Some omnidirectional cameras contain wide-angle lenses on the front and rear to facilitate the recording of 360-degree video. 360-degree video is typically recorded using either a special rig of multiple cameras, or using a dedicated camera that contains multiple camera lenses embedded into the device, and recording overlapping angles simultaneously.
Schematic of an omnidirectional camera with two mirrors: 1. Camera 2. Upper Mirror 3. Lower Mirror 4. "Black Spot" 5. Field of View (light blue) In photography, an omnidirectional camera (from "omni", meaning all), also known as 360-degree camera, is a camera having a field of view that covers approximately the entire sphere or at least a full circle in the horizontal plane.
Omnidirectional (360-degree cameras) can capture spherical 360° 180° panoramic photos or videos. This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources .
It is used to encode and deliver the effect of a spherical, 360-degree image to viewers such as needed for 360-degree videos and for virtual reality. A 360 video projection is a specialized form of a map projection , with characteristics tuned for the efficient representation, transmission, and display of 360° fields of view.
A ball camera or camera ball is a spherical camera, one version of which has been designed to be thrown into the air to take panoramic pictures from a height or in an inaccessible or dangerous location. Several models of "throwable ball cameras" have been developed in the 2010s.
The camera was an Olympus or Nikon CoolPix camera and the lenses used were the Nikon FC-E8 or FC-E9 fish-eye lens. The IPiX 360 camera system enabled photographers to capture a full 360 X 360 floor to ceiling view of any scene with just 4 shots as opposed to the more time-consuming 8, 10, or 12-shot rectilinear produced panoramas described above.
Spherical mirrors, however, suffer from spherical aberration—parallel rays reflected from such mirrors do not focus to a single point. For parallel rays, such as those coming from a very distant object, a parabolic reflector can do a better job. Such a mirror can focus incoming parallel rays to a much smaller spot than a spherical mirror can.
In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
