CALIBRATING DEVICES BY SELECTING IMAGES HAVING A TARGET HAVING FIDUCIAL FEATURES

Devices and techniques are described for automatically calibrating a device such as a camera, projector, or both using a video stream. The device undergoing calibration is coupled to a computing device and configured to acquire video comprising a plurality of images. These images, at least some of the time, include targets having known characteristics present in an environment. From these acquired images calibration data comprising parameters such as intrinsic parameters, extrinsic parameters, or both, may be determined. The calibration data may be embedded or otherwise associated with the video stream as calibration matrix metadata.
