Instance Property

inverseLensDistortionLookupTable

A map of floating-point values describing radial distortions for use in reapplying camera geometry to a rectified image.

Declaration

@property(nonatomic, readonly) NSData *inverseLensDistortionLookupTable;

Discussion

If you've rectified an image by removing the distortions characterized by the lensDistortionLookupTable property, and now wish to go back to a geometrically distorted image (for example, to render visual effects into the camera image or perform computer vision tasks such as scene reconstruction), use this inverse lookup table.
