# Step Summary

The following 5 steps are performed during the calibration phase:

1. Find and label the calibration plate grid points (tile vertices or dot centers) in the calibration image.
2. Compute a (possibly nonlinear) calibration transform.
3. If nonlinear, generate an undistorted calibration image.
4. If nonlinear, select a destination rectangle and generate internal data structures for warping.
5. Compose the linear adjustment transform.

Each step's inputs and outputs are listed in the following sections. The following table defines which outputs become invalid when a given step's inputs are changed.
