Camera calibration properties

In the Camera Calibration panel, you can change the following properties listed in this page.

Note
Some properties are available only when advanced properties are displayed (at the top right of the Properties pane, click Advanced Parameters

).

Masking section

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.

Wand Wave section

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 Set 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.

Volume Setup section

Control	Description
*Set Volume Origin section*
Synchronize L-Frame	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.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).

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.
