3-DIMENSIONAL GROUND COORDINATES DETERMINATION ACCURACY ANALYSIS BASED ON STEREO IMAGING ANGLE IN KOMPSAT-3A

摘要

In this paper, we present three-dimensional ground coordinates determination accuracy in stereo images taken in single-pass stereo images and multi-pass stereo images of KOMPSAT-3A. The ground control points needed for the computed 3D ground coordinate accuracy evaluation were GPS survey results. Radiometric and Spatial correction such as de-nosing, histogram enhancement and MTFC processing was processed to improve the interpretation image point according to the ground control point in the stereoscopic image. The determination of three-dimensional coordinates using the RPC was evaluated for accuracy using the relative orientation and the absolute orientation using the Socket Set S/W.
