Paper Abstract

The systematic errors caused by coordinate conversions in airborne lidar system under moving conditions belong to one of the main error sources to measurement accuracy. In order to reduce systematic errors and to attain high observation accuracy for three-dimensional imaging airborne lidar, the tracing of the systematic errors caused by coordinate conversions is realized. Besides, there has been substantial focus on both error analysis and development of error model for the airborne lidar system in this paper. On the basis of review of the coordinate conversion methods adopted in most airborne lidar systems, the Dopplerlet Transform analysis is applied to the systematic error mainly caused by coordinate conversions in airborne lidar for correction. And the effects on the observed results are evaluated. Finally, both the validity of the developed error model and the precision of the analytical method are verified.
