When you’re happy with the features that you’ve tracked, you can solve the camera position. CameraTracker uses the tracking information to calculate the camera position and add position information to the tracked feature points in the Viewer.
In the CameraTracker properties panel, click Solve. The solver selects a subset of keyframes positioned relatively far apart so that there is sufficient parallax in the images to define the 3D points for the tracks.
When the solve is complete, the Viewer displays the tracked features with solve data applied.
