Abstract
Various technologies described herein pertain to rectification of a fisheye image. A computing system receives the fisheye image. Responsive to receiving the fisheye image, the computing system applies a first lookup function to a first portion of the fisheye image to mitigate spatial distortions of the fisheye image. The computing system also applies a second lookup function to a second portion of the fisheye image to mitigate the spatial distortions. The first lookup function maps first pixels in the first portion to a first rectilinear image corresponding to the first portion when viewed from a first perspective of a first virtual camera. The second lookup function maps second pixels in the second portion to a second rectilinear image corresponding to the second portion when viewed from a second perspective of a second virtual camera. The computing system then outputs the first rectilinear image and the second rectilinear image.
