摘　　要：利用三维激光扫描系统,获得林木伐根的点云数据,使用Trimble Realworks软件提供的丰富的点云数据处理功能测量伐根直径,计算出林木的材积。将计算结果与传统方法测得的伐根直径计算出的材积结果进行比较。结果表明,三维激光扫描仪测量林木伐根直径得到的材积,符合材积测定的精度要求,测量效率远远高于传统测量的方法,并可以固定现场和复原现场,完成室内测量,为快速、高效地测量涉案林木材积提供了技术支持。Use 3D laser scanning to obtain the point cloud data of the tree stump, and use the rich point cloud data processing function provided by Trimble Realworks software to measure the stump diameter and calculate the volume of the tree. Comparing the calculated results with those measured by traditional methods, it is shown that the volume obtained by measuring the diameter of the tree stump by the three-dimensional laser scanner meets the accuracy requirements of volume measurement, and the measurement efficiency is much nigher than that of traditional measurement methods, and the site can be fixed and restored. The indoor measurement was completed, which provided technical support for quickly and efficiently measuring the timber volume of the forest involved.
