In recent years, the accuracy of photogrammetry has reached the measurement level requirements based on the consumer unmanned aerial vehicle (UAV) equipped with professional cameras, and has been widely used in many industries. Taking the current integration survey of real estate as the research object, technical route of using consumer UAV equipped with professional camera to obtain oblique image has been explored in this paper, and real scene 3D model has been automatically generated. By using EPS professional software, nakedeye 3D mapping has been carried out, and the accuracy of the mapping results has been verified. It is showed that the altitude is less than 100m, the image resolution is better than 3cm, and the mapping accuracy can meet the requirements of integration survey of real estate specification with the scale of 1∶500.
