三维激光扫描技术在建筑物立面图测绘中的应用研究

Research on the Application of 3D Laser Scanning Technology in Building Elevation Map Surveying and Mapping

城市化发展规划、旧城改造过程中,老旧建筑物立面信息数据已成为建筑物修缮改造的重要基础和依据,传统粗放式测量技术手段存在工作量大、工作效率低、对外界环境要求高以及细部特征采集不全等诸多局限性。本文以某工程实践为例,将三维激光扫描应用到建筑物立面测量中,制定了一套切实可行的立面测量技术流程,研究结果对建筑物立面数据的有效采集、后期管理以及建立完善的建筑物档案资料具有较强的参考价值。

In the process of urbanization development planning and old city reconstruction, the facade information data of old buildings has become an important basis and basis for building repair and reconstruction. The traditional extensive measurement technology has many limitations, such as heavy workload, low efficiency, high requirements on the external environment and incomplete collection of detailed features. Taking an engineering practice as an example, this paper applies 3D laser scanning to building facade measurement, and develops a set of practical facade measurement technology flow. The research results have strong reference value for effective collection of building facade data, later management and the establishment of sound building archives.
