| Module: | Calibration | 
|---|
Computes a spatial map for removing lens and perspective distortion directly from an image containing circles calibration pattern. Internally uses a pinhole camera model with polynomial lens distortion.
Applications
Quick and easy one-step calibration for basic removal of lens and perspective distortions.
