--- title: "Camera calibration properties" canonical: "https://help.vicon.com/space/Tracker41/14323626/Camera%20calibration%20properties" format: markdown --- In the **C****amera Calibration** panel, you can change the following properties listed in this section. > Macro (scroll-only) > > > Macro (toc) > Macro (excerpt-include) > Macro (scroll-pagebreak) ## > Macro (inline-media-image) Masking section > Macro (scroll-tablelayout) | **Control** | **Description** | | --- | --- | | **Slack** | Specify the number of additional pixels to mask around the detected edges. Range 0 to 4.
Default: 1 px | | **Clear Previous Masks** | When selected, previous masks are cleared at the start of the masking process.Default: Selected | | **Mask All** | Auto-mask all cameras | | **Selected** | Auto-mask selected cameras | | **Cancel** | Cancel the current auto-masking operation and restore the previous camera masks. For this button to be enabled, manual masking must be in progress. | | **Manual Mask Paint** | Click to start manual masking. For this button to be enabled, at least one camera must be contributing data. | | **Cancel** | Cancel the current masking operation and restore the previous camera masks. For this button to be enabled, manual masking must be in progress.
This Cancel button is located next to the **Manual Mask Paint** button. | > Macro (scroll-pagebreak) ## > Macro (inline-media-image) Wand Wave section > Macro (scroll-tablelayout) | **Control** | **Description** | | --- | --- | | Wand list | Select the calibration object to be used during the camera calibration process. By default, the selected object is also used for setting the volume origin. If required, you can select a different object for setting the origin. To do this, ensure the Advanced properties are displayed and in the **S****et Volume Origin** section, select the required object. Default: Active Wand v2 | | **Auto Stop** | When selected, Tracker automatically stops camera calibration when sufficient data (defined by the **Auto Stop Minimum Frames **parameter) has been collected.
This is an advanced parameter. Default: Selected | | **Auto Stop Minimum Frames** | With auto stop selected, the minimum wand coverage (in number of frames) required per camera before Tracker automatically stops calibration. Range 100 to 10,000.
This is an advanced parameter. Default: 1000 | | **Wand Ratio Tolerance** | Tolerance of the distance between the markers on the wand (expressed as a ratio), to enable it to be labeled in 2D. Range 0.01 to 0.50. Default: 0.2 | | **Wand Straightness Tolerance** | Tolerance in alignment of wand markers (relating to the maximum angle allowed between markers) to enable it to be labeled in 2D. Range 0.01 to 0.50. Default: 0.2 | | **Wave All** | Start collecting wand wave data for camera calibration. At least two optical cameras must be contributing data. | | **Selected** | Start collecting wand wave data for calibrating selected cameras. At least one camera must be selected for this button to be active. | | **Cancel** | Cancel the current camera calibration operation. | ## > Macro (inline-media-image) Volume Setup section > Macro (scroll-tablelayout) | **Control** | **Description** | | --- | --- | | ***Set Volume Origin section***** ** | | Synchronize L-Frame > Macro (inline-media-image) | Click to control whether the L-Frame is synchronized with the wand wave calibration object. Disable to select a different L-Frame.
Default: Synchronized | | **Perform Rescale** | Rescales the calibration using the dimensions of the selected L-Frame object. For more information see [Scale calibration and set a fixed origin](https://vicon-help.atlassian.net/wiki/pages/createpage.action?spaceKey=ED&title=Scale%20calibration%20and%20set%20a%20fixed%20origin).Default: Cleared | | **Start Set Origin** | Click to start collecting data to set the volume origin. For this button to be enabled, at least two calibrated optical cameras must be contributing data. | | **Cancel** | Cancel the current Set Origin operation. For this button to be enabled, Set Origin must be in progress. | | ***Set Floor Plane section***** ** | | **Height offset (mm)** | Set the amount in millimeters by which to lower the floor plane. Default: 7 mm | | **Start Set Floor Plane** | Click to start collecting data to set the floor plane. For this button to be enabled, at least two calibrated optical cameras must be contributing data. | | **Cancel** | Cancel the current set floor plane operation. For this button to be enabled, Set Floor Plane must be in progress. | | * ****Set Floor Grid section**** * | | **Min X (mm)** | Set the minimum x-coordinate of the floor plane in millimeters. Default: -3,000 mm | | **Max X (mm)** | Set the maximum x-coordinate of the floor plane in millimeters. Default: 3,000 mm | | **Min Y (mm)** | Set the minimum y-coordinate of the floor plane in millimeters. Default: -3,000 mm | | **Max Y (mm)** | Set the maximum y-coordinate of the floor plane in millimeters. Default: 3,000 mm | | * **** Auto Number Cameras section**** * | | **Auto Number Cameras** | Click to automatically number the cameras (see [Autonumber cameras](https://vicon-help.atlassian.net/wiki/spaces/Tracker41/pages/14322550/Set+up+the+volume)). | ## > Macro (inline-media-image) Calibration Healing section | **Control** | **Description** | | --- | --- | | **Start Recover Camera pose** | Click to start collecting track data generated by moving markers to recover the position of the selected camera(s). You cannot recover the position of a non-contributing camera. | | **Cancel** | Cancel the current Recover Camera Pose operation. For this button to be enabled, Recover Camera Pose must be in progress. |
