A whole room or scene in one image

A fisheye lens covers a field of view close to or beyond 180 degrees by accepting strong barrel distortion: straight lines bend, and the scale changes from the centre to the edge. It is chosen for overview, monitoring and wide-area guidance, where coverage matters more than a uniform scale.

  • Compare the image circle with the sensor. A smaller circle gives a round image with dark corners; a larger one fills the frame with a narrower field.
  • Check the mount and the back focal distance against the camera or lens holder, and whether an infrared cut filter is involved.
  • Plan for the distortion: measurements need a calibration made for fisheye geometry, and resolution per degree is lowest at the edge.
