Dewarping is the process of correcting the distorted, curved image produced by a fisheye lens to make it look more natural and usable. Fisheye lenses provide ultra-wide fields of view (180-degree or 360-degree), but the raw image appears highly curved and warped. Dewarping helps to:

  • Convert the fisheye image into a flat, natural-looking view.
  • Allow digital PTZ (pan, tilt, zoom) on the image for better viewing.
  • Improve usability in panoramic surveillance cameras and systems.
