Take shots of the grid at a known distance from the camera so you can determine the angular FOV. Find or make the grid with known spacing and good contrast, big enough so the GoPro can focus on it. To really be certain you are getting an accurate correction, take some images of a uniform grid.Leave the output projection as Rectilinear and play with the fixed pixels diameter. Check the link and try using the FOV data with a fisheye projection for the input image.Under the Field of View menu, you’ll see three options: SuperView, Wide, and Linear. You’ll find the details of the effect under Video Settings. I'm afraid I do not have one and can't give you the numbers you need (the most important number is the field-of-view 'FOV' of the lens). GoPro has the fisheye effect in all its latest models, beginning from GoPro Hero 5 to Hero 10. I was hoping some other GoPro users might jump in here with some Radial Distortion filter settings that have worked well.

Squeezing a trapezoid is simple in comparison to adjusting for a fisheye lens. One of these killer settings is the Field of View, aka FOV, which captures extreme wide-angle perspective resulting in fisheye distortion - straight lines bend outward from the center of the image or video - akin to barrel distortion.

I saw that you already have a method to correct for an improper video perspective the plane of the CCD not being in a parallel plane to the motion you are trying to measure. GoPro carves out the action cam niche by having every footage it records with distinctive look through its tons of settings. Modifying the video has a nice visual advantage. The Entaniya 250 Fisheye Lens is designed for use with Ribcage Modified GoPro cameras, delivering a 250 (horizontal) x 195 (vertical) angle of view on. Of course, I'd like to do it with some technical accuracy and I'd like to have a simple method to re-process the video to make things square.

Some people have suggested using video editing software to take out the fisheye effect.

Note: This option can be shown only when the video you shot has fisheye effect. Step 2: Now select Remove Fisheye option from menu and then hit OK. And the wide angle will make capturing some experiments more difficult. You need to follow these steps to complete your action: Step 1: First of all you need to import your GoPro camera output file with its original name and then hit the advanced settings option. The GoPro also comes with an array of mounting hardware to easily stick it anywhere. For physics experiments this makes it possible to do some cool things with relative motion by placing the camera on the moving object or on some other reference frame. The primary advantage of the GoPro is it's small size and high resolution. Re: Re: Can we correct for a fisheye lens? - Jul 3 2:21PM UTC
