| 摘 要： | 利用三维激光扫描仪对树木进行扫描获取树点云数据,经过格式转换、分离、提取后,对树木各测量因子包括胸径、树高、树冠、材积量进行测定,并对测量方法进行分析与讨论。结果表明:树冠测定因子可以由于测量技术的提高,测定树冠的叶面积指数更能反映树冠的生理学意义;通过不规整三角网构建的多面体的计算的树干体积较平均断面积、中央断面积求树干材积更准确与便捷。 |
| 关 键 词： | 点云数据 测树因子 树冠 材积量 |

| Abstract: | In this paper,three-dimensional laser scanner has been used to scan trees to get point cloud data of trees.After format conversion,separation and extraction,the measurement and analysis are conducted to measure such factors as DBH,tree height,crown and timber volume.These factors can be calculated by point cloud data.Through experimental analysis,it can be drawn that with the improve of measurement techniques,the leaf area index of canopy is better to reflect the physiological significance of the crown;stem volume calculated by irregular polyhedron triangulation is more accurate and convenient than that by the average basal area and the central stem basal area in calculating volume. |
| Keywords: | point cloud data trees measure factors canopy volume |
