| Abstract: | This article combining with progress of production practice,introduced the digital elevation model(DEM) which based on the unmanned aerial vehicle low altitude image process method.When producing scale 1:1000 DOM,it used the set point law to study the resolution criterion scope,and obtained the appropriate DEM resolution of the low altitude images of UAV,and evaluated the DEM precision at last. |
