CreateRectificationMap_Basic


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.
