Reliable Estimates of Merchantable Timber Volume from Terrestrial Laser Scanning

Popis výsledku v původním jazyce

Simple and accurate determination of merchantable tree height is needed for accurate estimations of merchantable volume. Conventional field methods of forest inventory can lead to biased estimates of tree height and diameter, especially in complex forest structures. Terrestrial laser scanner (TLS) data can be used to determine merchantable height and diameter at different heights with high accuracy and detail. This study focuses on the use of the random sampling consensus method (RANSAC) for generating the length and diameter of logs to estimate merchantable volume at the tree level using Huber s formula. For this study, we used two plots, plot A contained deciduous trees and plot B consisted of conifers. Our results demonstrated that the TLS-based outputs for stem modelling using the RANSAC method performed very well with low bias (0,02 for deciduous and 0,01 for conifers) and a high degree of accuracy (97,73% for deciduous and 96,14% for conifers). We also found a high correlation between the propo
