Abstract
According to one example embodiment, a computing device can include a camera, one or more processors, and one or more computer-readable media that store instructions that, when executed by the one or more processors, cause the computing device to perform operations. The operations can include defining a camera model of the camera based at least in part on location data associated respectively with an object in an image of a night sky and a cataloged star that corresponds to the object. The operations can further include performing an iterative process to iteratively update the camera model. For at least one iteration of the iterative process the operations can further include updating the camera model based at least in part on additional location data associated respectively with an additional object in an additional image of the night sky and an additional cataloged star that corresponds to the additional object.
