1. A system for image calibration, comprising: a processing device; and modules to be implemented by the processing device, the modules comprising: a feature module to: detect features on a set of images; describe features on the set of images; determine a match between features of the image sets; and a homography module to: determine a shift on the matched features based on camera positions; determine a first homography between the camera positions and the determined shift; reconstruct the detected features in three-dimensions; and determine a second homography based on a re-projection of the three-dimensional features back to a plurality of cameras.
