Troubleshooting capture

  • Symptoms

  • There are no visible markers in the 2D view window in the preview mode.

  • Resolutions

    • Check that the cameras are focused.

    • Check that the aperture is open enough.

    • Check the Exposure time and Marker threshold settings, see chapter Tips on marker settings in QTM.

 

  • Symptoms

  • The markers in the 2D view are too small (check the size in the Data info window).

  • Resolutions

    • Check that the aperture is open enough.

    • Move the camera system closer to the markers.

    • Change to a larger marker on the measurement object.

    • Check that the marker is not worn, if it is replace it with a new one.

 

  • Symptoms

  • The markers in 2D are not stable.

  • Resolutions

 

 

  • Symptoms

  • There are fewer markers in the 3D view than in the 2D view.

  • Resolutions

    • Check that the Bounding box setting on the 3D Tracking page in the Project options dialog are large enough.

 

  • Symptoms

  • QTM is waiting for external trigger, but no trigger is connected.

  • Resolution

    • Check that the Use external trigger option is not selected on the Synchronization page in the Project options dialog.

 

  • Symptoms

  • A camera is indicated as Not use for tracking in the 2D view and the 3D view window.

  • Resolutions

    • The camera is deactivated on the Linearization page in the Project options dialog. Activate the camera and retrack the measurement if you have already made measurements, see chapter Reprocessing a file.

      If the camera was deactivated during the calibration, the calibration must be reprocessed if you want to use the camera, see chapter Recalibration.

 

  • Symptoms

  • There are error messages saying that the camera did not reply three times in a row.

  • Resolutions

    • Check that you are using the built-in wired Ethernet. Sometimes the communication does not work with Ethernet adapters.

    • Check the Ethernet cables so that they are not broken.

    • Reboot the camera system.
