    • Abstract
  • We propose a method for refining the RPCs.That is,refining the RPCs through eliminating systematic errors in the virtual grid.The empirical results show that the planimetric accuracy in image-space for QuickBird imagery reaches ±2.4 pixels after refining the RPCs by the proposed method.For SPOT-5 stereo imagery,the planimetric and height accuracy of the object stereo positioning are ±5.892 m and ±4.020 m,respectively.
