1. A computer-implemented method for creating a three-dimensional model, comprising:

  • receiving, by one or more computing devices, an automatically generated three-dimensional model geocoded within a first field of view of a first camera that tools a first two-dimensional photographic image and geocoded within a second field of view of a second camera that took a second two-dimensional photographic image, wherein a first perspective of the first camera that took the first two-dimensional photographic image is represented by a first set of camera parameters for the first two-dimensional photographic image and a second perspective of the second camera that took the second two-dimensional photographic image is represented by a second set of camera parameters for the second two-dimensional photographic image, wherein the first set of camera parameters includes at least a first focal length associated with the first two-dimensional photographic image and a first capture location at which the first two-dimensional photographic image was captured, wherein the second set of camera parameters includes at least a second focal length associated with the second two-dimensional photographic image and a second capture location at which the second two-dimensional photographic image was captured, wherein the first capture location and the second capture location comprise locations in three-dimensional space, and wherein each of the one or more computing devices comprises one or more processors;

    receiving, by the one or more computing devices, a first user input constraint indicating that a feature of the automatically generated three-dimensional model corresponds to a first position on the first two-dimensional photographic image;

    receiving, by the one or more computing devices, a second user input constraint indicating that the feature of the automatically generated three-dimensional model corresponds to a second position on the second two-dimensional photographic image;

    determining, by the one or more computing devices, a first point in three-dimensional space by extending a first ray from the first capture location through the first position on the first two-dimensional photographic image as indicated by the first user input constraint, the first ray having the first focal length;

    determining, by the one or more computing devices, a second point in three-dimensional space by extending a second ray from the second capture location through the second position on the second two-dimensional photographic image as indicated by the second user input constraint, the second ray having the second focal length; and

    when the first point in three-dimensional space and the second point in three-dimensional space are located at a same position, altering the automatically generated three-dimensional model such that the feature is located at the same position in three-dimensional space.
