Description

[0027] The above-mentioned properties, features and advantages of the invention and the way in which they are achieved will be explained more extensively by the following description of the exemplary embodiments of the invention in conjunction with the corresponding figures, in which:

[0028] FIG. 1 shows a schematic illustration of a rail vehicle with a video monitoring system,

[0029] FIG. 2 shows a flow diagram for a method for operating the video monitoring system for object monitoring.

[0030] FIG. 1 shows, in a schematic side view, a rail vehicle 1 with a video monitoring system 10 comprising two video cameras 3. The video monitoring system 10 is assigned to a vehicle interior 8 of a vehicle body 2 of the rail vehicle 1 and enables observation of the vehicle interior 8 and monitoring of luggage situated therein. For example, a plurality of luggage racks 4 are provided in the vehicle interior 8 and enable pieces of luggage 7 to be stowed. The video cameras 3 and the luggage racks 7 are usually oriented such that the luggage racks 7 are arranged in the field of view of the video cameras 3 or the recording region of the video cameras 3 encompasses one or more luggage racks 7.

[0031] The video monitoring system 10 is realized as a CCTV monitoring system, for example, which represents a self-contained video monitoring installation. A control unit 6 is coupled to the video cameras 3 in terms of signaling technology and is configured to operate the video monitoring system 10. Furthermore, the control unit 6 is coupled to a communication unit 5, which enables the video monitoring system 10 to communicate wirelessly with a mobile terminal 9 in terms of signaling technology.

[0032] As explained below, a method enables reliable and personalized luggage monitoring in the vehicle interior 8 of the rail vehicle 1 by means of the video monitoring system 10. Such a method for object monitoring can be carried out in accordance with the flow diagram shown in FIG. 2. A step S1 involves capturing measurement signals of a video camera 3 that are representative of image data of an environment of the vehicle interior 8 of the rail vehicle 1 within which a luggage rack 4 is also arranged.

[0033] A step S2 involves determining image data of the environment of the vehicle interior 8 depending on the captured measurement signal and identifying a piece of luggage 7 in the vehicle interior 8 depending on the determined image data. The identified piece of luggage 7 is provided for personalization.

[0034] Personalizing the piece of luggage 7 is effected in a further step S3 by for example a passenger in the rail vehicle 1 selecting the identified piece of luggage 7 by means of a mobile terminal 9. The mobile terminal is embodied in particular as a smartphone 9. The piece of luggage 7 to be monitored is thus assigned to and associated with the smartphone of a passenger.

[0035] In a further step S4, the fact of whether or not a manipulation of the identified piece of luggage 7 is present is determined on the basis of further image data of the video camera 3 and depending on a predefined manipulation condition. If a manipulation is recognized, then a notification signal is sent depending on the determined manipulation and depending on the personalizing of the identified piece of luggage 7. The notification signal is issued for example as acoustic sound, as visual indication on the display and/or as vibration of the smartphone of the passenger.

[0036] The method described enables personalized monitoring of luggage racks 4 by means of the video monitoring system 10 of the rail vehicle 1. An algorithm enables automatic recognition of pieces of luggage 7. A passenger can dial into the video monitoring system 10 for example wirelessly by means of his/her smartphone and follow a video recording of the video monitoring system. A preliminary selection of detected pieces of luggage 7 can be displayed on the display of the smartphone and the passenger can select the piece of luggage 7 to be monitored.

[0037] The video monitoring system 10 of the rail vehicle 1 is thus utilized for monitoring the selected piece of luggage 7 with regard to a possible manipulation. Such a manipulation can comprise concealment, movement, resorting, rotation and/or opening of the piece of luggage and can be determined by comparing with a corresponding manipulation condition. For example, a spatial threshold value is predefined which allows a tolerable movement of the piece of luggage 7. In the event of the spatial threshold value being exceeded, a manipulation is determined and the associated passenger is made aware of that by a notification signal.

[0038] The passenger can thereupon log into the video monitoring system 10 and check the current video recording with the luggage rack 4 situated therein. The passenger can thus check what triggered the notification and what is happening with his/her piece of luggage 7.

[0039] The method described thus enables reliable, convenient and automated monitoring of a respective piece of luggage 7 and personalized alerting of the passenger associated with the piece of luggage 7.

[0040] Although the invention has been illustrated and described in detail on the basis of exemplary embodiments, the invention is not restricted to the exemplary embodiments disclosed and the concrete feature combinations explained therein. Further variations of the invention can be obtained by a person skilled in the art, without departing from the scope of protection of the claimed invention.
