摘　　要：传统大比例尺1∶500地形图的成图方法一般是全野外测量法和传统航测法,其野外工作量大,作业艰苦,作业程序复杂,同时还有繁重的内业数据处理和绘图工作,成图周期长。本文基于倾斜摄影影像,生产富锦市1∶500地形图,可满足富锦市的大比例尺地形图需求,探索倾斜摄影技术在大比例尺地形图测绘方面的应用。项目利用街景工厂对倾斜影像进行空中三角测量,获得倾斜摄影三维模型成果,在三维模型中进行测绘,再通过外业修补测成1∶500比例尺地形图,并对地形图成果进行精度分析和对数据的处理过程中存在的问题进行总结。The mapping method of traditional large scale 1 ∶500 topographic map is generally the whole field measurement method and the traditional aerial survey method. The field work is heavy, the operation is arduous, the operation procedure is complex, and there is still a lot of data processing and drawing in the industry, and the mapping period is long. Based on tilting photography, the 1 ∶500 topographic map of Fujin is produced to meet the needs of large scale topographic map in Fujin, and the application of oblique photography in large-scale topographic mapping is explored. The project by Street factory aerial triangulation to tilt image, gain tilt photography 3D model results of Surveying and mapping in the three-dimensional model, and then through the field test to repair 1 ∶500 topographic map, and the accuracy of the data analysis and processing in the process of the existing problems are summarized on topographic map.
