Example: Nonlinear Calibration

This example illustrates how to use a calibration grid to calibrate an image for nonlinear distortion, and correct the image so you can perform accurate measurements on it in real world units.

This example loads a template image of a grid that is used to calibrate a system, uses the image loaded to learn the calibration from the grid, corrects a distorted image with the learned calibration information, and measures distances on the corrected image.
