空地一体化测绘技术在历史文化街区修缮中的应用

Application of space-ground integrated surveying and mapping technology in reconstruction of urban historic conservation areas

历史文化街区修缮过程中,需要尽可能保留原有的建筑风貌,对于街区现状测绘提出了较高要求。本文将无人机倾斜摄影技术与三维激光扫描技术相结合,获取历史文化街区高密度、高精度的点云数据,用于制作街区历史建筑改造的现状图纸成果。实践证明,该空地一体化测绘技术在作业效率与成果精度上都较传统方法有所提升,所得到的点云数据能够更好地体现街区中历史建筑的原有风貌,服务于修缮方案设计。

In the process of repairing urban historic conservation areas,it is necessary to retain the original architectural style as much as possible,which puts forward higher requirements for the current surveying and mapping of blocks.In this paper,the UAV tilt photography technology and three-dimensional laser scanning technology are combined to obtain the high-density and high-precision point cloud data of historical and cultural blocks,which are used to make the current drawings of the reconstruction of historical buildings in the blocks.It has proved by practice that the space-ground integrated surveying and mapping technology has improved the operation efficiency and achievement accuracy compared with the traditional methods.The obtained point cloud data can better reflect the original style of historical buildings in the block and serve the repair scheme design well.
