Patent number: 7327897Abstract: Disclosed herein is a method of precisely correcting geometrically distorted satellite images. In order to correct a geometrically distorted satellite image, the position and attitude of a satellite must be accurately recognized. In this case, a correlation between the position and attitude values of the satellite exists, so accurate position and attitude values cannot be obtained. Therefore, the present invention accurately obtains position and attitude information of the satellite by separating variables having a high correlation to minimize the correlation between the position and attitude of the satellite and then calculating corresponding variables, and precisely corrects a geometrically distorted satellite image using the position and attitude information of the satellite.Type: GrantFiled: December 30, 2002Date of Patent: February 5, 2008Assignee: Korea Advanced Institute of Science and TechnologyInventors: Myung Jin Choi, Tae Jung Kim
