Fisheye fov

WebJun 11, 2024 · Usually, the fish eye lens has a very short focal length (less than 15mm for a 35mm-size image sensor), but a large field of view (FOV). The latter can be as large as 180-degrees, giving the user a complete view of a scene. This extreme FOV produces a characteristic image with a large distortion. Figure 1: Fisheye image with large distortion. WebMar 6, 2014 · — Fisheye (FOV 180°): 4096x4096px — Fisheye (FOV 220°): 5000x5000px. I was happily surprised with the fact that upon increasing the FOV to 220°, then the final render resolution increases to 5k. This is possible because more footage is viewable at a higher FOV, and so you are effectively “squishing” more pixels into the fisheye image ...

Contrary to how it might seem, the lens focal length doesn’t refer to how long the lens is. Rather, it’s the distance from the image plane to the optical centerof the lens when the lens is focused at infinity. (The optical center is where all the light rays converge after passing through the lens elements.) (How to … See more Field of view is calculated through a bit of simple trigonometry.
