Boresight Misalignment Calibration of Airborne Laser Scanning System
Abstract:Boresight misalignment of airborne laser scanning system and its effect on the precision of the laser points. A calibration method based on overlapping strip which doesn’t need ground control points is developed, and then a corresponding function model and the flow chart of the calibration are established. Then the method of math is discussed. And at last by this method, some practice data is computed to get the boresight misalignment error.
Keywords: ALS boresight misalignment overlapping strip calibration matching
