The purpose of the calibration is for the system to measure the Actor’s individual bone lengths before applying our body tracking algorithm to the motion takes.
It is important that the entire body and limbs are visible to each camera as you move around the capture area during this process.
Now that you are ready to calibrate, you'll need to follow these simple steps:
- Hit record on the your device (this will be specific to the camera system you are using, further explanation below)
- Stand in the centre of the capture area
- Clap 3 times above your head (this helps with the auto syncing in the platform, synced systems do not require this)
- Stand in a Y pose for ~2 seconds
- Whilst holding the Y-pose - from the middle of the capture area:
- Walk towards the marker at camera 1 in a natural motion, pause and return to the centre while still facing the camera.
- Repeat this motion to each of the markers at each camera, moving back to the centre afterwards before moving onto the next.
- Return to the centre after you have walked towards all cameras.
- Now hit stop on the device you are using (if using an iPhone, select New Scene when you are ready to begin filming a new scene.
- Make sure only the performer (i.e no other people) are in the capture area during the calibration otherwise the system will not perform adequately.
- Make sure that the performer moves in a natural motion and aims to cover all of the capture volume within the capture area.
- If the cameras are moved (even slightly) at any point during the shoot, a new calibration will be required for optimal results.
