Planning Verification Measurement Method and Accuracy Verification Based on Three-Dimensional Laser Scanning Technology

摘要: 为克服传统建筑物竣工测量方法存在的效率低、环境适应性差及细节获取不足等问题，本研究系统探索了新型徕卡RTC360三维激光扫描仪在该领域的应用。研究选取约40万平方米的建成住宅小区作为实验区，建立了完整的技术流程：利用RTC360进行外业快速数据采集；采用徕卡Cyclone软件进行点云拼接、去噪与绝对定向处理；基于处理后的高精度点云，利用清华三维EPS软件绘制建筑物立面图与竣工地形图。精度检验结果表明，所获立面图中误差为0.011 m，地形图平面中误差为0.026 m，高程中误差为0.013 m，均满足《城市测量规范》要求。效率对比分析显示，RTC360方案总工期仅需5天，远低于传统全站仪法(9.75天)和常规扫描仪法(7.5天)，其单站扫描速度快(最快26秒)、非接触测量方式有效解决了高空、异形结构测量难题，并确保了数据完整性与可视化。尽管存在建筑密集区需设站较多(本实验74站)及顶部点云易缺失等局限，研究证实RTC360为建筑物竣工测量提供了一种高精度、高效率、高完整性的创新解决方案，具有良好的应用前景。

Abstract: To overcome the issues of low efficiency, poor environmental adaptability, and insufficient detail acquisition in traditional building completion survey methods, this study systematically explores the application of the new Leica RTC360 3D laser scanner in this field. A built residential area covering approximately 400,000 square meters is selected as the experimental area, and a complete technical process is established: rapid data acquisition in the field using the RTC360; point cloud stitching, denoising, and absolute orientation processing using Leica Cyclone software; based on the processed high-precision point cloud, building elevation maps and completion topographic maps are drawn using Tsinghua 3D EPS software. The accuracy inspection results show that the error in the obtained elevation map is 0.011 m, the error in the topographic map plane is 0.026 m, and the error in elevation is 0.013 m, all of which meet the requirements of the “Urban Surveying Specifications”. Efficiency comparison analysis shows that the total construction period of the RTC360 scheme is only 5 days, which is much lower than that of the traditional total station method (9.75 days) and conventional scanner method (7.5 days). Its single-station scanning speed is fast (up to 26 seconds), and its non-contact measurement method effectively solves the measurement challenges of high-altitude and irregular structures, ensuring data integrity and visualization. Despite limitations such as the need for multiple stations in densely populated areas (74 stations in this experiment) and the potential loss of top point clouds, the study confirms that the RTC360 provides an innovative solution for building completion surveying that is high in precision, efficiency, and integrity, with good application prospects.
