可穿戴式树木测高帽的研制与试验

Experiment on Wearable Tree-Height Dendrometer

  • 摘要: 针对现有的林木测高理论和测量技术的局限性,本研究研制了一种可穿戴式树木测高帽,实现了树高和相 对坐标的测量。该设备以单片机、九轴传感器、红外测距模块等主要硬件为基础,通过测量距离、倾角和磁方位 角3 个参数,基于三角函数原理,嵌入操作软件,实现树体高度、相对坐标和冠幅的数字化、一体化精确测量。 以四蕊朴Celtis tetrandra 为测量树种,分别以不同距离(3 ~ 17 m)和树干不同高度(10 m 距离,5.01 ~ 0.90 m) 为测量对象,以鱼竿+皮尺为树高测量理论真值,将可穿戴式树木测高帽、手持激光测距仪和罗盘仪进行测量比较 试验;以32 株四蕊朴干为测量对象,以罗盘仪为方位角测量理论真值,与测高帽比较测量;以同一株滇朴为测量 树种,分别以不同距离(0.94 ~ 20.74 m)为测量对象,以皮尺为水平距离测量理论真值,分别以测高帽和手持激 光测距仪比较测量。结果表明,在树高、方位角和水平距离测量时,可穿戴式树木测高帽的准确度和中误差优于 其他两种测量方式。

     

    Abstract: Presentation was made on wearable tree-height dendrometer in terms of structure and principles. Determinations were carried out on tree height of 32 Celtis tetrandra in the arboretum of Southwest Forestry University, Yunnan province, by the dendrometer, portable laser range finder and compass. Taking tape measure value as true value, comparisons on measured values by different devices demonstrated that the accuracy and mean square error of wearable tree-height dendrometer was the best.
