Is your feature request related to a problem? Please describe.
During some experiments, lense distortion or not being perpendicular to the laser sheet makes measurements inaccurate.

Describe the solution you'd like
Use the instructions based off of the article Distortion correction of two-component - two-dimensional PIV using a large imaging sensor with application to measurements of a turbulent boundary layer flow at Re = 2386. The calibration script should be placed in its own file or in OpenPIV.tools.
