Calibrating the Accelerometer

The NavVis VLX automatically calibrates the accelerometer when powered on. The following screen is only displayed if there is a notification that asks you to manually calibrate the device. This manual calibration screen could display for example because the device was moved during the calibration.

The accelerometer calibration is an important step to achieving accurate scans. However, if the calibration continues to fail, you can skip this step, but the results will slightly less accurate.

Caution: Do not move the device during this procedure. If the device is moved during this step, Point cloud quality may be significantly reduced.

1. Place the device on a level surface.

2. Tap Calibrate.

   

3. Wait for the progress bar to reach 100%. This should take about 20 seconds. If you want to cancel the calibration, tap Cancel.

4. The user interface displays a message indicating that the calibration is successful.

5. Put on the device.

6. Follow the instructions on the user interface to initialize SLAM.
