| Abstract: | 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. |
