Digital Line Graphic generation method based on aerial photography image of unmanned aerial vehicle

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.
