Abstract:
1. An image capture system comprising: a first image capture subsystem comprising a first imaging device configured to capture, at a first instance in time, at least one overview image of an overview area, the at least one overview image having a first resolution; and a second image capture subsystem comprising a second imaging device configured to capture, substantially concurrent with the first instance in time, at least one detail image of at least a portion of the overview area, the at least one detail image having a second resolution higher than the first resolution, the first and second image capture subsystems being configured such that a plurality of overview images overlap to result in an overview redundancy of overview image elements appearing in the plurality of overview images and a plurality of detail images overlap to result in a detail redundancy of detail image elements appearing in the plurality of detail images, wherein a percentage overlap among the plurality of overview images is greater than a percentage overlap among the plurality of detail images, wherein after capture of the plurality of overview images and the plurality of detail images, interior and exterior orientations of the detail images are determined based on a bundle adjustment process using the plurality of overview images and the plurality of detail images in order to determine 3-dimensional coordinates of detail image elements, wherein the overview redundancy is greater than 10 images and the detail redundancy is less than or equal to 10 images, wherein an area of at least one overlapping overview portion between a first and second overview image is greater than or equal to 50% of an area of one of the first and second overview images, and wherein an area of at least one overlapping detail portion of a first and second detail image is less than or equal to 20% of an area of one of the first and second detail images.
