Abstract
Embodiments relate to selecting textures for a user-supplied photographic image in image-based three-dimensional modeling. In a first embodiment, a computer-implemented method includes a method positioning a geographic structure using user-supplied photographic images of a geographic structure. In the method, a user-supplied photographic images inputted by a user are received. Embedded camera parameters that specify a position of the cameras when each user-supplied photographic image was taken and are embedded in each user-supplied photographic image are read. An estimated location of the geographic structure is automatically determined based on the embedded camera parameters in each user-supplied photographic image. Each user-supplied photographic image to be texture mapped to the three-dimensional model is enabled.
