Fisheye image correction
WebMar 30, 2024 · Distortion rectification is often required for fisheye images. The generation-based method is one mainstream solution due to its label-free property, but its naive skip-connection and overburdened decoder will cause blur and incomplete correction. First, the skip-connection directly transfers the image features, which may introduce distortion and … WebMar 19, 2015 · possible duplicate of correcting fisheye distortion programmatically – rayryeng Mar 19, 2015 at 6:03 Standard fisheye correction is to determine points that are collinear in the image then use these to compute the distortion function to rectify the image. I've also marked a link as a duplicate so you can take a look. – rayryeng Mar 19, 2015 at …
