Tracker enables you to quickly correct a camera whose position has changed due to having been bumped or moved. To do this you use:

- Any visible markers in the volume and
- The **Recover Camera Pose** feature

You can use this feature in conjunction with the bump notifications, where you can heal cameras identified as having been knocked by using Recover Camera Pose.

> ⚠️ **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 this reason, we recommend 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 [Calibrating Vicon cameras](https://vicon-help.atlassian.net/wiki/spaces/Tracker41/pages/14321583)).

## Correct a bumped or moved optical camera

The following procedure corrects a bumped optical camera (Valkyrie, Vantage or Vero):

1. In the **System** panel, select the camera that was bumped or moved.
2. In the **Camera Calibration** panel, click **Start Recover Camera Pose**.
3. In the volume, move the markers in front of the affected camera.
  In the **3D View** and **Cameras** view, you can see orange trails as the system determines the offset between the camera and the rest of the calibration.
4. When enough of the view and the camera's frustum have been covered (indicated by orange trails showing the path of the markers in the affected camera view, as shown above), click **Stop Recover Camera Pose**.
5. To confirm that the camera has been successfully healed, check that the camera has good Centroid Connectivity and Image Error, either in the **System Health Report** or via the icons in the **Cameras** view (see [Understand System Health Report](https://vicon-help.atlassian.net/wiki/spaces/Tracker41/pages/14323303) and [About the Cameras view](https://vicon-help.atlassian.net/wiki/spaces/Tracker41/pages/14320956)).

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 the affected camera again. For information, see [Mask cameras](https://vicon-help.atlassian.net/wiki/spaces/Tracker41/pages/14320612).
