You can customize the appearance of the Tracker window to suit your preferences, using any of the following procedures. Tracker maintains these settings until you adjust them again.
Change the position of panels
In Tracker, you can position the panels to suit your way of working.
To move panels, drag them by their title bars and drop them into place using the guides that overlay the main window:
If you prefer, instead of docking the panels as described above, you can leave panels floating in an independent window.
Hide and display panels
In addition to changing the position of panels (see Change the position of panels), you can also hide some panels, to give you more space in which to work.
To hide/redisplay a panel:
On the title bar of a docked panel, click the Pin button.
The panel is hidden as a vertical tab along an edge of the main window.
If you hide multiple panels, they are tabbed vertically along the edge of the main window.
To re-display a pinned tab:
- Click the required tab on the edge of the main window.
The panel is displayed in a floating window.
- To dock it again, click its Pin button.
Expand and collapse panel sections
Within each panel, you can expand and collapse sections, to make it easier to access the controls you want to use.
Click the upward-pointing arrow
Click the downward-pointing arrow
To help you find the controls, panels also let you show and hide Advanced settings, and where applicable, you can set the values to their defaults.
Customize views and layouts
Tracker provides you with a number of ways to customize both what you view in the Tracker Workspace and the layout of the windows. You can change and customize the view to suit your way of working.
Set appropriate View Filters
While you're working with Tracker, you can set the View Filters to give the most useful view of your data. View Filters are available for 3D View, Cameras, and Object views.
The View Filters for the 3D View include options for object tracking.
Your settings are automatically saved, so that you can easily re-use them for different workflows.
The view filter presets are stored in the view presets file, by default:
The current view filter preset is stored in the view file, by default:
Change camera orientation detection
View frames in the Cameras view can be rotated to match their physical orientation, so that up in the image matches up in the real world. The orientation is determined from the camera calibration if available, otherwise the accelerometer on board the camera is used.
This option is enabled by default.
To turn on or off camera orientation detection:
- In the Cameras view, click View Filters.
- In the 2D Data section, select or clear Show Orientation.
- To choose whether to snap to 90° increments, ignoring smaller rotations, select or clear Snap to 90°.
Display the number of selected markers
To quickly check that all markers on a particular target are visible, you can select an option in the 3D View to show the number of markers currently selected.
To display the number of selected markers:
- In the 3D View, click View Filters.
- In the Overlays section, select or clear Selected Marker Count.
At the bottom right of the view pane, the Marker Selection count is displayed. If no markers are currently selected, a zero is displayed.
As you select markers, the Marker Selection counter changes to display the number of selected markers.
Save your window layouts
In addition to using the supplied Default tracking, Capture and Camera Calibration layouts, you can save your own customized layouts of the workspace and panels. This enables you to quickly switch between layouts when either setting up the system or object tracking.
The settings that are saved are those affecting panel visibility, geometry and settings that only affect the Tracker UI (graph settings, 3D View/Cameras View Filters settings and the last opened folder paths).
To save or change the window layout, on the right of the menu bar, click View Settings and select the required option.
Custom layouts are saved by default to:
Loading a view file also loads the graph settings stored in that view file, replacing whatever graph settings you have configured in your current view.
Search for properties in the Processing panel
The Processing panel is not displayed in the Tracker default layout. To display it:
- From the View menu, select Processing.
The Processing panel provides a search facility and other controls that determine the visibility of the component properties.
To use the search, in the Search filter field at the top of the panel, enter the first few letters of the property you want to find.
