利用智能手机摄像头和虚拟角规原理,在小米3和魅族MX2两款手机上实现了虚拟角规,并将其集成在一款Android野外测树及数据记录处理应用程序中,利用手机触摸屏实现了在调查数据散点图上画随手曲线的功能,为小班调查野外作业提供了便捷的工具,同时,还实现了与该款软件相匹配的一款桌面应用程序,方便后续内业数据的汇总处理。

According to the principle of virtual angle gauge,this article implements the virtual angle gauge on MIUI 3 and Meizu MX2 mobile phones.And it has been integrated in an android-based sub-compartment tree measurement data recording and processing APP program.This APP provides a convenient tool for sub-compartment tree measurement work,and uses touch screen to achieve free hand curve plotting on the measurement data scatter diagram .In order to summarize and process follow-up forestry data conveniently,this article also develops a Windows desktop application which could collaborate with the APP.
