Abstract
Provided is a method of processing images. The method may include obtaining a plurality of radially-distorted images captured from one location in different directions, the plurality of images each having a field of view, and neighboring images among the plurality of images having overlapping fields of view. The method may further include reducing relative distortion of portions of the neighboring images in the overlapping fields of view of the neighboring images, matching features between the reduced distortion portions of neighboring images in the overlapping fields of view, and storing in memory data indicative of matched features.
