Abstract
There is provided a system for detecting a shape change of a building based upon an aerial photograph taken by an airplane. The system can process the aerial photograph without waiting for the airplane to land. On the airplane, edges are extracted directly from a central projected photographed image to be transmitted wirelessly to a ground station. This ground station extracts segments from the edges to thereby determine a shape of the building in the photographed image. On the other hand, the ground station generates a projected image of the building, which is obtained by central projecting existing three-dimensional data from a flying position of the airplane, and matches the projected image and the shape of the building obtained from the photographed image. According to a similarity between the two through the matching, it is decided whether or not the shape of the building has changed from the time of registration of the existing three-dimensional data.
