Abstract

In particular, a method performed by one or more devices is disclosed, the method comprising: obtaining an intensity information item representative of a spectral image resulting from a soiling of a textile and/or from at least one part of a textile; determining at least one output variable dependent on the soiling of the textile and/or at least one property of the textile from the intensity information item, wherein the output variable is determined by employing an adaptive evaluation algorithm, in particular an artificial neural network, wherein parameters of the adaptive evaluation algorithm are calibrated based on a plurality of training cases; outputting or triggering outputting of the at least one output variable. Furthermore, a device and a system for performing the subject method is disclosed.

First claim

obtaining an intensity information item of a spectral image resulting from soiling of a textile and/or for at least one part of a textile; determining at least one output variable from the intensity information item dependent on the soiling of the textile and/or on at least one property of the textile, wherein the output variable is determined by employing an adaptive evaluation algorithm, wherein parameters of the adaptive evaluation algorithm are calibrated based on a plurality of training cases; outputting or triggering an outputting of the at least one treatment variable.

2 . The method according to claim 1 , wherein obtaining the intensity information item comprises the following steps:
(i) illuminating the soiling of the textile and/or the at least one part of textile with light comprising at least one broadband wavelength range; (ii) detecting an image information item of the illuminated soiling of the textile and/or the illuminated at least one part of the textile; (iii) determining at least a reflection information item indicative of the reflected light from the wavelength channels of the image information items corresponding to the at least one broadband wavelength; (iv) reconstructing a spectral image, wherein an evaluation of the at least one reflection information item takes place.

3 . The method according to claim 2 , wherein illuminating the soiling of the textile and/or the at least one part of textile is done with one of the following broadband wavelength ranges:
(i) from about 600 nm to about 780 nm; (ii) from about 490 nm to about 600 nm; (iii) from about 380 nm to about 490 nm; (iv) or a combination thereof.

4 . The method according to claim 1 , wherein at least one image point within the spectral image is used as a fixed predetermined reference image point for a spectral exposure compensation of the image, wherein image data of image points of the image which are different from the at least one reference image point are normalized using image data of the at least one reference image point.

5 . The method according to claim 1 , wherein the at least one part of the textile is indicative of material structure, material type, material distribution, material wear of the textile or a combination thereof.

6 . The method according to claim 1 , the method further comprising:
determining at least one treatment parameter of the textile based at least in part on the intensity information item; and outputting or triggering an outputting of the at least one treatment parameter.

7 . The method according to claim 1 , wherein the at least one treatment parameter is indicative of a cleaning agent type, an amount of cleaning agent, a cleaning temperature, a type of cleaning device, settings of a cleaning device, or a combination thereof.

8 . The method according to claim 1 , the method further comprising:
performing or causing the performance of a treatment of the textile corresponding to the at least one determined treatment parameter via at least one treatment device.

9 . The method according to claim 1 , wherein the intensity information item is determined before, during and/or after a treatment of the textile.

10 . The method according to claim 1 , wherein at least one optical sensor element is used to determine the intensity information item.

11 . The method according to claim 10 , wherein the optical sensor element provides three-dimensional spatial resolution.

12 . The method according to claim 10 , wherein the at least one optical sensor element comprises at least one camera-like element and provides an image information item of the soiling of the textile and/or the at least one part of a textile.

13 . A device which is configured as or comprises corresponding elements to perform and/or to control a method according to claim 1 .

14 . A computer program comprising program instructions that cause a processor to execute and/or control a method according to claim 1 when the computer program is run on the processor.

15 . (canceled)

16 . The method according to claim 2 , wherein at least one image point within the spectral image is used as a fixed predetermined reference image point for a spectral exposure compensation of the image, wherein image data of image points of the image which are different from the at least one reference image point are normalized using image data of the at least one reference image point.

17 . The method according to claim 3 , wherein at least one image point within the spectral image is used as a fixed predetermined reference image point for a spectral exposure compensation of the image, wherein image data of image points of the image which are different from the at least one reference image point are normalized using image data of the at least one reference image point.

18 . The method according to claim 2 , the method further comprising:
determining at least one treatment parameter of the textile based at least in part on the intensity information item; and outputting or triggering an outputting of the at least one treatment parameter.

19 . The method according to claim 3 , the method further comprising:
determining at least one treatment parameter of the textile based at least in part on the intensity information item; and outputting or triggering an outputting of the at least one treatment parameter.

20 . The method according to claim 17 , the method further comprising:
