An existing treatment of satellite imagery through ground control point (GCP) and digital elevation model (DEM) by using a reference point and a figure map for a three dimensional modeling of satellite imagery requires a variety of reference materials, and a great deal of time and cost. However, the present invention treats satellite imagery by using rational polynomial coefficient (RPC) including information about the position and the location of the satellite classified by the characteristic and the type of the satellite imagery; performs an image matching by extracting a common spot between two images for producing the satellite imagery into a three dimensional image; and performs a three dimensional modeling of the satellite image by using DEM obtained by a stereo image processing. According to the present invention, by shortening the time and the cost for producing an orthophotograph through reduction of the cost and the period for processing the satellite image, the utilization of satellite images, which has been increasing in security and private sectors, can be more improved. |
