摘要
北斗卫星导航系统为无人机测量技术在工程监测领域提供了高精度定位支撑。该技术融合北斗实时动态定位技术(RTK)定位、无人机遥感和数据处理算法,实现厘米级测量精度和实时监测能力。通过构建三维模型和多时相对比分析,能够精确监测工程变形、沉降和进度等关键指标。某大型基础设施项目应用表明,北斗支持下的无人机测量系统监测精度达到±2 cm,数据获取效率提升80%以上,为工程安全管理和质量控制提供了可靠的技术保障,推动了工程监测向智能化、精准化方向发展。
The BeiDou Navigation Satellite System(BDS)provides high-precision positioning for UAV-based engineering monitoring.This study presents an integrated approach that synergizes BDS Real-Time Kinematic(RTK)positioning,UAV remote sensing,and data processing algorithms to achieve centimeter-level accuracy and real-time capability.Through 3D modeling and multitemporal analysis,the method enables precise tracking of critical parameters,including structural deformation,settlement,and progress.Applied to a large-scale infrastructure project,the system demonstrated a monitoring accuracy of±2 cm and improved data acquisition efficiency by over 80%.The results confirm that this integrated technology provides reliable support for engineering safety and quality control,promoting a shift towards intelligent and precise monitoring practices.
