3-D Positioning by Adjustment of the Rational Polynomial Coefficients Data of IKONOS Satellite Image

IKONOS 위성영상 RPC 자료의 수정보완에 의한 3차원 위치결정

This paper presents on adjustment methods of the vendor-provided RPC(Rational Polynomial Coefficient) of GEO-level stereo images for the IKONOS satellite. RPC are adjusted with control points by the first-order polynomial and the block adjustment method in this study. As results, the maximum error of 3D ground coordinates by the adjusted RPC model did not exceed 4m. The block adjustment method is more stability than the first-order polynomial method.
