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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The method of claim 1, further comprising enclosing an additional portion of the body of the person with a second form fitting garment, wherein a surface of the second garment includes a plurality of the first fiducials. ### Claim 3 (depends on 1) The method of claim 1, further comprising enclosing an additional portion of the body of the person with an accessory, wherein a surface of the accessory includes a plurality of the first fiducials, and wherein the accessory comprises a hat, a head band, at least one glove, or at least one sock. ### Claim 4 (depends on 1) The method of claim 1, wherein the surface of the garment has a first color and the plurality of first fiducials have a second color different from the first color. ### Claim 5 (depends on 1) The method of claim 1, where the plurality of second fiducials on the reference target are of known proportion and facilitate producing the 3D model true to scale and in a recognized orientation to a surface on which the reference target is positioned. ### Claim 6 (depends on 1) The method of claim 1, further comprising removing background from the plurality of images prior to the processing step. ### Claim 7 (depends on 6) The method of claim 6, wherein removing background from the plurality of images comprises removing portions of the images not having the first and second colors. ### Claim 8 (depends on 1) The method of claim 1, wherein the camera is moved around the body in a substantially circular path or in an arbitrary path. ### Claim 9 (depends on 1) The method of claim 1, wherein the plurality of second fiducials are different from the plurality of first fiducials or are identical to the plurality of first fiducials. ### Claim 10 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. ### Claim 11 (depends on 10) The arrangement of claim 10, wherein the handheld device is configured to process the plurality images by one or more photogrammetry methods to produce a 3D model of the body. ### Claim 12 (depends on 10) The arrangement of claim 10, further comprising a remotely located processor to which the acquired images are transmitted and which is configured to process the plurality images by one or more photogrammetry methods to produce a 3D model of the body. ### Claim 13 (depends on 10) The arrangement of claim 10, wherein the handheld device is configured to at least partially process the plurality images by one or more photogrammetry methods to produce a 3D model of the body, and wherein the arrangement further comprises a remotely located processor to which the acquired images are transmitted from the handheld device and which is configured to at least partially process the plurality images by one or more photogrammetry methods to produce a 3D model of the body. ### Claim 14 (depends on 10) The arrangement of claim 10, wherein the plurality of second fiducials are different from the plurality of first fiducials. ### Claim 15 (depends on 10) The arrangement of claim 10, further comprising a portable stabilization device configured to be held by the person, wherein the stabilization device is configured to reduce movement of the person and to control arm spacing during image acquisition. ### Claim 16 (depends on 15) The arrangement of claim 15, wherein the stabilization device comprises an elongated rod or a walker-style device. ### Claim 17 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 at least one garment comprises a plurality of first fiducials which are photogrammetrically analyzable; and 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 in a remaining area of the reference target, wherein the plurality of second fiducials are photogrammetrically analyzable. ### Claim 18 (depends on 17) The arrangement of claim 17, 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. ### Claim 19 (depends on 17) The arrangement of claim 17, wherein the plurality of second fiducials are different from the plurality of first fiducials. ### Claim 20 (depends on 17) The arrangement of claim 17, wherein the plurality of second fiducials are identical to the plurality of first fiducials. ### Claim 21 (depends on 17) The arrangement of claim 17, wherein reference target has a ring configuration with an inner open region within which the person stands. ### Claim 22 (depends on 17) The arrangement of claim 17, wherein reference target further comprises markings that indicate where the person should place their feet on the reference target.
