The location of objects in a building is recorded in the inventory management system. The objects are moved through the building with a vehicle. The vehicle transmits wireless messages indicating actions of the vehicle, such as loading or unloading of objects. A camera captures images of an area in which the vehicle moves. Positions of the vehicle are automatically detected from the captured images. The information about locations of objects is updated using the detected positions at time points indicated by the messages. In an embodiment the actions of the vehicle are signalled with light signals and picked up via the camera.
