Because the undistortion is done across two steps, the stage 2 error log file can be used to
gauge the errors in the final trajectory estimate.
When all control points are active, there is no way to tell how big the distortions along the
trajectory are in-between control points. Inactive control points, however, have no effect on the
new trajectory estimate; almost as if they were not there. But because these inactive control
points
are there, and you know their poses, you now have points where you can compare the
distorted trajectory estimate with real, measured control points.
The Error Log File for the second stage is
datasets_proc/<dataset_name>/anchors_verification.log
.
Stage 3: Optimization
For the Optimization stage, it is best to activate all the control points, so that the final trajectory
estimate is as accurate as possible. The same undistortion algorithm runs again, minimizing the
remaining errors at all active control points.
