The Analyzer Working view. This view provides you with the ability to view your
analyzed scene using a working camera, which you can modify to view the scene

without modifying the tracked virtual camera. This can be helpful to orbit the scene
in order to view the depth of 3D points, for example.
NOTE The Analyzer views also display shading in the image window, if the setting is activated in the Action Setup
menu.
Analyzer View box Select which analyzer to display in the image window.
If your scene has multiple analyzers, use the Analyzer View box to select which analyzer to display in the

Working view.
Camera Tracking
You can perform automatic 3D tracking based on the camera properties of the device used to acquire the
image sequence you want to track. You can specify these properties, or let the analyzer automatically detect
the best solutions for the analysis. Even if you want to perform object tracking on specific moving areas of
the scene, you also start with an analysis using camera tracking to create a properly tracked camera.
TIP To improve the results of the track, consider adding 2D manual trackers (page 648) either pre- or post-process.
To create a 3D camera track:
1 Add an Analyzer Mono or Analyzer Stereo node, as explained in Adding an Analyzer Node (page 649).
2 In the Camera Tracking menu, set Analysis options. For example, decide if you need to use a matte or
GMask in the analysis. In an image sequence of a busy street, you can create a matte or mask of moving
elements (such as cars and people) to isolate this area from the analysis. See
Analysis Settings (page
657) for details of each Lens Correction, Constraints, and Camera setting.
