## 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

### Claim 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, wherein said image capturing means is positioned behind said wavelength specific mirror, wherein said wavelength specific mirror transmits at least 70% of infrared light with wavelengths of at least 750 nm and reflects at least 85% of visible light wavelengths from 380 nm to 740 nm, wherein said projector is positioned behind said wavelength specific mirror, and wherein the projector projects structured infrared light through said wavelength specific mirror and onto the three-dimensional object to be measured such that the structured infrared light waves are reflected off the three-dimensional object to be measured and captured by said image capturing means that is positioned behind the wavelength specific mirror, the structured infrared light consisting of wavelengths in a range outside of the visual spectrum, and wherein the capturing means consists of one or more structured light camera having a frame rate of at least 10 frames per second.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 3)

The three-dimensional measuring device according to claim 3, wherein said image capturing means are oriented along the same vertical axis.

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 5)

The three-dimensional measuring device according to claim 5, wherein said two or more projectors are positioned behind the wavelength specific mirror.

### Claim 7 (depends on 6)

The three-dimensional measuring device according to claim 6, wherein said two or more projectors are oriented along the same vertical axis.

### Claim 8 (depends on 1)

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 claim 1;
projecting from a projector positioned behind the wavelength specific mirror structured near infrared light consisting of wavelengths in a range outside of the visual spectrum through said wavelength specific mirror on said object;
capturing images from the structured near infrared light waves projected on the object using image capturing means positioned behind said wavelength specific mirror;
transmitting said captured images from said image capturing device to a computer processor and having said computer processor process said image to determine the three-dimensional shape of said object.

### Claim 9 (depends on 8)

The method according to claim 8, further including rotating the object or causing said object to rotate in front of the wavelength specific mirror.

### Claim 10 (depends on 8)

The method according to claim 8, wherein the images are captured at a frame rate of at least 10 frames per second.
