Abstract: In the paper the self-calibration bundle block adjustment technique based on the additional parameters is applied to the airborne linear CCD sensor geometric calibration. Taking the ADS40 sensor for example，the integrated sensor imaging relationship is analyzed firstly, and then the GPS observations model, the IMU misalignment angle model and the self-calibration bundle block adjustment model for the calibration are set up. Upon the detailed investigation on the imaging error properties, the suitable sensor calibration parameter model is built 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.
