中文摘要：

树木高度的测量工作是林业生产、科研、教学和森林调查的一项重要工作,是评价林木生长状况的重要依据。该文在对树木高度测量方面摒弃了繁重的测量设备,将近景摄影测量原理与当下时兴的安卓智能手机应用程序（Application）相结合,提出了一种新的测量树高的方式。测量者输入必要的参数并进行简单的操作,应用程序调用手机内部的方向传感器获取其倾斜角度数据,再结合所输入的参数先得到精确的树木离测量者的距离,然后通过一定的数学模型演算出树木的高度。此方法轻便、快捷,且精度较能满足需求,适合在野外没有专业测量工具时对树高进行较为准确的估测。

英文摘要：

Measuring the height of trees is an important work of forestry production,research,teaching and forest surveys,which is a basis to evaluate the growth of trees. Instead of using heavy equipment,the principal of Close-Range Photogrammetry with the fashionable Android smartphone applications should be combined,and a new way was proposed to get tree height measured. After inputting necessary parameters and performing the simple operation,a tilt angle data by calling the phone＇s internal orientation sensor could be formed,and then the accurate distance from the surveyor to the tree could be got. Next,the tree height through a certain mathematical model could be calculated. As omitting cumbersome steps,this method meets the accuracy requirements roughly.
