SYSTEM FOR AUTHORING 3D VIRTUAL ENVIRONMENT USING DIGITAL ELEVATION MODEL AND OPERATING METHOD THEREOF

摘要

The operation method of the three-dimensional virtual environment authoring system according to the present invention includes the steps of inputting a digital elevation model (DEM), a digital surface model (DSM), and an orthographic image, a three-dimensional model of a building It may include inputting , initializing the position of the 3D model with respect to the building, and matching and fitting the 3D model to the numerical elevation model.
