On the Calibrate tab, in the Manage Camera Calibration section, you can reset, load, or save camera calibrations that define settings for the Vicon cameras in your Tracker system.

During the Vicon camera calibration process, Vicon Tracker creates a calibration parameters (.xcp) file. The changes in the .xcp file are automatically written to the calibration file, which overwrites the current file. If you want to be able to load the previous calibration in later, you must save it.

Changing a camera calibration can be useful in the following circumstances:

  • To undo a poor calibration change.
  • To compare calibration changes.

To manage camera calibration files in Tracker:

  • On the Calibrate tab, go to the Manage Camera Calibration section and click the required button:

    Auto Number Cameras Enables you to quickly number the currently connected Vicon cameras in ascending order, according to their position in the capture volume. To obtain useful autonumbering, you normally auto-number the cameras at some point after you have aimed (and calibrated) the cameras.
    Automatic numbering starts with the camera that is furthest from the volume origin. The cameras are then numbered in a clockwise direction around the volume. If your cameras are positioned at different levels, the cameras in the level that contains the most cameras are numbered first.
    ResetRemoves all non-existing cameras, clears the calibrated position for existing cameras, and reverts all calibration parameters to their default settings. This enables you to recalibrate the system from a clean starting point.
    LoadDisplays the Choose a file dialog box, from which you can navigate to and select the required .xcp file and click Open.
    SaveSaves the current calibration.
