Abstract

An imaging technique, suitable for surveillance use by a moving robotic vehicle carrying two spatially displaced fixed cameras aligned with the direction of travel or, alternatively, a single camera movable to either of two positions on the vehicle corresponding to the positions occupied by the fixed cameras, is capable in a moving object indicator mode of deriving first image data of a viewed scene at a first time from a first position with respect to the vehicle and of deriving second image data of the viewed scene at a second time from a second position with respect to the vehicle that is spatially displaced a given distance from the first position such that the spatial position with respect to the viewed scene depicted by the second image data at least approximates the spatial position with respect to the viewed scene depicted by the first image data. As an aid to detecting driving hazards encountered by the moving vehicle, the imaging technique may also be operated in a stereo-vision mode, in which the first and second image data is derived at the same time from the same angle of gaze of the viewed scene.
