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。
Based on the Android system, explore the use of mobile phone camera this non-professional equipment to measure the tree height and DBH method. The trigonometric method and image analysis method were used to study the tree height and diameter at breast height. The tree height and diameter at breast height were measured, and the tree-based measurement system was developed. The system of tree measurement based on Android was developed. The equipment presetting, target distance calculation, And DBH calculation functions. The experimental verification results show that the relative errors of the measured results are within 5%, which can be used to measure the height and diameter of standing tree.
