Switch to the Solve control panel . The solver panel affects the camera or moving object currently listed as the Active Tracker Host. Select the solver mode as follows:
Auto : the normal automatic 3-D mode for a moving camera, or a moving object.
Refine : after a successful Auto solution, use this to rapidly update the solution after making minor changes to the trackers or coordinate system settings.
Tripod : camera was on a tripod, ie a “nodal” shot, track pan/tilt/roll(/zoom) only.
Refine Tripod : same as Refine, but for Tripod-mode tracking.
From Seed Points : use six or more known 3-D tracker positions per frame to begin solving (typically, when most trackers have existing coordinates from a 3-D scan or architectural plan). You can use Place mode in the perspective view to put seed points on the surface of an imported mesh (or vertex of a lidar mesh). Turn on the Seed button on the coordinate system panel for such trackers. You will often make them locks as well. If your data is excellent, you may need only four points.
From Path : when the camera path has previously been tracked, estimated, or imported from a motion-controlled camera. The seed position, and orientation, and field of view of the camera must be approximately correct. (You should still set up a coordinate system for the resulting solve, using tracker positions or the seed path!)
Indirect : to estimate based on trackers linked to another shot, for example, a narrow-angle DV shot linked to wide-angle digital camera stills. See Multi-shot tracking.
Individual : when the trackers are all individual objects buzzing around, used for motion and facial capture with multiple cameras.
Disabled : when the camera is stationary, and an object viewed through it will be tracked.
The solving mode mostly controls how the solving process is started: what data is considered to be valid, and what is not. The solving process then proceeds pretty much the same way after that, subject to whatever constraints have been set up.
