Abstract
Implementations facilitate the calibration of cameras in a live action scene. In some implementations, a system includes a base, where the base is configured to removably couple to a camera in the live action scene. The system further includes a plurality of extensions coupled to the base, where the plurality of extensions extends outwardly away from the base. The system further includes a plurality of reference points identifiable by a sensor, where the reference points are coupled to ends of corresponding extensions of the plurality of extensions, and where the plurality of extensions positions the plurality of reference points in a three-dimensional arrangement. Distances between pairs of reference points are based on one or more aspects of the extensions, and the distances between the pairs of reference points are used to compute reference point data generated from a performance capture system.
