Abstract

The present invention relates to a fitting room mirror including image capturing means and image processing means enabling the determination of body dimensions and in providing cloth-fitting advice to the user.

Claims

1. A three-dimensional measuring device for use in a garment fitting room comprising at least one image capturing means, a projector, and a wavelength specific mirror characterized in that said image capturing means is position behind said wavelength specific mirror, and characterized in that said wavelength specific mirror transmits at least 70% of infrared light with wavelengths of at least 750 nm.

2. The three-dimensional measuring device according to claim 1, wherein said wavelength specific mirror reflects all the visible light wavelengths.

3. The three-dimensional measuring device according to claim 1, wherein said wavelength specific mirror reflects visible light wavelengths from about 380 nm to about 740 nm for at least 70%.

4. The three-dimensional measuring device according to claim 1, wherein the projector projects structured infrared light on the three-dimensional object to be measured.

5. The three-dimensional measuring device according to claim 1, wherein the capturing means consists of structured light camera(s) capturing images at a frame rate of at least 10 frames per second.

6. The three-dimensional measuring device according to claim 1, further comprising display means positioned behind said wavelength specific mirror.

7. The three-dimensional measuring device according to claim 1, comprising two or more image capturing means.

8. The three-dimensional measuring device according to claim 7, wherein said image capturing means are oriented along the same vertical axis.

9. The three-dimensional measuring device according to claim 1, comprising two or more projectors.

10. The three-dimensional measuring device according to claim 1 or 9, wherein said projector(s) are positioned behind the wavelength specific mirror.

11. The three-dimensional measuring device according to claim 10, wherein said two or more projectors are oriented along the same vertical axis.

12. Use of the three-dimensional measuring device according to any one of claims 1 to 11, as a mirror.

13. A method for the acquisition of three-dimensional shapes of an object, said method comprising;

placing the three dimensional object to be measured in front of a wavelength specific mirror as defined in any one of claims 1 to 11;

projecting structured near infrared light on said object from a projector;

capturing images from the structured near infrared light waves projected on the object using image capturing means positioned behind said wavelength specific mirror;

transmit said captured images from said image capturing device to a computer processor and have said computer processor process said image to determine the three-dimensional shape of said object.

14. The method according to claim 14, further including the step of rotating the object or causing said object to rotate in front of the wavelength specific mirror.

15. The method according to claim 14, wherein the images are captured at a frame rate of at least 10 frames per second.
