A floor or a roof for guiding an automated self-propelled vehicle has a position-coding pattern (30) which is designed in such manner that an arbitrary subset of the position-coding pattern, which subset has a predetermined size, codes the absolute coordinates for a position within at least a partial area of the floor (3) or roof, so that the absolute position of an automated self-propelled vehicle can be determined within this partial area by recording an image of the floor which comprises at least said subset. An automated self-propelled vehicle intended to navigate on the floor comprises a control means for controlling the movement of the vehicle and an image sensor connected to the control means for recording an image of a floor or a roof. The control means is adapted, in response to the image comprising a position-coding pattern, to convert the position-coding pattern (30) to a position, and to control the movement of the vehicle in response to the position. |
