摘　　要：为提高林业勘察的自动化与精确化,采用三维激光扫描仪对单颗树木的三维重建技术进行研究。通过无标靶配准算法对单颗树木的点云数据进行获取与配准,由Kd树结构对所采集到的点云数据进行管理,并进行树木的骨架点提取、骨架连接、重采样、树干表面生成、纹理贴合。最后通过三维软件Leica Cyclone对单颗树木点的云数据进行去噪等处理,运用Matlab软件绘制相关图像。结果表明:单颗树木重建的效果较为逼近树木原型。In order to improve the automation and accuracy of forestry survey, the three-dimensional reconstruction technology of single tree was studied by using three-dimensional laser scanner. The point cloud data of a single tree is acquired and registered by non-target registration algorithm. The collected point cloud data are managed by Kd tree structure, and the tree skeleton points are extracted, connected, resampled, trunk surface generation and texture matching are carried out. Finally, the cloud data of a single tree point are denoised by the three-dimensional software Leica Cyclone, and the related images are drawn by the software of Matlab. The results show that the effect of single tree reconstruction is close to the tree prototype.
