Accuracy Assessment of Total Stem Volume Using Close-Range Sensing: Advances in Precision Forestry

Original language description

Accurate collection of dendrometric information is essential for improving decision confidence and supporting potential advances in forest management planning (FMP). Total stem volume is an important forest inventory parameter that requires high accuracy. Terrestrial laser scanning (TLS) has emerged as one of the most promising tools for automatically measuring total stem height and diameter at breast height (DBH) with very high detail. This study compares the accuracy of different methods for extracting the total stem height and DBH to estimate total stem volume from TLS data. Our results show that estimates of stem volume using the random sample consensus (RANSAC) and convex hull and H-TSP methods are more accurate (bias = 0,004 for RANSAC and bias = 0,009 for convex hull and H-TSP) than those using the circle fitting method (bias = 0,046). Furthermore, the RANSAC method had the best performance with the lowest bias and the highest percentage of accuracy (78,89%). The results of this study provide
