The beverage preparation machine further includes a control unit configured to determine a receptacle volume based on the first and second images and to determine a beverage volume
A beverage preparation machine includes first and second cameras for capturing first and second images of a receptacle. The beverage preparation machine further includes a control unit configured to determine a receptacle volume based on the first and second images and to determine a beverage volume to be dispensed based on the receptacle volume and the selected filling level or percentage. Regardless of the shape, volume, and/or material of the receptacle, the filling level or percentage for dispensing the beverage can be freely selected via a user interface.

1. A beverage preparation machine, comprising: a beverage outlet for dispensing a beverage into a receptacle;a first camera for capturing a first image of the receptacle, wherein the first camera is provided with anti-condensation means;a second camera for capturing a second image of the receptacle;
1. A beverage preparation machine, comprising: a beverage outlet for dispensing a beverage into a receptacle;a first camera for capturing a first image of the receptacle, wherein the first camera is provided with anti-condensation means;a second camera for capturing a second image of the receptacle;a user interface for selecting a filling level or percentage of the receptacle; anda control unit configured to determine a receptacle volume based on the first image and the second image, and to determine a beverage volume to be dispensed based on the receptacle volume and the selected filling level or percentage. 2. The beverage preparation machine according to claim 1, wherein the first camera is positioned for capturing a top-view image of the receptacle as the first image, and the second camera is positioned for capturing a side-view image of the receptacle as the second image. 3. The beverage preparation machine according to claim 1, wherein the first camera is positioned at the beverage outlet, and the second camera is positioned between the beverage outlet and a support for receiving the receptacle. 4. The beverage preparation machine according to claim 1, wherein the control unit is configured to calculate: from the first image: the area of the rim, the inner diameter, outer diameter of the rim of the receptacle, the area of the inner bottom, the inner diameter of the bottom of the receptacle, and a wall thickness of the receptacle and,from the second image: the outer shape of the receptacle, the outer height of the receptacle, the width or outer diameter of the outer bottom of the receptacle. 5. The beverage preparation machine according to claim 4, wherein control unit is configured to further calculate from the second image the largest width and a width increase, if any, of the receptacle at a distance of the top and bottom of the receptacle. 6. The beverage preparation machine according to claim 1, wherein the control unit is configured to calculate from the first and second image an uneven wall thickness of the receptacle. 7. The beverage preparation machine according to claim 1, wherein the control unit is configured to display based on the second image an image of the receptacle on the user interface. 8. The beverage preparation machine according to claim 1, wherein the user interface comprises a touch-screen or touch-pad. 9. The beverage preparation machine according to claim 1, wherein the control unit is configured to determine a water volume in a water tank of the machine and to issue a feedback signal when the water volume is less than the beverage volume to be dispensed. 10. The beverage preparation machine according to claim 9, wherein the control unit is configured to issue a warning signal when the water volume is less than the determined receptacle volume. 11. The beverage preparation machine according to claim 1, further comprising a memory unit for storing a database including pre-stored images of receptacles, wherein the control unit is configured to determine whether the receptacle is included in the database by matching the first image and/or the second image with the pre-stored images of receptacles, and to read a correspondingly stored receptacle volume if the receptacle is included in the database. 12. The beverage preparation machine according to claim 11, wherein the control unit is configured to update the database by storing a new image of the receptacle based on the first image and/or the second image. 13. The beverage preparation machine according to claim 11, wherein the control unit is configured to record a beverage consumption for each of the receptacles in the database, and to display on the user interface information regarding the beverage consumption of a currently used receptacle. 14. The beverage preparation machine according to claim 1, wherein the first camera and the second camera are configured to capture images at predetermined time intervals, and the control unit is configured to activate the beverage preparation machine from a stand-by mode, when the first and second image of the receptacle, respectively, are captured for a predetermined number of consecutive time intervals. 15. A beverage preparation machine, comprising: a beverage outlet for dispensing a beverage into a receptacle;a first camera for capturing a first image of the receptacle;a second camera for capturing a second image of the receptacle;a user interface for selecting a filling level or percentage of the receptacle;a control unit configured to determine a receptacle volume based on the first image and the second image, and to determine a beverage volume to be dispensed based on the receptacle volume and the selected filling level or percentage; anda memory unit for storing a database including pre-stored images of receptacles, wherein the control unit is configured to determine whether the receptacle is included in the database by matching the first image and/or the second image with the pre-stored images of receptacles, and to read a correspondingly stored receptacle volume if the receptacle is included in the database. 16. The beverage preparation machine according to claim 15, wherein the control unit is configured to update the database by storing a new image of the receptacle based on the first image and/or the second image. 17. The beverage preparation machine according to claim 15, wherein the control unit is configured to record a beverage consumption for each of the receptacles in the database, and to display on the user interface information regarding the beverage consumption of a currently used receptacle.
