Rural house and land integrated investigation database building method based on hybrid network

The invention discloses a rural house and land integrated investigation database building method based on a hybrid network. An oblique photogrammetry model is re constructed through quadtree operation, the data volume of sparse and broken tile files is reduced, the number of tiles is greatly reduced, and the problems of low loading efficiency, large scene rendering consumption and the like when a user processes a large batch of oblique photogrammetry data are solved, a mobile terminal can rapidly load an oblique photogrammetry model, then two-dimensional vector data of a staple map and a house plane graph and the oblique photogrammetry model are subjected to segmentation and attribute hooking, and mobile terminal technologies such as visual mobile investigation and GPS positioning are realized to provide support for field investigation; and the problems of low field data loading speed and multi-person collaborative operation are balanced in an off-line and on-line combined mode, so that indoor and outdoor wor
