随着城市化进程的加快,准确高效的城市测量变得尤为重要。针对传统测量方法在复杂环境中存在效率低、成本高的问题,手持SLAM技术凭借其灵活性和实时性,为城市测量提供了创新方案。本文基于手持SLAM技术的城市测量方案,研究手持SLAM技术在建筑改造测绘、大比例尺地形图测绘、树木点状物工程测量等实际工程的应用,并验证手持SLAM技术的可行性。结果表明,手持SLAM在建筑改造测绘中能高效构建精确三维模型;在大比例尺地形图测绘中能快速采集地形数据;在树木点状物工程测量中能有效识别和定位测量点。与传统方法相比,手持SLAM技术高效、灵活、成本低,在实际项目中精度、实时性和稳健性良好。本文研究不仅验证了手持SLAM的应用价值,而且为推广应用提供了理论和实践基础,未来有望应用于更多领域。

With the rapid acceleration of the urbanization process,accurate and efficient urban measurement has become particularly crucial.Given the challenges of low efficiency and high costs associated with traditional measurement methods in complex environments,handheld SLAM technology emerges as an innovative solution,offering flexibility and real-time performance.This paper explores the application of handheld SLAM technology in practical projects,including architectural renovation mapping,large-scale topographic mapping,and tree point feature engineering measurement,thereby verifying its feasibility.The results demonstrate that handheld SLAM technology can efficiently construct accurate 3D models for architectural renovation mapping,swiftly collect topographic data to enhance efficiency in large-scale topographic mapping,and effectively identify and locate measurement points in tree point feature engineering measurement.Compared to traditional methods,handheld SLAM technology proves to be efficient,flexible,and cost-effective,exhibiting good accuracy,real-time performance,and robustness in actual projects.This research not only confirms the application value of handheld SLAM but also provides a theoretical and practical foundation for its promotion and application.It is anticipated that this technology will be applied in even more fields in the future.
