Airborne Three-Linear CCD Sensor ADS40 Geometric Calibration

In the paper the self-calibration bundle block adjustment technique based on the additional parameters is applied to the airborne linear CCD sensor ADS40 geometric calibration. Upon the detailed investigation on the imaging error properties of the three linear CCD sensor, the suitable sensor calibration parameter model is built up, and then the self-calibration bundle block adjustment model for the calibration is set up. Finally the ADS40 data on the test field is used for the calibration experiments. Experimental results prove that the geometric calibration method is correct and effective, which can significantly improve the measuring accuracy and the reliability.
