1. A method for determining one or more camera calibration parameters, comprising: determining, by one or more computing devices, a set of common features between a plurality of photographic images taken by a camera, the set of common features including at least a portion of a same object captured in each of the photographic images; receiving, by the one or more computing devices, acceleration data provided by an accelerometer coupled to the camera, wherein the acceleration data is received for each of the captured photographic images; and calculating, by the one or more computing devices, values for each of the one or more calibration parameters of the camera, based on at least the determined set of common features and the received acceleration data for each of the captured photographic images; wherein the determining includes determining the set of common features between photographic images of varying pitch or roll angle; and wherein the calculating includes calculating a value for at least one of a focal length, a lens distortion, and an optical center associated with the camera.
