摘　　要：传统的地形图绘制工作存在耗时长、现势性低、效率低、成本高等问题亟待解决。三维模型基于EPS平台绘制大比例尺地形图,可有效地改善地形图绘制工作存在的困难,为地形图绘制工作提供新技术、新方法。本文以石家庄某测区的大比例尺地图制图项目为背景,研究了基于无人机倾斜摄影的大比例尺地图制图,研究结果表明,三维模型纹理清晰、结构较为完整,真实性强;模型空三解算后的控制点和检查点的平面、高程精度均可以满足1∶500比例尺的精度要求;基于EPS平台绘制的大比例尺地形图精度满足1∶500地形图成图精度要求,即利用三维模型基于EPS平台绘制大比例尺地形图是一种省时、成本低、效率高、精度有保障的新方法。The problems of long time,low current situation,low efficiency,high cost and so on in the drawing of unified topographic map need to be solved urgently.3D model drawing large scale topographic map is based on EPS platform can effectively improve the difficulties in topographic map drawing work,providing new technology and new method for topographic map drawing work.Based on the large-scale mapping project in a survey area of Shijiazhuang,this paper studies the large-scale mapping based on UAV tilt photography.The results show that the texture of 3Dl model is clear,the structure is relatively complete,and the authenticity is strong.The plane and elevation accuracy of the control points and inspection points after the spatial 3D solution of the model can meet the accuracy requirements of 1:500 scale.The precision of large-scale topographic map drawn based on EPS platform meets the requirements of mapping precision of 1:500 topographic map,that is,drawing large-scale topographic map based on EPS platform using 3D model is a new method with time-saving,low cost,high efficiency and guaranteed precision.
