Claim One:
1. A method for automatically correcting camera pose data, the method comprising: obtaining, by one or more computing devices, a plurality of images of a geographic area and image pose data that indicates, for each of the plurality of images, respective approximate location and orientation of a camera used to generate the image; identifying, by the one or more computing devices, a reference object captured in at least one of the plurality of images by selecting the reference object based on (i) mobility or (ii) flexibility of the reference object; determining, by the one or more computing devices, an estimated location of the reference object; selecting, by the one or more computing devices, from the plurality of images, a plurality of groups of images in which the reference object is captured; and generating, by the one or more computing devices, corrected image pose data based at least in part on the plurality of groups of images and the estimated location of the reference object by aligning, by the one or more computing devices, one or more common points on a surface of the reference object within the plurality of groups of images in which the reference object is captured by aligning images from each of the plurality of groups captured from different positions from each other.
