Device Calibration

By default, every device has its own coordinate system.
By performing device calibration, all devices agree on a common coordinate system.

3. Inside VR: Open an application on a device that has the AR51 SDK
4. Select your device on the AR51’s web-based management system and start calibration
5. Calibrate the device
   1. While in the VR application, lift both your hands so they are fully visible to the device’s cameras
   2. Move slowly across the capture area while moving your hands
   3. Character should “snap” onto your body (in VR)

Locate the server IP

To perform device calibration you need to enter the web-based management system of the server.

You can find the ip on the server’s GUI top left corner.

Note that the ip displayed in the image “192.168.0.197” is probably different from yours.

Open the AR51 Management System in a Browser

Enter the IP of the server in your browser. Using the web interface, you can monitor the system and activate the calibration process.

Inside VR: Open an application on a device that has the AR51 SDK

In Oculus Quest, “Developer apps” are usually located under “unknown sources” inside the oculus quest

Once the app is open on the device, you should see the device on the devices panel.

Select your device on the AR51’s web-based management system and start calibration

1. Select the device you wish to calibrate from the device panel.
2. You should see a blue box that indicates that the device was selected.
3. Press the “Device Calibration” button in the management system.

Calibrate the device

While in the VR application, lift both your hands so they are fully visible to the device’s cameras

The VR device should see your hands. It is best if your hands are in front, between chest and head high.

Move slowly across the capture area while moving your hands

Do not wave your hands too fast. Move them at a relaxed speed.
Moving too fast can produce poor calibration quality.

Character should “snap” onto your body (in VR)

You should see the character “snap” into place after a short while. This does not mean the calibration is over. You should still move around the capture area to improve the calibration.
