Then take the beacon (hedgehog) and tilt it to each side towards the ground (about 6
times). Rotate a little. You need to achieve x y z values:
- When antenna directs down z ≈ - 1000 => antenna directs up z ≈ 1000
- So, one of the axis values always will be - + 1000. Others ⩽ 10 (preferably less 10,
but 25 is also permissible)
- Every time before calibrating the hedgehog click Pause
- Accelerometer calibrator will choose the best value for each axe. At the end click
Calibrate and close the window
- Calibration is needed to determine g value for each accelerometer axe
Start the system:
Setup the system as usual. It is described in paragraph Setting up the system.
After the ultrasound tracking has started, select the hedgehog in the Dashboard, go to
menu Interfaces (on the right) and enable Processed IMU data. After that, it is
recommended to bring the hedgehog to real estate and press the ZERO IMU button (right-
bottom) for additional sub-calibration of the gyro. After 5 seconds the hedgehog will begin
streaming the processed IMU data.
