(Preliminary)
Ground Plane Calibration
Ground plane must be set after wand calibration.
Attention: The origin of the tracking space must be visible to a minimum of two calibrated BTSensors to get an accurate ground plane calibration.
To set ground plane calibration using the BT-1 Calibration Tool
- Attach the long arm module to the short arm/calibration wand module to assemble the BT-1 Calibration Tool into the Ground Plane. Use the dial on the long arm module gently to carefully fasten and avoid over-tightening.
- Snap-mount three fully charged Mini Beacons into the magnetic mounts on the Calibration Wand.
- Move the Mini Beacon from the middle of the wand to the long arm module.
- Place the Ground Plane on the origin of the tracking space. Use the knobs to level.
- Attention: The origin of the coordinate plane of the tracking space must be the same as the origin of its virtual representation in BTWYG and needs to match any origins in other integration devices connected to BlackTrax.
- Aim the short arm (half-meter) section towards the -X coordinate of the tracking space.
- Aim the long arm section towards the +Y coordinate of the tracking space.
- In Motive, on the Live Reconstruction tab of the Application Settings window, click Marker Labeling Mode and select Passive Markers Only.
- On the Ground Plane tab of the Camera Calibration window, set Vertical Offset (mm) to D45 mm.
- Click Set Ground Plane to apply ground plane calibration.
- Result: BTSensors will know their position in relation to the ground level and adjust accordingly in Camera View.
