应用实体建模方法判断树木自然倒向的研究

Research on Using Entity Modeling Methods to Determine the Natural Orientation of Trees

判断树木自然倒向是伐木过程中不可或缺的一环。对于从事森林采伐、营林抚育和园林绿化等工作的林业生产人员,准确判断树木自然倒向是实现安全伐木必须掌握的知识和技能。通过应用激光测距仪对自然生长的树木进行现场测量,获取树木树高、胸径等数据。然后,应用SolidWorks对树木进行3D实体建模,构建出与实物树木基本一致的虚拟树,计算虚拟树重心并确定其自然倒向。试验结果表明,该方法可以为安全伐木提供技术支持。

Judging the natural orientation of trees is an indispensable part of the logging process.For forestry production personnel engaged in forest logging,forest management,and landscaping,accurately determining the natural orientation of trees is a necessary knowledge and skill to achieve safe logging.By using a laser rangefinder to measure naturally growing trees on site,data such as tree height and diameter at breast height can be obtained.Then,SolidWorks is applied to 3D model the trees,construct a virtual tree that is basically consistent with the actual tree,calculate the center of gravity of the virtual tree,and determine its natural orientation.The experimental results indicate that this method can provide technical support for safe logging.
