Customizing Tracking Bounds

Motive can have restrictions placed to customize tracking. Infrared sources, such as a LED Stringer of a BTBeacon, that are outside these restrictions will not be acknowledged by the system.

Motive 2

Limiting Tracking Within Boundaries

In Motive, as an optional step, you can create a boundary around the Space. The boundary commands the system to ignore infrared sources outside this boundary. BTBeacon positional data found outside the boundary will not be sent downstream to other applications.

To define boundaries, you need to measure how far the origin of the Space is from the intended boundary in the Space. This is required for each axes (XYZ). The origin of the Space should be the same origin as the duplicate Space made in WYSIWYG.

Attention: In Motive, the Z axis represents length and the Y axis represents height. For the rest of BlackTrax the Z axis represents height and the Y axis represents length. +X also becomes -X in Motive.

Note: Be aware of the -Y setting for your Space. If the origin of the Space is elevated and tracking occurs below the origin, ensure the value can cover the intended tracking area.

To set the tracking boundary of the space

  1. In Motive, change the layout to Running preset.  From the Layout menu, choose Running.
    • Tip: You may click the drop-down box at the right-hand side of the main toolbar and click Running from the drop-down menu of layout presets.
  2. In the Application Settings window, click the Live Reconstruction tab.
  3. On the  Live Reconstruction tab, click the Advanced Options heading to open the Advanced Options section.
  4. On the Advanced Options section, click the Reconstruction Bounds heading to open the Reconstruction Bounds section.
  5. On the Reconstruction Bounds section, click the Visible Bounds drop-down menu and select True
    • Result: The set tracking boundary of Space is displayed in the Perspective View window. The set tracking boundary of the Space will not be displayed in the Perspective View window if False is selected.
  6. Set the Minimum X (meters) field to the distance from the origin of the Space to the intended boundary on the negative (-) X axis (width).
  7. Set the Maximum X (meters) field to the distance from the origin of the Space to the intended boundary on the positive (+) X axis (width).
  8. Set the Minimum Y (meters) field to the distance from the origin of the Space to the intended boundary on the negative (-) Y axis (height).
  9. Set the Maximum Y (meters) field to the distance from the origin of the Space to the intended boundary on the positive (+) Y axis (height).
  10. Set the Minimum Z (meters) field to the distance from the origin of the Space to the intended boundary on the negative (-) Z axis (length).
  11. Set the Maximum Z (meters) field to the distance from the origin of the Space to the intended boundary on the positive (+) Z axis (length).
  12. Close the Reconstruction Properties window.
    • Result: The boundary in your Space is defined. Tracking is only possible inside this boundary.
  13. To save as a profile, select Save Profile or Save Profile As from the File menu.

To set BlackTrax BTSensor beam length

Attention: The Maximum distance should be the largest distance between a BTSensor and the furthest tracking boundary. The minimum distance should be the shortest distance between a BTSensor and the closest tracking boundary.

Note: After BTSensor calibration, Motive automatically determines these values with estimates of acceptable tracking distances. You may override these values at any time, but if you re-calibrate these fields will be re-populated.

  1. In Motive, change the layout to Running preset. From the Layout menu, choose Running.
    • Tip: You may click the drop-down box at the right hand side of the main toolbar and click Running from the drop-down menu of layout presets.
  2. In the Application Settings window, click the Live Reconstruction tab.
  3. On the Reconstruction Settings section of the Live Reconstruction tab,  set the Maximum Ray Length field to the desired maximum length.
  4. On the Reconstruction Settings section of the Live Reconstruction tab, set the Minimum Ray Length field to the desired minimum length.
  5. To save as a profile, choose Save Profile or Save Profile As from the File menu.
    • Result: The beam length of BTSensors will be set. BTSensors will only acknowledge BTBeacons within this range.
    • Tip: You can also export the BTSensor calibration data.  See To export a calibration CAL file.

To set BlackTrax BTSensor beam length

Attention: The Maximum distance should be the largest distance between a BTSensor and the furthest tracking boundary. The minimum distance should be the shortest distance between a BTSensor and the closest tracking boundary.

  1. Open the Reconstruction Properties window. To open the window, from the View menu, choose Reconstruction Properties.
  2. In the Reconstruction Properties window, in the Point Cloud section, under the Options heading set the Minimum Ray Length field to the desired minimum length.
  3. Set the Maximum Ray Length field to the desired maximum length.
  4. Save the changes to the project file. To save, from the File menu, choose Save Project.
    • Result: The beam length of BTSensors will be set. BTSensors will only acknowledge BTBeacons within this range.
    • Note: After BTSensor calibration, Motive will automatically determine these values with estimates of acceptable tracking distances. You may override these values at any time, but if you re-calibrate these fields will be re-populated.

To set the tracking boundary of the space

  1. Open the Reconstruction Properties window. To open the window, from the View menu, choose Reconstruction Properties.
  2. In the Reconstruction Properties window, in the Point Cloud section, under the Reconstruction Bounds heading set the Bound Reconstruction field to True.
  3. Set the Minimum X (meters) field to the distance from the origin of the Space to the intended boundary on the negative (-) X axis (width).
  4. Set the Maximum X (meters) field to the distance from the origin of the Space to the intended boundary on the positive (+) X axis (width).
  5. Set the Minimum Y (meters) field to the distance from the origin of the Space to the intended boundary on the negative (-) Y axis (height).
