraction capable of extracting aerial obstacles according to the restricted surface and the height of buildings around the airport Device, aviation obstacle extraction method and recording medium. Background technique [0002] Around the airport, there are space restrictions in order to ensure the safety of the aircraft's navigation space. Such space restriction is called an airport restriction surface (hereinafter, simply referred to as "restriction surface"). The restricted surface is determined in order to prohibit the construction of tall buildings and the like in the vicinity of the airport because it will hinder the safe navigation of the aircraft if there are tall buildings near the airport. Therefore, the setting of buildings appearing on restricted surfaces...

AI Technical Summary

Problems solved by technology

In the case of a building that exceeds the restricted surface such as due to the builder's intention or negligence, etc., it is practically impossible to extract it as an aviation obstacle

That is, the aviation restricted surface inspection device 200 has insufficient problems as a device for judging whether the buildings around the airport interfere with the restricted surface in order to ensure the safety of the aircraft.
