Abstract
An omnidirectional camera comprises a camera mounting frame of cylindrical hollow body, a plurality of horizontal camera units, each of which is provided on a horizontal plane orthogonal to a center line of the camera mounting frame and adapted to acquire an image in a horizontal direction. A vertical camera unit is provided so as to coincide with the center line of the camera mounting frame and adapted to acquire an image in a zenith direction. A ring-like GPS antenna is provided so as to surround the vertical camera unit.
Claims5
An omnidirectional camera comprising a camera mounting frame of cylindrical hollow body, a plurality of horizontal camera units adapted to acquire an image in a horizontal direction, a vertical camera unit adapted to acquire an image in a zenith direction, and a GPS antenna provided so as to surround said vertical camera unit, wherein said horizontal camera units are arranged so that optical axis of said horizontal camera units exist on a horizontal plane orthogonal to a center line of said camera mounting frame and coincide with one point of a reference point positioned on said center line of said camera mounting frame and said vertical camera unit is concentric with said GPS antenna, penetrates a central portion of said GPS antenna and is arranged so that an optical axis of said vertical camera unit coincides with said center line of said camera mounting frame and said reference point is set as a reference position of images acquired by all cameras of said horizontal camera units and said vertical camera unit, and wherein said GPS antenna is provided so that a phase center of said GPS antenna is positioned on said center line of said camera mounting frame.
