Abstract: Methods, systems, and computer program products are provided for determining camera parameters and three dimensional locations of features from a plurality of images of a geographic area. These include, determining a correlation between a pose of a first camera and a pose of a second camera, generating one or more constraints incorporating the correlation, and determining at least one of camera parameters and three dimensional locations of features using a plurality of constraints including the generated one or more constraints. The first camera and the second camera have substantially rigid positions and poses relative to each other. A strength of the correlation is based at least upon a time interval between respective image captures by the first camera and the second camera.

Abstract: Methods, systems, and computer program products are provided for determining camera parameters and three dimensional locations of features from a plurality of images of a geographic area. These include, detecting features in the plurality of images where each of the images cover at least a portion of the geographic area, comparing the detected features between respective ones of the images to determine a plurality of matched features, selecting a subset of the plurality of matched features, and determining the camera parameters and the three dimensional positions of one or more of the detected features using the selected subset. The respective matched features are selected depending on a quantity of other matched features in proximity to the respective matched features.

Abstract: The subject matter of this specification can be implemented in, among other things, a method for generating a set of planar mediums (e.g., pages) for three dimensional model construction. The method includes a step for receiving three dimensional object data from a client computing device. The method includes a step for categorizing the three dimensional object data into a plurality of faces, wherein each face represents a two dimensional polygon of a part of the three dimensional object, and wherein connectivity information for each face of the plurality of faces to other faces of the plurality of faces is maintained. The method includes a step for selecting two faces from the plurality of faces for digital joining. The method includes a step for digitally joining the selected two faces to fit on a planar medium. The method includes a step for generating one or more digital images which contain the digitally joined faces from the plurality of faces.
