WebFish-eye lenses allow imaging a large sector of the surrounding space with omni-directional vision. This justifies its use. According to [1] we can view the classical problem of stereo analysis as consisting of the following steps: image acquisition, camera modelling, feature acquisition, im- age matching, depth determination and interpolation. WebThe evolution of terrestrial vision has been linked to a common fish ancestor. Not surprisingly, the basic anatomical structures of the eye are similar to that of humans. Many fish possess rods and cones embedded in the retina that receives light as it passes through the cornea and the lens as well as a cone-dense fovea.
