# inverseLensDistortionLookupTable

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

## Declaration

```swift
var inverseLensDistortionLookupTable: Data? { get }
```

## Discussion

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.
