基于Android系统,探索利用手机摄像头这一非专业装备来测量立木树高和胸径的方法。采用三角函数法和图像分析法对立木的树高、胸径测量方法进行研究,构建树高、胸径测量模型,开发了基于Android的测树系统,实现了设备预设、目标距离计算、立木树高以及胸径计算等功能。经实验验证,使用所开发的测树系统对立木树高、胸径进行测量,测量结果的相对误差均在5%以内,可以应用于实际立木树高、胸径的测量。
Abstract
Based on the Android system, using the phone camera, this study explored the utilization of non-professional equipment to measure the tree height and tree diameter at breast hight(DBH). Using the trigonometric function method and image analysis method, the tree height and DBH were measured with the Android platform. This study also developed some functions, such as the equipment presetting, calculation of the target distance and calculation of the tree height and DBH. Through the experimental validation, it was found that the relative errors of the measurements were within 5%, indicating that the system can be applied to the practical tree measurements.
