Sample 360-degree video in 360x180 equirectangular format. 360-degree videos, also known as surround video, [1] or immersive videos [2] or spherical videos, [3] are video recordings where a view in every direction is recorded at the same time, shot using an omnidirectional camera or a collection of cameras.
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.
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.
The diagram shows the mirror system and the synchronized engine that displays light from the high speed video projector. Spinning mirror systems are used to build interactive 3D graphics and autostereoscopic visuals visible to multiple simultaneous viewers, since a different view can be perceived by each viewer depending on the angle of vision.
It can also be used in 35-mm photography if it is large enough to allow the entire field of view to reach the camera. [2] In the case of a CCD camera, the flip mirror system works to let the viewer see exactly what the camera will see. [2] In this setup, the flip mirror is used as an accessory that helps to aim and focus.
