Assessment of Stem Volume on Plots Using Terrestrial Laser Scanner: A Precision Forestry Application

Popis výsledku v původním jazyce

Timber volume is an important asset, not only as an ecological component, but also as a key source of present and future revenues, which requires precise estimates. We used the Trimble TX8 survey-grade terrestrial laser scanner (TLS) to create a detailed 3D point cloud for extracting total tree height and diameter at breast height (1,3 m, DBH). We compared two different methods to accurately estimate total tree heights: the first method was based on a modified version of the local maxima algorithm for treetop detection, H-TTD, and for the second method we used the centers of stem cross-sections at stump height (30 cm), H-TSP. DBH was estimated by a computationally robust algebraic circle-fitting algorithm through hierarchical cluster analysis (HCA). This study aimed to assess the accuracy of these descriptors for evaluating total stem volume by comparing the results with the reference tree measurements. The difference between the estimated total stem volume from H-TTD and measured stems was 2,732 m(3
