Abstract

The error sources of airborne laser measurement device which mainly include laser beam misalignment with respect to scanning mirror, clock error, scanner error and scanner torsion are discussed, and their effects to airborne LIDAR(Light Detection and Ranging)position accuracy are analyzed. Specially, laser beam misalignment's influences to LIDAR scanning line distortion and positioning accuracy are analyzed in detail quantitatively and qualitatively for oscillating scanner. The analysis demonstrates that laser beam misalignment influences the scanning line distortion and positioning accuracy more and more with the increasing height and scanning angle and can't be eliminated by common calibration methods but by the calibration method in factory for it is related to other error sources.
