地面激光扫描（TLS）已被证明是一种很有前途的技术，用于准确的森林资源调查的样地。应用TLS的优点是可以提高现场测量的精度和效率。此外，TLS数据有可能提供比目前普遍接受和使用的更多的树参数。本文讨论了用TLS实现股骨柄曲线的自动测量。实验中使用了一棵松树和一棵云杉。将从点云估计的茎曲线与现场测量进行比较。实验表明，单扫描点云和合并点云的茎曲线估计具有可比性。该结果表明TLS数据具有自动估计股骨柄曲线的潜力。
Terrestrial laser scanning (TLS) has been shown to be a promising technology for the accurate forest inventory on the sample plots. The advantages of applying TLS can be improving the accuracy and efficiency of the field measurements. In addition, TLS data have the possibility to provide more tree parameters than what are commonly accepted and employed at the moment. This paper discusses the automatic measurement of the stem curve using TLS. A pine and a spruce were used in the experiment. The stem curve estimated from point cloud was compared to the field measurements. The experiment shows that the estimation of the stem curve from single-scan and merged point clouds are comparable to each other. This result indicates that TLS data has the potential to automatically estimate the stem curve.
