camera type

Omnidirectional camera

In photography, an omnidirectional camera (from "omni", meaning all) is a camera with a 360-degree field of view in the horizontal plane, or with a visual field that covers (approximately) the entire sphere. Omnidirectional cameras are important in areas where large visual field coverage is needed, such as in panoramic photography and robotics.

Fisheye lens

 A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic orhemispherical image.^[1][2] Fisheye lenses achieve extremely wide angles of view by forgoing producing images with straight lines of perspective (rectilinear images), opting instead for a special mapping (for example: equisolid angle), which gives images a characteristic convex non-rectilinear appearance.
