Calibration
How do we figure out where the cameras are?
Currently, we're planning to add ad calibration method to the hub server which takes the most recent image from each camera (assuming it was sufficiently recent), and looking for a set of QR codes. Then, doing some math to figure out where the cameras are. Possibly involving bundle adjustment.
As for the camera intrinsics, we may be able to look them up from a database, or we may have to use a checkerboard.
