Abstract:
Provided is a compact stereo camera capable of performing high-accuracy and wide-angle sensing. The stereo camera includes a first mirror having a first reflective surface, a first vertex, and a first fan shape, and a second mirror having a second reflective surface, a second vertex facing the first vertex, and a second fan shape. The imaging optical system forms an image of first light emitted from a subject, reflected on the first reflective surface, and then further reflected on the second reflective surface, and second light emitted from the subject and reflected on the second reflective surface. The image sensor receives the first light and the second light via an imaging optical system. The second mirror includes an outer mirror and an inner mirror located on an inner peripheral side of the outer mirror and having a conic constant different from that of the outer mirror. The image sensor is disposed at a position where a center position thereof is shifted from an optical axis of the imaging optical system.
