Surveying and mapping system and method for outdoor geographic surveying and mapping

The invention belongs to the technical field of geographic surveying and mapping, and particularly relates to a surveying and mapping system for outdoor geographic surveying and mapping. The system comprises a surveying and mapping unmanned aerial vehicle, a coordinate navigation module, a video information acquisition module, a computer, a wireless signal transmission module, a self-stabilizationadjustment module, a power module, a positioning module and a surveying and mapping data analysis module, the computer inputs a surveying and mapping instruction into a control module of the surveying and mapping unmanned aerial vehicle, geographic positions are surveyed and mapped through the operation of all modules in the surveying and mapping unmanned aerial vehicle, and the geographic positions are transmitted to a computer background through wireless signals. The flight height and longitude and latitude information are used as the basis of automatic route scanning and camera shooting intervals, compared with tr
