Abstract
The Army's High-Castle (HC) Airborne testbed 2021 flight campaign collected 3D point cloud data derived from a Geiger-mode LiDAR system. While the 3D data exhibited exceptional resolution of 3D ground targets, the horizontal resolution was 3-4 times worse than theoretical limits. The sources of resolution degradation remain a current research and calibration study. This paper presents a comprehensive virtual Kinematically Linked Model Framework that rigorously models the physical components of HC testbed hardware and the propagation of component errors on derived 3D point cloud products. In-depth examples of component errors and their impact on resolution degradation are presented.
