Impact of attitude measurement errors on laser footprints positioning accuracy

Abstract

In order to analyze the impact of attitude measurement errors (roll, pitch and yaw errors) on the positioning accuracy of laser footprints, the positioning principle of airborne Light Detection And Ranging (LiDAR) was analyzed and the transformation relationship between the attitude measurement errors and the positioning errors of laser footprints was deduced. Considering the actual complex terrain, three different terrains were simulated to analyze the influence of attitude measurement errors on the positioning accuracy of laser footprints. After simulating calculations, some conclusions can be obtained, such as the impact of the roll angle error on the positioning accuracy of laser footprints is the most significant, the impact of the yaw angle error is minimal. And the results of the study will offer a theory foundation for the study of the positioning accuracy of laser footprints and practical application.
