Abstract

A camera system is configured to capture 360 degree image information of a local area, at least a portion of which is in stereo. The camera system includes a plurality of peripheral cameras, a plurality of axis cameras, a first rigid plate, and a second rigid plate, each aligned along an alignment axis. The peripheral cameras are arranged in a ring configuration that allows objects in the local area past a threshold distance to be within the fields of view of at least two peripheral cameras. The first and second rigid plates secure to a top and a bottom surface of the ring of peripheral cameras, respectively. At least one axis camera is arranged along the alignment axis and is coupled perpendicularly to a surface of the first rigid plate.
