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