摘要
建筑物立面图在城市空间信息管理、城市规划建设中发挥着重要作用,传统的立面图测绘主要以全站仪、经纬仪为主,虽然测量点位精度较高,但是内外业工作量都较大。无人机近景摄影具有数据采集简单、建模成本低、建模速度快等优势,是获取建筑物三维数字化信息的理想方式。本文以某工程实践为例,将近景摄影测量技术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具有较高的参考价值。
Building elevation view plays an important role in urban spatial information management,urban planning and construction.The traditional facade measurement is mainly based on total station and theodolite.Although the measurement points accuracy is high,but the workload of both indoor and field is large.UAV close-range photography has the advantages of simple data acquisition,low modeling cost and fast modeling speed,which is an ideal way to acquire 3D digital information of buildings.In this paper,taking an engineering practice as an example,the close-range photogrammetry technology is applied to the building facade measurement,and a set of practical facade measurement technology flow is developed.The research results have strong reference value for the effective collection of building facade data,the later management and the establishment of a perfect building archives.
