Fisheye to cylindrical
WebMay 2, 2024 · @PvDev Yes, but for that you won't really need to use rotation, you could just map it one on one. You only need a function that turns (x,y) from your fisheye image into (latitude, longitude), and then a function that turns this latitude, longitude into a pixel on your equirectangular output image (which is how geo_w_px was calculated). But ... WebCylindrical This is the result of projecting the panoramic sphere onto the surface of a cylinder: ... These projections simulate a fisheye lens. Both projections give the same result, but circular output is cropped to a circle while fullframe output is cropped to a rectangle. The field of view can be up to 360 degrees in both directions.

WebFisheye image projections aim to create a flattened grid where the distance from the center of this grid is roughly proportional to actual viewing angle, yielding an image which would … WebFisheye cameras are commonly used in applications like autonomous driving and surveillance to provide a large field of view ($>180^\circ$). However, they come at the cost of strong non-linear ...
WebIn fisheye image, when an object moves in XY plane at the same Z, its appearance changes as well. CNN is not immediately compatible with such a fisheye raw image. One way is to convert it into a cylindrical view. An object’s side and appearance remain the same as long as the $\rho$ distance keeps the same. WebInput sample fisheye image, 180 degrees. Perspective FOV=130, or Pannini d=0. Pannini d=1. The above illustrates the key property of these projections, the horizontal field of view of the Pannini projection on the right is the same as the perspective view on the left except the stretching on the extreme of the image has bee removed.
WebThe "basic Pannini projection" has just one parameter to adjust, namely "d" in the equations above. The effect of adjusting d is illustrated here noting that in each case the same horizontal FOV of 130 degrees is …
