Tracking in Stills Mode
In Stills mode, CameraTracker tracks the reference frames in the Source input and analyzes the input in two stages. Tracking defines the set of 2D feature tracks that correspond to fixed rigid points in the scene, then the solver calculates the camera path and projection that creates a 3D point for each reference frame.
Note: If you intend to remove lens distortion manually using a separate LensDistortion node, you should do that before you track the stills. See Working with Lens Distortion. Otherwise, set Lens Distortion to Unknown Lens before you solve the camera position to force CameraTracker to calculate the distortion.
