摘要

讨论了树木参数的测量，特别是树木的直径和位置，与森林采割机有关。除了距离扫描仪最近的点外，还使用基于特征边缘点的简单方法从激光扫描仪测量中确定直径。测量高度为距地面1.3 m。这项研究的数据是在松林中使用安装在移动ATV平台上的2D激光扫描仪收集的。树径计算的误差平均为4%。树木定位的评价是基于人工测量的森林参考数据。

Tree Measurement in Forest by 2D Laser Scanning

Measurement of tree parameters, particularly tree diameter and location, in connection to forest harvesters, is discussed. Diameters are determined from laser scanner measurements using a simple method based on edge points of a feature, in addition to the point with the shortest range to the scanner. The measurement height is equal to 1.3 m from the ground. The data for this research have been collected in a pine forest using a 2D laser scanner mounted on a mobile ATV platform. The error of the tree diameter calculations is 4% in average. The evaluation of the tree localization is based on manually measured reference data of the forest.
