Paper Abstract

A Monte Carlo ray tracing simulation of LiDAR propagation has been expanded to 3 dimensions, and makes use of the high-fidelity tree voxel model VoxLAD for realistic simulation of a single tree canopy. The VoxLAD model uses terrestrial LiDAR scanner data to determine Leaf Area Density (LAD) measurements for small volume voxels (~5 – 20 cm side length). The LAD measurement, along with material surface normal orientation information, is used within the Monte Carlo LiDAR propagation model to determine the probability of LiDAR energy being absorbed, transmitted or reflected at each voxel location, and the direction of scattering should an interaction occur. The high spatial fidelity of the VoxLAD models enables simulation of small-footprint LiDAR systems. Results are presented demonstrating incorporation of the VoxLAD model for realistic tree canopy simulation, and the full-waveform simulation capability of the Monte Carlo LiDAR code.
