Abstract

We propose a method to regenerate and correct Rational Polynomial Coefficients (RPCs) using KOMPSAT-3A imagery. Physical sensor model of KOMPSAT-3A and virtual grid over the target area were used to estimate the new RPCs. Three different image correction models (image coordinate translation model, shift and drift model, and affine transformation model) were used to remove image space error. We tested our method in Seoul and Goheung area. When using un-corrected new RPCs, the results showed a 20-30 pixel error. After applying image correction models, the error reduced to 1.8 to 5.5 pixels. The expected error map was generated from the error propagation analysis using Gauss-Markov Model.
