摘要
随着林业信息化的建设与发展,利用地面激光雷达快速获取树木点云数据,从中提取树木的结构参数(胸径,树高,材积等)已成为一种重要的林木测量手段。为了弥补国内在树木点云数据处理软件系统方面的空白,采用一系列树木结构参数提取算法,并结合计算机图形显示技术,设计并实现了一种三维树木点云数据处理软件系统。开发完成了树木点云数据的三维显示与旋转平移查看功能。拥有基本的点云数据处理功能,以及树木的胸径、树高、材积提取的功能。系统经过实验数据的验证,证明其拥有良好的性能,并可以快速准确地提取树木结构参数。
With the construction and development of forestry informatisation technology,it has become an important means of forest measurement that to employ terrestrial laser scanning to fast collect trees point cloud data and to extract from data the structural parameters（ diameter at breast height,tree height,volume,etc.） of trees. To fill the gap in terms of domestic software system for trees point cloud data processing,we designed and implemented a 3D trees point cloud data processing software system by using a series of tree structure parameter extraction algorithms and combining the computer graphics visualisation technology. The system achieves the functions of 3D display and rotating translational view of trees point cloud data. It has basic point cloud data processing functions,and the parameters extraction function for diameter at breast height（ DBH）,tree height and volume. After validating with experimental data,the system was proved to have good performance and could extract trees structural parameters quickly and accurately.
