【摘要】:針對(duì)古棧道遺址的精密測(cè)繪與三維建模的需求,該文采用無(wú)人機(jī)傾斜航空攝影測(cè)量的方法獲取山崖航攝影像并生成點(diǎn)云,采用地面三維激光掃描的方法獲取?讛(shù)據(jù)并生成點(diǎn)云,將兩種點(diǎn)云數(shù)據(jù)利用最近點(diǎn)迭代算法相融合,獲得融合點(diǎn)云并生成三角網(wǎng)模型,附上紋理貼圖,便得到了遺址現(xiàn)狀的三維數(shù)字模型,并利用該模型完成了虛擬復(fù)原。本次古棧道精密測(cè)繪及復(fù)原在國(guó)內(nèi)尚屬首次,為相關(guān)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引言蜀道是穿越秦嶺巴山連接川陜地區(qū)的一系列古代道路的總稱(chēng),其歷史極為悠久,開(kāi)辟時(shí)間可上溯至先秦時(shí)期,到清代仍發(fā)揮著重大作用。蜀道沿線(xiàn)曾開(kāi)鑿大量棧道,它是古人為方便在山谷中通行并避開(kāi)谷中溪流,依傍山崖而修建的構(gòu)筑物。修筑棧道時(shí)先在崖壁上開(kāi)鑿棧孔,再于孔內(nèi)安置木,
