Claim Text:
1. A method for constructing air-observed terrain data by using a ground image obtained by a camera installed at a rotary wing structure, which is capable of performing a photographing operation while staying at a given position, the method comprising: a flight route and photographing location setting step of calculating a flight route and a photographing location of the rotary wing structure based on a flight altitude and coordinates for dividing a predetermined area, which are inputted from a ground control center; designating and setting step of designating and setting a photographing starting location and a photographing ending location based on the calculated flight route and photographing location at the ground control center; a flight information receiving and storing step of transmitting, from the ground control center to the rotary wing structure, flight information set in the flight route and photographing location setting step so as to store the flight information in a flight control unit; an aerial photographing and image storing step of capturing the ground image by a photographing unit of the rotary wing structure and storing the ground image in a storage unit when the rotary wing structure flies according to the flight information stored in the flight control unit thereof and arrives at the photographing location; a photographing ending and returning step of repeatedly performing the aerial photographing and image storing step, and ending the photographing and returning the rotary wing structure to the ground when the rotary wing structure arrives at the photographing ending location; and an image verifying and synthesizing step of constructing the terrain data in the computer of the ground control center using the ground images stored in the storage unit.
