摘　　要：针对传统大比例尺地形图测绘方法存在成图周期长、外业工作量大、效率低等缺点,本文提出一种基于倾斜摄影测量技术测绘大比例尺地形图的方法。首先利用Context Capture软件对倾斜影像进行空中三角测量,获得试验区正射影像和精细化实景三维模型成果,然后基于EPS平台二三维联动一体化技术进行地形图测绘,最后对地形图成果进行精度评定。试验结果表明,该方法能够满足1∶500地形图精度要求,适合大比例尺地形图的快速更新。The traditional large-scale topographic mapping method has the disadvantages of long mapping cycle,large filed workload and low efficiency.This paper proposes a method of surveying and mapping large-scale topographic map based on oblique photogrammetry.First,use the Context Capture software to perform aerial triangulation on oblique images to obtain the orthophoto and the real-scene 3D model of the test area.The two-three-dimensional linkage integrated technology based on EPS platform was use to map topographic map,and finally the accuracy of the topographic map was evaluated.The test results show that the method can meet the 1∶500 topographic map accuracy requirement and is suitable for the rapid update of large-scale topographic maps.
