基于激光雷达对北京中心城区历史建筑保护研究——以永定门城楼为例

Research on the Protection of Historical Buildings in the Central Area of Beijing Based on Lidar——Taking Yongdingmen Tower as an Example

按照世界文化遗产标准,进一步加大对北京中心城区历史建筑的保护力度,实施北京中心城区古建筑群修缮工程,把文物修缮同改善环境质量和提升居民生活水平有机结合起来,重要遗产点内的不合理使用问题将在中轴线申遗过程中尽可能得到协调解决。处理好点、线、面的关系,做到遗产点、历史建筑保护地带、街区背景相一致。现存城楼是根据传统制式于2004年复建而成,可通过扫描技术进行保护研究从而形成利用数字化技术对北京中心城区历史建筑保护的方法论。

According to the world cultural heritage standards,the research should further strengthen the protection of historical buildings in the central area of Beijing,implement the renovation project of ancient buildings in the central area of Beijing,combine the restoration of cultural relics with the improvement of environmental quality and the improvement of people’s living standards organically,and the problem of unreasonable use in important heritage sites will be solved as far as possible in the process of applying for the world heritage of the central axis.The relationship among points,lines and surfaces should be handled well,so as to make heritage sites,historical buildings protection zones and block backgrounds consistent.The existing city gate tower was rebuilt in 2004 according to the traditional system,and it can be protected by scanning technology,so as to form the methodology of using digital technology to protect historical buildings in the central area of Beijing.
