WebThis means that \(\left\) can be either an affine or perspective transformation, or radial lens distortion correction, and so on. So, a pixel value at fractional coordinates needs to be retrieved. In the simplest case, the coordinates can be just rounded to the nearest integer coordinates and the corresponding pixel can be used. WebBut the use of super-wide angle fish-eye lenses causes strong distortions in the resulting images. A method for the correction of fisheye distortion using only single images and linearity of imaged objects is presented. Spherical projection is a simple and effective method to transform a fisheye image to a perspective projection image.
