基于手持扫描仪的建筑立面测量方法研究

Research on Measuring Method of Building Facade Based on Handheld Scanner

传统建筑平面与立面测量存在效率低、外业工作量大等不足,而手持实景扫描仪具有实景复制能力强、效率高等优势。基于此,本文以一栋六层建筑为研究对象,从数据采集、数据处理、成果绘制等过程详细介绍了一套基于手持实景扫描仪的建筑平面、立面测量方法,并将测量成果与手持激光测距仪测量建筑边长进行精度对比分析,同时与其他测量方法进行效率对比分析。研究结果表明:手持实景扫描仪可以快速获取建筑室内、室外点云数据,可以高效快速进行建筑立面、平面测量,精度误差为0.022 m,满足项目精度要求,且与传统方法相比,工作效率也大幅度提升。

Traditional building plane and facade measurement has the disadvantages of low efficiency and large field workload. Handheld real scene scanner has the advantages of real scene replication ability and high efficiency.Based on this, this paper takes a six-story building as the research object,from data acquisition, data processing and results drawing process, introduces in detail a set of architectural plane based on handheld imaging scanner, measurement method, and the measurement results and the hand-held laser range finder to measure architecture side length accuracy comparison analysis, efficiency compared with other methods of measuring analysis at the same time. The results show that handheld real scene scanner can quickly obtain the indoor and outdoor point cloud data of buildings, and can efficiently and quickly measure the building elevation and plane. The accuracy error is 0.022 m, which meets the requirements of project accuracy. At the same time, compared with the traditional method, the work efficiency is also greatly improved.
