Abstract
In panoramic video captured by a fisheye camera (e.g., for use in the remote operation of mobile equipment), there is a trade-off between the field of view and the level of distortion correction. In particular, to avoid the video from be disorienting, distortion correction is required. However, distortion correction applied to a very wide field of view results in an unnatural appearance of objects in edge regions, such that the image frames of the video must be cropped. A method is disclosed that varies the level of distortion correction that is applied to pixels in each image frame based on a position of those pixels in the image frame, such that less distortion correction is applied to pixels closer to edges of the image frame. This enables a very wild field of view, while preventing the unnatural appearance of objects near the edges of the image frame.
