What is the difference between IMV1-1/3 and Generic Dewarp?
Description
When user would like to add a fisheye camera into NUUO products,
there are two types of lens setting -- IMV1-1/3 and Generic Dewarp,
what is the difference?

Solution
-
IMV1-1/3 is for "normal camera with an extra immervision lens", which is a way to make normal camera to become fisheye camera. Here is the Immervision website, and campatible camera list.
-
Generic Dewarp is for fisheye camera, the lens are already built inside the camera. In camera support list of Mainconsole, you will see a note below the camera model: fisheye camera, it means, this camera could use "Generic Dewarp"

-
Why we need Generic Dewarp for fisheye camera? Please check the below image:
As you can see the image at the left, it is the original image of fisheye camera, this one is hard to identify, since the panoramic view is captured in a circular picture. the other images at the right show the results after dewarp, they are easily to identify, and still have the advantage of the panoramic view.
