WebJan 1, 2024 · The transformation relationship between the perspective image and fisheye image is represented by a model. The two most commonly used models include the division model and polynomial model. The division model is as follows: (1) r u = r d 1 + ∑ i = 1 n k i r d 2 i - 1 We assume that the center of the image corresponds to the distortion center. http://www.paulbourke.net/dome/fisheyecorrect/
