Abstract

The invention relates to a portable device (1100) comprising a bottom surface (BS) intended to be in contact with a textile (TXT). The portable device comprises an image sensor (5) for taking an image of a textile, and an illumination system (6) for illuminating a portion of the textile when said image is being taken. The portable device also comprises a control unit (8a) for executing an algorithm stored in the portable device, using the taken image as an input of said algorithm, to obtain a classification of the textile. The image sensor and the control unit are integrated within the portable device. The image sensor has an active surface sensitive to light, which is oriented compared to said bottom surface (BS), with an absolute value of the orientation angle being in the range 15-70 degrees; and/or the illumination system (6) has a light source oriented compared to the said bottom surface (BS), with an absolute value of the orientation angle being in the range 15-70 degrees.

First claim

The invention claimed is:

1. A portable device comprising a bottom surface intended to be in contact with a textile, the portable device comprising:
an image sensor for taking an image of a textile;
an illumination system for illuminating a portion of the textile when said image is being taken;
a control unit for executing an algorithm stored in the portable device, using the taken image as an input of said algorithm, to obtain a classification of the textile; wherein:
the image sensor and the control unit are integrated within the portable device;
the image sensor has an active surface sensitive to light, which is oriented compared to said bottom surface, with an absolute value of the orientation angle being in the range 15-70 degrees; and/or
the illumination system has a light source oriented compared to the said bottom surface, with an absolute value of the orientation angle being in the range 15-70 degrees.

2. The portable device according to claim 1 , wherein the algorithm includes an artificial neural network, preferably a convolutional neural network having at least one convolutional layer.

3. The portable device according to claim 1 , further comprising a first communication module for connecting the portable device to an external computing system.

4. The portable device according to claim 3 , further comprising an interface for receiving a user input of a user using the portable device, wherein said user input corresponds to a different classification of the textile derived from the classification of the textile obtained by the control unit on the basis of the taken image,
wherein the first communication module is adapted to transmit to the external computing system said different classification and the taken image, and
wherein the first communication module is further adapted to receive, from the external computing system, an updated version of said algorithm.

5. The portable device according to claim 4 , wherein the portable device is further adapted to store a plurality of said different classification and associated taken image, before transmission to said external computing system.

6. The portable device according to claim 1 , further comprising a second communication module for connecting the portable device to a domestic appliance, said second communication system being adapted to transmit said classification, or an information reflecting said classification, to the domestic appliance for use in controlling, based on said classification, at least one operating parameter of the domestic appliance.

7. The portable device according to claim 6 , wherein the second communication module is adapted for a wired connection or a wireless connection with the domestic appliance.

8. The portable device according to claim 1 , further comprising a display for displaying said classification.

9. The portable device according to claim 1 , wherein said classification is chosen among:
a fabric type of the textile,
information relating to a level of delicateness of the fabric.

10. The portable device according to claim 1 , wherein a field of view of the image is in the range 1 mm 2 to 25 mm 2 .

11. The portable device according to claim 1 , corresponding to a portable textile classifier device, a mobile phone or a smartphone.

12. A domestic appliance comprising:
a third communication module for connecting with a portable device according to claim 1 , the third communication module being adapted to receive said classification or an information reflecting said classification, from the portable device, and
a control unit for controlling, based on said classification, at least one operating parameter of the domestic appliance.

13. The domestic appliance according to claim 12 , corresponding to a textile treatment device.

14. The domestic appliance according to claim 13 , wherein the textile treatment device is taken among a set defined by a pressurized steam ironing system with a boiler, a pressurized steam ironing system without the boiler, a steam ironing device, a handheld garment steamer, a stand garment steamer, a stain removal device, a washing machine device, and a dry ironing device.

15. The domestic appliance according to claim 12 , wherein said at least one operating parameter corresponds to a temperature for treating the textile and/or an amount of steam applied to the textile for treating the textile.
