Whole Sky Camera – Wikipedia, The Free Encyclopedia
Whole sky camera – specialized camera used in meteorology and astronomy for photography of the whole sky. Whole sky camera typically uses a fisheye lens that takes in an extremely wide, hemispherical image. Such lens was originally developed for use in meteorology. However, alternative … Read Article
Fisheye lens Designs And Their Relative Performance James …
Fisheye lens designs have widely varying relative illumination and distortion across the hemispherical field of view of the lens. After describing the contributing factors to relative illumination, we survey a collection of fisheye designs and compare their illumination performance, radial mapping … Fetch Here

Hemispherical Photographs Used For Mapping Confined Spaces
A camera equipped with a hemispherical lens, or fisheye lens, may represent the best acquisition tool. With a 180-de- gree angular field, the fisheye lens has the capability to re- … Access Full Source
GEOMETRIC MODELLING AND CALIBRATION OF FISHEYE LENS CAMERA …
hemispherical images using radiation models and a sun path model. Hence, it is necessary to know the geometrical relation between image space and object space. This means that the fisheye lens camera system used has to be calibrated in order to … Access Full Source
GEOMETRIC MODELLING AND CALIBRATION OF FISHEYE LENS CAMERA …
This is realised by the types and the configuration of the lenses of a fisheye lens system. Figure 2b. Fisheye projection model 2.2 Fisheye projection model To reconstruct the projection of an object point into the hemispherical image, the object coordinates and image coordinates have to refer … Retrieve Doc
A Comparison Of Fisheye Lenses For Interactive Layout Tasks
We compared performance on layout tasks with three kinds of fisheye: a full-screen pyramid lens, a constrained hemispherical lens, and a constrained flat-topped hemisphere. … Access Document
Full-View Spherical Image Camera
Each hemispherical field of view is imaged by a fisheye lens, respectively. The both of hemispherical views are fused by a mirror so as to acquire them on a single image plane. … Get Document
Distortion (optics) – Wikipedia, The Free Encyclopedia
Fisheye lenses, which take hemispherical views, utilize this type of distortion as a way to map an infinitely wide object plane into a finite Corel Paint Shop Pro Photo include a manual Lens Distortion effect for simple (barrel, fisheye, fisheye spherical and pincushion) distortion. … Read Article

A Flexible Architecture For Fisheye Correction In Automotive …
There are two kinds of fisheye images: ■ Circular (hemispherical) fisheye images are formed when the entire hemispherical view is projected onto a circle within the A fisheye lens is characterized by two basic parameters: the focal length and the FOV. … Retrieve Full Source
Cata-Fisheye Camera For Panoramic Imaging
In this work, we present a novel panoramic imaging sys-temthatusesa curved mirror as a simple and compact at-tachmenttoa fisheye lens. We refer to this as a cata-fisheye system. Fisheye lenses usually havea hemispherical FOV. … View Doc
