Abstract
Embodiments facilitate the calibration of cameras in a live action scene using drones. In some embodiments, a method configures a plurality of reference cameras to observe at least one portion of the live action scene. The method further configures one or more moving cameras having unconstrained motion to observe one or more moving objects in the live action scene and to observe at least three known reference points associated with the plurality of reference cameras. The method further receives reference point data in association with the one or more moving cameras, where the reference point data is based on the at least three known reference points. The method further computes a location and an orientation of each moving camera of the one or more moving cameras based on one or more of the reference point data and one or more locations of one or more reference cameras of the plurality of reference cameras.
