【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。
[Abstract]:Aiming at the demand of precision mapping and 3D modeling of ancient trestle ruins, this paper adopts the aerial photogrammetry method of UAV tilting to obtain aerial photographs of cliffs and generate point clouds. Ground 3D laser scanning method is used to obtain stack hole data and generate point cloud. The two point cloud data are fused by nearest point iterative algorithm to obtain fusion point cloud and generate triangular mesh model with texture map attached. The 3D digital model of the status quo of the site is obtained, and the virtual restoration is completed by using the model. The precision mapping and restoration of the ancient trestle road is the first time in China, which provides a new method for the related research.

【正文快照】: 0引言蜀道是穿越秦岭巴山连接川陕地区的一系列古代道路的总称,其历史极为悠久,开辟时间可上溯至先秦时期,到清代仍发挥着重大作用。蜀道沿线曾开凿大量栈道,它是古人为方便在山谷中通行并避开谷中溪流,依傍山崖而修建的构筑物。修筑栈道时先在崖壁上开凿栈孔,再于孔内安置木,
