Three-dimensional terrain reconstruction of large-scale simulation based on multi-source remote sensing data
This paper focuses on the application of city-level 3D terrain reconstruction for virtual simulation applications,and studies the rapid reconstruction method of large-scale basic 3D model with 10-meter resolution based on remote sensing data.The reconstruction method uses satellite digital elevation model to complete the white model reconstruction of three-dimensional model,introduces multi-spectral remote sensing data to complete the model mapping generation,and optimizes the model details by using various remote sensing parameters.The results show that the 3D terrain model can render and display 8000 km2 urban 3D terrain in virtual simulation software,and can meet the requirements of terrain details and authenticity in virtual simulation applications.
