Title:
METHOD FOR CONSTRUCTING AIR-OBSERVED TERRAIN DATA BY USING ROTARY WING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2015/005573
Kind Code:
A1
Abstract:
The present invention relates to a method for constructing air-observed terrain data by using a rotary wing structure, the method comprising: a flight route and photographing location setting step (S100) for calculating a flight route (P) and a photographing location (S) of a rotary wing structure (1) on the basis of a flight altitude and coordinates for dividing a predetermined area, which are inputted from a ground control center (40), and designating and setting a photographing starting location and a photographing ending location on the basis of the calculated flight route (P) and photographing location (S); a flight information receiving and storing step (S200) for transmitting, to the rotary wing structure (1), flight information set in the flight route and photographing location setting step (S100) so as to store the flight information in a flight control unit (40); an aerial photographing and image storing step (S300) for capturing a ground image by a photographing unit (30) of the rotary wing structure (1) and storing the ground image in a storage unit (23) when the rotary wing structure (1) arrives at the photographing location (S) while flying according to the flight information stored in the flight control unit (40) thereof; a photographing ending and returning step (S400) for ending photographing and returning to the ground when the rotary wing structure (1) arrives at the photographing ending location while repeatedly performing the aerial photographing and image storing step (S300); and an image verifying and synthesizing step (S500) of constructing, by a computer in the control center (40), terrain data by using ground images stored in the storage unit (23). According to the configuration described above, the present invention can easily and quickly construct high-quality terrain data.
