Combined with site visualization, the method of 3D site modeling is studied, and the visualization information management and VR display of 3D model based on tilt photography data are realized. For objects such as scene objects and buildings, 3dsMax and tilt photography are used to model the model, and in the aspect of model visualization, Super Map and Mars software are used to study the visualization of the model. Through the above model data processing, the repeated work of site model modeling is reduced, the modeling efficiency is improved, and the difficulty of site 3D model transformation is reduced
