Room and land integrated measurement method based on clustered fine three-dimensional model

The invention provides a clustered fine three-dimensional model-based house and land integrated measurement method, which is characterized by comprising the following steps of: arranging a plurality of image control points in an area to be measured, and collecting the plurality of image control points; planning the route of the unmanned aerial vehicle carrying the camera; controlling the unmanned aerial vehicle to carry out field flight according to the planned route of the unmanned aerial vehicle; photographing a picture of the to-be-detected area; performing clustering processing on the photos of the to-be-detected area; reconstructing a refined three-dimensional model and producing an orthoimage map; and drawing a digital line drawing of the to-be-measured area according to the refined three-dimensional model and the orthophoto map. According to the house and land integrated measurement method based on the clustered fine three-dimensional model, the personnel and cost investment can be reduced, the field c
