Unmanned aerial vehicle detection method and system based on surveying and mapping, storage medium and intelligent terminal

The invention relates to an unmanned aerial vehicle detection method and system based on surveying and mapping, a storage medium and an intelligent terminal, and relates to the field of surveying and mapping. The method comprises the steps that: an unmanned aerial vehicle carries out collection, and inputs current image detection information into an overall database; after acquisition of the overall database is completed, a preliminary model is built; the unmanned aerial vehicle performs further acquisition and updates the preliminary model into a three-dimensional model in real time, and outputs current structural feature information from current image detection information in real time; whether the current structural feature information is consistent with features in a feature database or not is judged; if not, the current structural feature information is converted into three-dimensional features, a three-dimensional model is built, and the current structural feature information is updated to a feature dat
