Abstract: A camera pose may be determined automatically and is used to map texture onto a 3D model based on an aerial image. In one embodiment, an aerial image of an area is first determined. A 3D model of the area is also determined, but does not have texture mapped on it. To map texture from the aerial image onto the 3D model, a camera pose is determined automatically. Features of the aerial image and 3D model may be analyzed to find corresponding features in the aerial image and the 3D model. In one example, a coarse camera pose estimation is determined that is then refined into a fine camera pose estimation. The fine camera pose estimation may be determined based on the analysis of the features. When the fine camera pose is determined, it is used to map texture onto the 3D model based on the aerial image.
