Camera Calibration

Before activating the system, the system needs to be calibrated.

The calibration has two steps:

  1. Calibration board detection.
  2. Lit calibration sphere detection.

  1. Open the AR51 management system in a browser
  2. Camera check
  3. Place the provided calibration board
  4. Start the camera calibration
    1. Open at least one camera feed
    2. Click on the “Start Cam Calibration” button
    3. Switch on the calibration sphere
    4. Move around the room holding the calibration sphere
  5. Monitor the progress in Mocap Studio

Open the AR51 management system in a browser

Using the web interface you can monitor the system and activated the calibration process.

Camera check

Check that all cameras appear and that the feed from each camera works.

Use can use the feed to check that all cameras are pointing to the capture area.
And, that there is good coverage of the area.

Poor coverage can lead to poor capture quality.

Place the provided calibration board

Place the provided calibration board in the middle of the capture area and make sure that is fully visible by as many cameras as possible.

Start the camera calibration

Open at least one camera feed

The feed from the camera should reflect the various stages in the calibration process.

Click on the “Start Cam Calibration” button

Once the calibration board detection is completed the images in the camera feed will turn darker.

Switch on the calibration sphere

Once the feed goes dark, switch on the provided calibration sphere.

Make sure your light bulb emits a strong white light (at least 1800 lumen). Using yellow, warm light can result with a bad calibration score.

Move around the room holding the calibration sphere

Do not run while holding the sphere.
Make sure you move around the entire capture area.
Try to vary the height of the calibration sphere.
Variation in height means a better quality.

Use the progress bar in the management system to monitor the progress of the calibration.

Monitor the progress in Mocap Studio

You can use “Mocap Studio” to view the movement of the ball in 3D

Once the calibration is completed you can view the 3D avatars in “Mocap Studio”.
