WebJun 11, 2024 · Usually, the fish eye lens has a very short focal length (less than 15mm for a 35mm-size image sensor), but a large field of view (FOV). The latter can be as large as 180-degrees, giving the user a complete view of a scene. This extreme FOV produces a characteristic image with a large distortion. Figure 1: Fisheye image with large distortion. WebMar 24, 2024 · Fisheye cameras have larger FoV than ordinary pinhole cameras, yet its unique special imaging model naturally leads to a blind area at the edge of the image plane. This is suboptimal for safety-critical applications since important perception tasks, such as semantic segmentation, become very challenging within the blind zone.
