HOUSE COLLAPSE AREA EXTRACTION SYSTEM, METHOD OF EXTRACTING HOUSE COLLAPSE AREA, AND HOUSE COLLAPSE AREA EXTRACTION PROGRAM

摘要

PPROBLEM TO BE SOLVED: To extract a house collapse area with ideal precision by only an aerial image photographed after occurrence of an earthquake. PSOLUTION: A storage device 6 stores spectrum information on terrestrial objects such as a collapse house, a non-collapse house, and vegetation, appearing in the aerial image in advance. An arithmetic processing unit 4 divides the aerial image into a plurality of types of object areas corresponding to the terrestrial objects, based on the spectrum information by an area partitioning means 20. Further, a texture analysis means 24 extracts a house collapse area corresponding to a collapse house from the object area, based on the texture of the object area. PCOPYRIGHT: (C)2011,JPO&INPIT
