基于激光测距的树高和胸径测量方法与研究

摘要

为提高森林资源的调查效率以及准确掌握与树木相关的重要参数,对基于激光测距的测定树高和胸径的方法进行了介绍,并对脉冲激光测距原理、三角高程法的测量原理以及精度计算进行分析,通过实例分析进行验证.结果表明,与传统的树高和胸径的测量方法相比,激光测距不仅测量精度高,而且效率高,具有很高的应用价值.%Principles and operation of laser ranging was introduced,for improving efficiency of forest resources monitoring and accuracy of tree traits. Instance analysis of tree height and DBH was verified.The results showed that compared with traditional measurement methods, raser ranging had advantages of higher accuracy and much more effective for measurement.
