What is the equivalent to-and-from source-and-destination coordinates for those lenses? Again, more code than just mathematical formulae please I've found this description of how to generate a fisheye effect, but not how to reverse it. I also see that my undistortion is imperfect on some lenses - presumably those that are not strictly linear. What is the inverse, in code in the style of the converting functions I posted? How do you calculate the radial distance from the centre to go from fisheye to rectilinear? I actually struggle to reverse it, and to map source coordinates to destination coordinates. I discovered how to map a linear lensfrom destination coordinates to source coordinates.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Converting a fisheye image into a panoramic, spherical or perspective projection Not a cheap solution, but certainly worth considering if you need the ultra-wide angle, but don't care for the distortion.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Ken Rockwell wrote a review of DxO Optics that illustrates converting fisheye to rectilinear photos. In 'General' you can set the degree of correction with the slider and check in 'example' click 'OK' in file 'Export as' Here I choose as jpeg. In Filters, click on distortion and choose lens distortion. Click in file on open and add the photo that you want to correct.

This is a free and very extensive software, easy to use. It's using a proprietary remapping that is not simple rectilinear defishing, which gives results some find more pleasing. This may be easier to use and suss than going into the overkill of using Hugin or PTGui off-label, as both those apps are centered around panorama stitching.ДЄnother popular tool for defishing is the commercial Fisheye-Hemi Photoshop plug-in. But there is one PT frontend that is dedicated solely to the task of lens correction, which is PTLens. However, since not everyone is a command-line jockey, there are also a number of Panorama Tools GUI front-ends to consider that can do the same thing, such as Hugin or PTGui. The Panorama Tools open source suite of command line tools includes the capability of lens correction-basically building a profile on the fly.

If you're post-processing with Adobe software or software that understands Adobe's lens profiles, the easiest way to correct for the Sigma 8mm circular fisheye is to simply use a lens profile.ДЄccording to the Sigma websiteboth Sigma's 4. For defish the photos you can also use Hugin it's free. Can you recommand me a software for doing this job? I shoot using Sigma 8mm lens and I would like to be able to obtain a normal image out of that.
