With the development of network teaching , virtual technology teaching for experimental teaching ,which can strengthen the laboratory construction and reforming experiment teaching methods ,is an important development direction .This paper introduces the virtual modeling and development software , w hich elaborates the specific process of the virtual aerial photography measurement system design and implementation and builds the virtual aerial photography measurement system by using VRML software primarily with three‐dimensional modeling software SkecthUP and 3Ds Max .The system mainly includes virtual landform sand table(virtual campus model and virtual grid terrain) ,virtual digital photogrammetric workstation model , virtual unmanned aerial vehicle and control orbit dynamic model , and the virtual laboratory . It realizes virtual aerial photography measurement system’s main function :digital photogrammetric workstation dynamic demonstration operation ,unmanned aircraft aerial survey operation demonstration and visit to laboratory and demonstration and so on .T he result of the study has effectively improved the photogrammetry experiment teaching quality because it has no physical laboratory space and time limit w hich is helpful for students to develop independent learning . It has a certain reference significance for the virtual experiment system for research and development .
