| Important You can use Recover Camera Pose to recover cameras that have been either bumped or moved. This process relies on having enough cameras within a calibrated system to act as a calibration anchor. For For this reason, it is recommended that it is run on only a small proportion of the cameras in a system. A single camera or a small number of affected cameras can be recovered with good results. If a larger number of cameras is affected, perform a full camera calibration instead (see Calibrate cameras ). |

The following procedure corrects a bumped optical camera (Vantage or Vero): for bumped video cameras, see Correct a bumped Vicon Vue video or SDI video camera.
- On the System tab, select the camera that was bumped or moved.
- On the Camera Calibration tab, select Start Recover Camera Pose.
- In the volume, have the subject move (or move the labeled object) in front of the affected camera.
In the 3D Scene view and Cameras view, you can see orange trails as the system determines the offset between the camera and the rest of the calibration.
- When enough of the view has been covered (indicated by orange trails that thickly cover the affected camera view, as shown above), select Stop Recover Camera Pose.
Scroll pagebreak - In the Cameras view, zoom in and check that the markers are now aligned, with no red warning symbols.
The camera is now correctly aligned with the rest of the system. Note that masking of the affected camera is not preserved, so for optimum results, you may need to mask this camera again. For information, see
