Abstract:
1. A surround surveillance system mounted on a mobile body for surveying surroundings around the mobile body, comprising an omniazimuth visual system, the omniazimuth visual system including: at least one omniazimuth visual sensor including an optical system capable of obtaining an image with an omniazimuth view field area therearound and capable of central projection transformation of the image into an optical image, and an imaging section including an imaging lens for converting the optical image obtained by the optical system into image data; an image processor for transforming the image data into at least one of panoramic image data and perspective image data; a display section for displaying one of a panoramic image corresponding to the panoramic image data and a perspective image which is panned or tilted corresponding to the perspective image data; and a display control section for controlling the display section; wherein the optical system includes a hyperboloidal mirror which has a shape of one sheet of a two-sheeted hyperboloid, an optical axis of the hyperboloidal mirror being identical with an optical axis of the imaging lens, and the principal point of the imaging lens being located at one of focal points of the hyperboloidal mirror, and wherein the at least one omniazimuth visual sensor is stationary with respect to the mobile body, such that the perspective image, which is panned or tilted corresponding to the perspective image data, is obtained by transforming the image data obtained from the optical image taken by the at least one omniazimuth visual sensor.
