Positioning Accuracy Analysis and Application for Worldview-1 Stereo Imagery
Keywords: WorldView-1, High resolution satellite, Stereo images, Positioning accuracy
Abstract. This article introduced the progress of processing the WorldView-1 satellite image by using the air triangulation method．And different adjustment models were used to improve the vendor provided RPC (Rational Polynomial Coefficients) accuracy. WorldVfew-1 images in Beijing are used to test the correction accuracy of these adjustment models．Results show that the systematic errors of RPC model can be eliminated using a small amount of control points. The planar RMSE can reach 1.6 pixels (0.9 meter)．
