摘要
快速大比例成图是地区发生地质灾害应急的关键。近年来,低空摄影测量系统迅速发展,具有低成本、简易化、专用化、速度快等优势。本文以陕北神木县为研究区域,采用动力三角翼系统,通过像点布设、相机标定、空三加密等过程,最终获得研究区的数字表面模型DSM(Digital Slope Model)和数字地面模型DTM(Digital Terrain Model),实验结果满足了大比例尺图精度要求,可以为灾害地区快速提供信息。
In recent years,the low altitude photogrammetry system has developed rapidly. It has the advantages of low cost,simplicity,specialization and fast speed. In Northern Shaanxi Shenmu County mine as the research area,the power system through the delta wing,like arrangement,camera calibration,empty three encryption process,finally obtained DSM（ Digital Slope Model） and DTM（ Digital Terrain Model）,the experimental results meet the accuracy requirements of the large scale map,can for the disaster areas to provide information quickly.
