Paper Abstract
With the development of increasingly advanced airborne sensing systems, there is a growing need to support
sensor system design, modeling, and product-algorithm development with explicit 3D structural ground truth
commensurate to the scale of acquisition. Terrestrial laser scanning is one such technique which could provide
this structural information. Commercial instrumentation to suit this purpose has existed for some time now, but
cost can be a prohibitive barrier for some applications. As such we recently developed a unique laser scanning
system from readily-available components, supporting low cost, highly portable, and rapid measurement of
below-canopy 3D forest structure. Tools were developed to automatically reconstruct tree stem models as an
initial step towards virtual forest scene generation. The objective of this paper is to assess the potential of this
hardware/algorithm suite to reconstruct 3D stem information for a single scan of a New England hardwood forest
site. Detailed tree stem structure (e.g., taper, sweep, and lean) is recovered for trees of varying diameter, species,
and range from the sensor. Absolute stem diameter retrieval accuracy is 12.5%, with a 4.5% overestimation bias
likely due to the LiDAR beam divergence.
