This paper studies the method of quickly vectoring rural buildings by taking P village in Guangdong Province as an example.It firstly establishes a digital model by using UAV aerial survey technology and real-time 3D modeling technology.Then,it quickly surveys the scattered and disor-dered rural buildings,and implements the vectorization process of automatic boundary extraction,opti-mization,and recognition by performing boundary vectorization iteration through involking real-time 3D model and BP neural network model in Matlab.It is concluded from error analyzing that the accuracy from this method is relatively good,it has some research significance and application prospects.
