摘要
古建筑是一种文化精神的载体,随着岁月的流逝,在外在环境及自然灾害的影响下,古建筑的保护与修缮迫在眉睫.目前,对古建筑的测量,国内外常用的方法主要有全站仪离散点测量法、近景摄影测量法、全站仪与摄影测量集成法、三维激光扫描法等.本文以同乐傈僳族民居建筑群1号至10号民居文物保护修缮项目为例,基于通过三维激光扫描技术获取的点云数据,对古建筑的外立面、内部结构、顶面以及院落进行了扫描.基于法如场景(FARO SCENE)软件进行点云数据处理,利用计算机辅助设计(CAD)软件提取建筑特征信息,绘制民居建筑及院落平面图、立面图、剖面图.使用传统测量手段对本次扫描成果的测量精度和准确性进行了检查评价,为后续民居建筑群保护和修缮提供精确数据.
Abstract
Ancient architecture is a carrier of cultural spirit.With the passage of time,the protection and restoration of ancient architecture are imminent under the influence of external environments and natural disasters.At present,there are many methods to measure ancient architecture in China and abroad,such as discrete point measurement of total station,close-range photogrammetry,integration of total station and photogrammetry,and three-dimensional(3D)laser scanning.This paper took residential buildings 1-10 of the Lisu nationality in Tongle as an example.Based on the point cloud data obtained by 3D laser scanning technology,the exterior facade,interior structure,roof,and courtyard of the ancient architecture were scanned.Based on FARO SCENE software,the point cloud data was processed,and the feature information of the architecture was extracted by computer-aided design(CAD)software.The plan,elevation,and section of the residential buildings and courtyards were drawn.The accuracy of the scanning results was evaluated by traditional measuring methods,providing accurate data for the subsequent protection and restoration of residential buildings.
