Reconstruction of 3D Maps for 2D Satellite Images

In this paper, we will propose a new approach of building 3D maps from 2D satellite map images. Firstly, we get a 2D satellite map image from Google Earth. Then we use OpenCV to extract the elements' boundaries automatically on the 2D map image. Next, we correct the automatic extraction result and set the information of the elements on the map manually. After extraction and setting is finished, we will get the data (elements' boundaries, types, locations, textures, heights) of the elements on the 2D map. With these data, we can establish the virtual 3D digital map of the scenes. At the same time, we will add textures to the 3D models in the 3D scenes. To be more user-friendly, the system provides data gloves based roaming and can synchronize the 3D scenes with Android clients.
