UAV ground-based targeting system and method for enhancing geographic information

The present invention provides a UAV ground-based positioning system and method for enhancing certain geographic information, the system comprising a UAV system, data transmission module and a ground station control system; the UAV system through the data transmission module information interaction with the ground station and the control system; wherein said system comprises a UAV real acquisition module, GPS positioning module and the attitude acquisition module; ground station control system comprising: an electronic map database, the projector module, and a traverse block positioning module . Advantages: no use of complex image processing algorithms, just to the real image and the three-dimensional map matching by a simple fitting method, to obtain a position value of the target point, and therefore, can be a wide range of target scene on the ground precise positioning, and, due to the simple positioning algorithm employed, therefore, positioning is very fast, can meet the demand for real-time tracking of the target.
