Recording Your Calibration
Updated this week

The purpose of the calibration is for the system to understand the position of the cameras with respect to the environment they are within. The system does not require actor calibrations, it will use the camera calibration to determine the bone lengths of the actor(s) automatically.

To capture a calibration:

  1. Hit record.

  2. Stand in the centre of the capture area.

    1. Clap 3 times above your head clearly, ensuring it is sufficiently louder than any background noise. (Note - this isn’t necessary if your cameras are synchronized)

    2. Stand in a Y pose for 2 seconds, then walk from the middle of the capture area to the edge of the volume in front of each camera, facing the camera at all times. Move in a natural motion, pause at each camera and return to the centre while still facing the camera.

    3. Repeat this motion walking to each camera, then backwards to the centre, before moving on to the next.

    4. If using less than 4 cameras, walk around the perimeter of the volume to ensure the system has an accurate understanding of the shape of the capture volume. (The perimeter will be used to ensure only the desired actors are tracked during action takes,

  3. Now finish the recording.

  4. At this stage, we recommend measuring the height of your actor and noting it down, you'll need it later when you process the calibration! Their height should not include the footwear they are wearing.

  5. We always recommend doing an extra calibration at the end of your session, just in case a camera was moved during the session.

💡 Make sure only the actor (i.e no other people) are in the capture area during the calibration otherwise the system may track the wrong actor.

Make sure that the actor moves in a natural motion and aims to cover all of the capture volume within the capture area.

If the camera are moved (even slightly) at any point during the shoot, a new calibration will be required for optimal results.
