Abstract

An arrangement for obtaining body measurements of a person includes a garment configured to be form fitted to the person, a reference target, and a handheld digital camera. A surface of the garment includes a plurality of first fiducials which are photogrammetrically analyzable. The reference target includes a plurality of second fiducials that are photogrammetrically analyzable. The plurality of second fiducials on the reference target facilitate producing a 3D model true to scale and in a recognized orientation to a surface on which the person is standing. The handheld digital camera acquires a plurality of successive images of the garment and reference target as the digital camera is moved around the person. A computer processes the plurality images by methods of photogrammetry to produce a 3D model of the body. A portable stabilization device may be held by the person to reduce movement and control arm spacing during image acquisition.

Dependent claims

A method of obtaining body measurements of a person, the method comprising:

enclosing a portion of a body of the person in a form fitting garment, wherein a surface of the form fitting garment includes a plurality of first fiducials that are photogrammetrically analyzable, wherein the portion of the body includes one or more limbs of the body and/or a torso of the body;
having the person stand near a reference target, wherein the reference target includes a plurality of reference markers that are recognizable by image processing software, and a plurality of second fiducials that are photogrammetrically analyzable;
moving a digital camera around the person and acquiring a plurality of images of the at least one garment and reference target, wherein at least one image is acquired at successive positions of the digital camera as it is moved around the person;
and
processing the plurality images by one or more photogrammetry methods to produce a 3D model of the portion of the body.

An arrangement for obtaining body measurements of a body of a person, the arrangement comprising:

a garment configured to be form fitted to the body, wherein a surface of the garment comprises a plurality of first fiducials which are photogrammetrically analyzable, wherein the surface of the garment has a first color and wherein the plurality of first fiducials have a second color different from the first color;
a reference target to be positioned near the person, wherein the reference target comprises a plurality of reference markers that are recognizable by image processing software, and a plurality of second fiducials that are photogrammetrically analyzable, wherein the plurality of second fiducials on the reference target are of known proportion and facilitate producing a 3D model of the body true to scale and in a recognized orientation to a surface on which the person is standing;
and
a handheld device comprising a digital camera, wherein the digital camera is configured to acquire a plurality of successive images of the garment and reference target as the device is moved around the person, wherein a processor associated with the handheld device is configured to remove background from the plurality of images by removing portions of the images not having the first and second colors.
