Fisheye lenses have become a staple in creative photography alongside other tilt-shift, telephoto zoom, and wide-angle lenses. This lens type applies a different distortion (or projection) mapping than a regular “pinhole” camera. In this tutorial, we’ll demonstrate how to undo this distortion and extract a “straight” … See more Essentially, we are interested in estimating the transformation involved in projecting a 3D point in space onto a projected 2D coordinate as follows: This transform can further be divided … See more Fisheye lenses are not all created equal. In order to know how to correct the distortion on a fisheye lens, it could be helpful to know what kind of fisheye we’re dealing with to better approximate its focal lengths ““. Fisheye … See more Alternatively, suppose we are trying to work with a specific camera, and we need to be very careful with approximating its resulting undistorted … See more Finally, we can quickly test this new knowledge on our browse using FisheyeGl(a library for correcting fisheye, or barrel distortion, on browser images that require JavaScript with WebGL).
