摘　　要：针对古栈道遗址的精密测绘与三维建模的需求,该文采用无人机倾斜航空摄影测量的方法获取山崖航摄影像并生成点云,采用地面三维激光扫描的方法获取栈孔数据并生成点云,将两种点云数据利用最近点迭代算法相融合,获得融合点云并生成三角网模型,附上纹理贴图,便得到了遗址现状的三维数字模型,并利用该模型完成了虚拟复原。本次古栈道精密测绘及复原在国内尚属首次,为相关研究提供了新方法。For the demand of precision mapping and 3D modeling of ancient gallery road site,the unmanned aerial vehicle（UAV）oblique aerial photogrammetry was used to obtain cliff air photo and generate point cloud,and the terrestrial laser scanning（TLS）technology was adopted to obtain holes data and generate point cloud,then two kinds of point cloud data were combined by using iterative closest point algorithm to obtain fusion point cloud and generate triangular network model;3Ddigital model for current site was obtained by accompanying with texture mapping,and virtual recovery was completed by using the model.It is the first time for precision mapping and recovery of ancient gallery road site at home,which provides new method for correlational research.
