Abstract: There is provided an electrically-powered material-transport vehicle having a vehicle-charging contact on one side of the vehicle, and a second vehicle-charging contact on the opposite side of the vehicle. The vehicle has a load-bearing cap that covers the top of the vehicle, and a cap elevator for raising and lowering the cap. The cap can be raised and lowered to a transit position, a payload-engagement position, a charging position, and a maintenance position. In the transit position and payload-engagement position, the cap covers the vehicle-charging contacts so that they are not exposed. In the charging position, the cap is raised so that the vehicle-charging contacts are exposed. The vehicle can enter a charging-dock with the cap in the charging position in order to recharge the vehicle's battery.

Abstract: A method for segmenting a first scene from a sequence of scenes is described. In this case, the sequence of scenes was captured by a camera in or on a vehicle such as by smartglasses. The method determines an optical flow of the first scene, on the basis of the sequence of scenes. In addition, the method determines statistical variables of the optical flow in different partial regions of the first scene. Furthermore, the method determines, on the basis of the statistical variables, a separating line between a foreground region and a background region of the first scene. In this case, determining the separating line includes determining, on the basis of the statistical variables, an indicator of whether the optical flow in the background region is attributable to a movement of the vehicle.
