To determine the direction the subject is facing, the video tracker will look for specific colored targets (generally LEDs) in a specific configuration. The Direction Finding Configuration dialog allows you to make adjustments as to what colors are being tracked and where those targets are in relation to the subject. Make sure that the adjustments you make here are correct, as incorrect values will give erroneous direction values.
You can launch the Direction Finding configuration by pressing the Configure button on the video tracker acquisition entity properties.
Direction Finding Settings
|
|
| 1. Head Direction Offset | This value is set to adjust the head angle in degrees for tracking LEDs that are not centered on the subject. For an example of how this value is used, see the documentation for the -SetDirectionOffset command. |
| 2. Direction Indicator | The point of the arrow represents the direction your subject is facing, relative to the LED locations. |
| 3. LED | These images indicate the location and color of the LEDs that cheetah is currently tracking. The location is fixed based on the LED configuration you have selected. 2LED mode is pictured in the example. |
| 4. LED Color Selection | When in 2LED tracking mode, you may specify the color you want each LED to be. The HS-54 configuration has fixed colors that cannot be changed. Cheetah supports the following LED colors:
|
| 5. OK Button | Unlike most other settings in Cheetah, the changes made for direction finding are not immediately applied. You will need to press OK in order to apply the changes.
|
| 6. Cancel Button | Unlike most other settings in Cheetah, the changes made for direction finding are not immediately applied. If you wish to discard all changes that you have made, you can click cancel. Closing the dialog by clicking the X in the upper right corner is identical to clicking the cancel button.
