    • Abstract
  • Boresight misalignment between a hyperspectral sensor and intergrated POS system is a key error source in image direct georeferecing(DG).Due to the poor intensity of tie/pass points nets of a nadir push-broom hyperspectral image,a rigorous bundle adjustment cannot be implemented for calibration.To solve this problem,this paper develops a simple boresight misalignment and position offset bundle adjustment calibration model using the exterior orientation elements solved by POS system with only systematic errors.Test results showed that this calibration model is sound and effective.The direct georeferencing precision with this calibration is improved significantly,with a standard deviation of approximately 1.4m(about 4 pixels) at planimetry and 4.4m(about 13 pixels) at the height in the test area.
