摘　　要：针对常规地基干涉合成孔径雷达(GB-InSAR)监测存在依赖地表控制坐标的问题,通过露天可控模拟试验,尝试利用三维激光扫描技术在扫描建模的同时,获取雷达的位置坐标并将其统一到模型的局部坐标系中,直接进行几何映射三维匹配,减少了测量雷达真实坐标及仪器坐标与真实坐标相互转换的步骤。通过在贵州晴隆滑坡抢险行动中的实际应用,能够直观判断危险源位置,分析滑动路径,效果良好。结果表明:将三维激光扫描建模技术与几何映射匹配方法相结合,能够在滑坡现场完成快速建模和匹配,实现雷达变形数据的三维可视化。提出的方法可为快速定位滑坡危险源、分析滑动路径及受灾范围提供便利。Traditional GB InSAR monitoring relies on surface control coordinates,which can be limiting.To quickly generate a digital elevation model(DEM)at the landslide disaster site,match it with radar deformation images,and achieve three-dimensional visualization of monitoring data,through controlled outdoor simulation experiments,three-dimensional laser scanning technology was used to capture the radar position coordinates during scanning.The position coordinates were integrated into the model’s local coordinate system for direct geometric mapping and three-dimensional matching,which reduces the steps of converting the real coordinates of the measuring radar and instrument coordinates to the real coordinates.Applying this method to a landslide rescue operation in Qinglong,Guizhou can intuitively determine the location of the hazard source,analyze the sliding path,and achieve effective results.The findings indicate that combining 3D laser scanning with geometric mapping matching method enhances rapid modeling and matching at landslide sites,and achieves 3D visualization of radar deformation data.This study facilitates quick location of landslide hazards and analysis of sliding paths and affected areas.
