ABSTRACT:
An omnidirectional visual sensor which can observe a 360-degree panoramic field area, obtain a sharp image and correctly transform a central projection with respect to the image and can be minimized as a whole includes a convex mirror with a surface of revolution having a focal point, a plurality of mirrors with surfaces of revolutions having at least one focal point, a photoreceiving lens system receiving light reflected by the convex mirror with the surface of revolution and the plurality of mirrors with surfaces of revolutions and an image acquisition surface receiving the light received in the photoreceiving lens system and converting the same to an electric signal, and the convex mirror with the surface of revolution and the plurality of mirrors with surfaces of revolutions are so arranged that the focal point of a first mirror included in the convex mirror with the surface of revolution and the plurality of mirrors with surfaces of revolutions aligns with the focal point of a second mirror, included in the convex mirror with the surface of revolution and the plurality of mirrors with surfaces of revolutions, further reflecting light reflected by the first mirror.
