Abstract: Real-time registration of a camera array in an image capture device may be implemented in the field by adjusting a selected subset of independent parameters in a mapping function, termed registration coefficients, which have been determined to have the largest contribution to registration errors so that the array can be maintained in its initial factory-optimized calibrated state. By having to adjust only a relatively small subset of registration coefficients from within a larger set of coefficients (which are typically determined using a specialized calibration target in a factory setting), far fewer matching patterns need to be identified in respective images captured by cameras in the array in order to correct for registration errors. Such simplified pattern matching may be performed using images that are captured during normal camera array usage so that registration may be performed in real-time in the field without the need for specialized calibration targets.

The second landmark is moved based on how the contour point was manually moved so that the first and second images are more finely coregistered after the second landmark is moved. Each state of corrected contour points and landmarks is saved.

Oblique images offer a rich set of views of a target location and provide a smooth transition to or from other images such as nadir photographs taken by satellites or street level photographs taken by ground level users. Using unstitched oblique images avoids artifacts that may be introduced when stitching together one or more images. This allows an application to display images to a user and create the illusion of three dimensional motion.
