Abstract

A method for controlling a paint mixing device and/or a paint application device, a mobile digital terminal capturing a scene, in particular a project, via an interface for augmented reality, and a virtual coloring and/or material illustration being superimposed on the scene, wherein the virtual coloring is classified according to one or more technical or pre-specified color spaces, and a control statement for a paint mixing device and/or a paint application device is determined from the classification.

First claim

The invention claimed is:

1 . A method for controlling a paint mixing device, the method comprising:
capturing, with a mobile digital terminal, an image of a scene, the scene including a project object, superimposing, via an interface for augmented reality on the mobile digital terminal, a virtual coloring and/or material illustration of the project object on the image of the scene, classifying the virtual coloring and/or material illustration of the project object according to one or more technical or pre-specified color spaces, and generating a control statement for a paint mixing device to produce a mixed paint based on the classification.

2 . The method as claimed in claim 1 , wherein the control statement comprises data corresponding to the project object included in the image of the scene, and wherein the data is recorded or generated by the mobile terminal.

3 . The method as claimed in claim 2 , wherein the mobile digital terminal receives secondary data via a data interface, the secondary data comprising existing colorings and/or existing color spaces and/or stored templates.

4 . The method as claimed in claim 1 , wherein the control statement comprises a mixing process control statement configured to control the paint mixing device based on a composition of color components of the project object.

5 . The method as claimed in claim 1 , wherein the control statement comprises a spraying process control statement configured to control a paint application device to perform a spraying process for producing a specific material illustration, wherein the specific material illustration comprises at least one of a surface appearance, a surface structure, or a surface coating.

6 . The method as claimed in claim 5 , wherein the control statement comprises a project identification and/or object identification, and the control statement comprises a functional approval for the paint application device to perform the spraying process based on the project identification and/or the object identification.

7 . The method as claimed in claim 1 , and further comprising a paint application device, wherein the control statement further comprises a spraying control statement configured to control the paint application device to apply the mixed paint on a surface.

8 . The method as claimed in claim 1 , wherein the paint mixing device comprises:
a plurality of storage containers, the storage containers each being filled with a paint of a base color, and a mixing unit, wherein one or more paints are removed from the plurality of storage containers and are mixed in the mixing unit to form the mixed paint, wherein the mixed paint includes a pre-specified color in a pre-specified amount of paint.

9 . A paint spraying device comprising:
a mobile digital terminal including a camera configured to capture an image of a scene including a project object; an augmented reality interface displayed on the mobile digital terminal, wherein the augmented reality interface is configured to display a material illustration of the project object on the image of the scene; a classification module configured to classify the material illustration of the project object according to one or more technical or pre-specified color spaces; a paint mixing device configured to produce a mixed paint having a color based on the classification; and a spraying unit comprising at least one paint container for storing paint to be sprayed, wherein the at least one paint container is filled with the mixed paint having the color based on the classification.

10 . The paint spraying device as claimed in claim 9 , wherein the at least one paint container is formed as a single-use container.

11 . The paint spraying device as claimed in claim 9 , wherein the at least one paint container is formed as a single-use cartridge, the cartridge comprising at least one paint line and an atomizer nozzle.

12 . The paint spraying device as claimed in claim 9 , wherein the at least one paint container is formed as a multi-use container.

13 . The paint spraying device as claimed in claim 9 , wherein the at least one paint container is formed as a multi-use cartridge comprising at least one paint line and an atomizer nozzle.

14 . The paint spraying device as claimed in claim 9 , wherein the spraying unit comprises a project identification and/or object identification, and wherein a control statement for the spraying unit comprises a functional approval for the spraying unit to perform a spraying operation based on the project identification and/or the object identification.

15 . The paint spraying device as claimed in claim 9 , and further comprising a control statement configured to control the spraying unit to perform a a spraying operation, wherein the spraying operation includes applying the mixed paint on a surface, and wherein the spraying operation further includes controlling at least one of: spraying volume, spraying pulses, spraying pressure, or physical spraying parameters.

16 . The paint spraying device as claimed in claim 9 , wherein the spraying unit is a hand-held spraying unit.

17 . The paint spraying device as claimed in claim 9 , wherein the paint spraying device comprises a mobile energy source.

18 . The paint spraying device as claimed in claim 9 , wherein the paint spraying device operates on the basis of an HVLP process for paint application.

19 . A paint spraying device comprising:
a mobile digital terminal including a camera configured to capture an image of a project object; an interface generated by the mobile digital terminal, the interface configured to generate a material illustration of the project object; a classification module configured to classify the material illustration according to one or more technical or pre-specified color spaces; a control unit configured to determine, from the classification, a project identification tag corresponding to the material illustration of the project object, a paint container comprising a container identification tag, wherein the container identification tag is associated with the project identification tag, and wherein the container identification tag is configured to be used to assign a control statement for a paint mixing device to the paint container.

20 . The paint spraying device as claimed in claim 19 , wherein the one or more technical or pre-specified color spaces comprise:
at least one of PANTONE or RAL.
