Calibrate a selected camera

In addition to performing a full system calibration (see Calibrating Vicon cameras), you can calibrate or re-calibrate a single camera or subset of cameras. This enables you to add cameras to your system, or move calibrated cameras, and calibrate with a shorter wand wave, saving the time it takes to perform a longer wand wave for all the cameras.

To calibrate a subset of cameras:

1. With the moved or additional camera(s) positioned in the volume, in the System panel, from the Vicon Cameras list, select the relevant camera(s). These cameras may be flagged as Uncalibrated () if they are new.

   

2. In the Camera Calibration panel, in the Masking section, click Selected.

   The camera masking is updated to include the new or moved camera(s).

3. In the System panel, ensure the relevant camera(s) is/are still selected.

4. In the Wand Wave section:

   1. To ensure that only the wand wave for the selected camera(s) is/are required to meet the Auto Stop Minimum Frames value, make sure Auto Stop is selected.

   2. Click Selected.

      

5. In the volume, ensure that the person waving the wand does not stand too close to the new or moved camera(s), so that the wave can be captured by both the cameras of interest and the adjacent cameras.

   During calibration, the selected camera(s) is/are at the top of the Wand Count list until its wave is completed, when the list returns to the usual (device number) order.

   Calibration takes noticeably less time than the original full system calibration and the set origin step does not need to be completed.

   When calibration is complete, in the Vicon Cameras list in the System panel, the relevant camera(s) is/are flagged as connected and calibrated, with no other icons ().
