摘要
数字线划图(DLG)是国家与城市建设中重要的基础数据源,传统测绘作业数据作为DLG生产的基础,存在产品误差较大,产品质量得不到保证的缺点.本文基于无人机航摄影像进行DLG产品制作研究,实施了一种快速生成DLG产品的方法,通过质量分析和结果检验,证明了该方法的可行性.
Digital Line Graphic(DLG)is an important basic data source in national and urban construction.Traditional surveying and mapping data is used as the basis for DLG production.There is a large product error and the product quality is not guaranteed.DLG production is based on the research of aerial photography image of unmanned aerial vehicle.A method of quickly generating a DLG product is implemented.The feasibility of the method is proved by quality analysis and results test.
