BIM技术、三维扫描技术、GIS技术在古建筑修复保护中的运用研究

Research on the Application of BIM Technology,3D Scanning Technology and GIS Technology in the Restoration and Protection of Ancient Buildings

中国古建筑是中华文化艺术的瑰宝,古建筑保护修缮工作受到社会越来越多的重视。在当今社会各领域数字化、信息化的整体迅速发展的时代,古建筑数字化保护已经逐步走入大众的视野,古建筑保护修缮所运用的技术也随之不断更新。本文以丽江古城的典型古建筑代表木府作为研究对象,研究三维激光扫描技术、BIM技术、倾斜摄影技术在古建筑修复中的运用,并采集并处理其中的点云数据,发现木府古建筑存在的损坏状况,根据得到的点云数据和BIM参考模型,找出适合修复古建筑的方法,对古建筑进行预防性修复。并且对古建筑进行安全评估,找到古建筑档案保护系统建立的理论方法。

Chinese ancient architecture is a treasure of Chinese culture and art.The protection and repair of ancient architecture has received more and more attention from the society.In today’s era of the rapid development of digitalization and informationization in all areas of society,the digital protection of ancient buildings has gradually entered the public’s vision,and the technology used for the protection and repair of ancient buildings has been continuously updated.This article takes the typical ancient building of the ancient city of Lijiang as the research object,and studies the application of 3 D laser scanning technology,BIM technology,and oblique photography technology in the restoration of ancient buildings.Existing damage conditions,based on the obtained point cloud data and BIM reference model,find a method suitable for repairing ancient buildings,and preventively repair ancient buildings.In addition,the safety assessment of ancient buildings is carried out to find the theoretical method for the establishment of the ancient building archives protection system.
