If you're "just" doing AR, it will only render the elements that have to be overlaid onto the real video.
PING PONG EYEBALLS GENERATOR
A serial cable between the lens grip and processor box adds your lens data (zoom, focus, iris, etc), then all those coordinates are shoved down the network to the character generator (graphics PC).Ī graphics system like Ross Voyager or Viz Virtual Studio uses the coordinates Mo-Sys is vomiting at it to place a virtual camera in the virtual set. By plotting the stickers it sees against a known map, and watching the parallax scrolling of the different layers, it can work out where in physical space the camera is and what angle it's pointed at. (For example, on a lighting grid, ductwork, and the physical ceiling of a studio space.) A camera module positioned above the camera's sensor flashes pulsed IR at the ceiling, and monitors the constellation overhead. Instead of QR code plates (which could be seen in AR applications), that system uses a constellation of retroreflective stickers placed in an irregular pattern at different heights all over the ceiling. I actually have some experience with the kind of professional broadcast virtual set solutions Linus touched on.Ĭamera tracking can be done with a rig like Mo-Sys StarTracker.
