determining linear anatomical dimensions of at least a portion of a body of a person in the displayed images using the digitized points and a scale factor for the displayed images; and
making an anatomical circumferential measurement prediction of the person based on the determined linear anatomical dimensions and a known morphological relationship.
2. The method of claim 1 , wherein the points on the plurality of anatomical landmarks are digitized by touching the digital touch screen display of the images at respective anatomical landmarks.
3. The method of claim 1 , wherein acquiring the plurality of images of the person includes acquiring at least two different images corresponding to different views of the person on the digital display, and
digitizing points on the plurality of anatomical landmarks includes digitizing points on anatomical landmarks on each displayed image and determining linear anatomical dimensions of the at least the portion of the body of the person using the digitized points and a scale factor for each displayed image for making the anatomical circumferential measurement prediction.
4. The method of claim 3 , wherein the different views acquired include a front view and a side view of the person.
5. The method of claim 1 , wherein the scale factor is a ratio of pixel to distance.
6. A method for measuring the dimensions of a body of a person, the method comprising:
providing a digital anthropometer on a mobile device;
digitizing anatomical landmarks provided on a plurality of images of at least a portion of a body of a person displayed on the device with established calibration methods;
measuring dimensions of the at least the portion of the body of the person based on the digitized anatomical landmarks across the plurality of images; and
making an anatomical circumferential measurement prediction of the person based on the measured dimensions and a known morphological relationship.
7. A system for measuring the dimensions of a body of a person, the system comprising:
a programmed device comprising a digital touch screen display having an array of pixels and a camera configured to acquire a plurality of images of at least a portion of a body of a person on the digital touch screen display;
a digital anthropometer configured to digitize anatomical landmarks on the images of the at least the portion of the body of the person displayed on the digital touch screen display in order to measure dimensions of the at least the portion of the body of the person; and
a controller configured to make an anatomical circumferential measurement prediction of the person using the measured dimensions and a known morphological relationship.
8. The system according to claim 7 , wherein the anatomical circumferential measurement prediction is a clothing measurement.
9. The system according to claim 7 , wherein the anatomical circumferential measurement prediction is a body measurement.
10. The system according to claim 7 , wherein the anatomical circumferential measurement prediction is a postural measurement.
11. The system according to claim 7 , wherein the programmed device is a mobile, hand-held communication device having at least one positional device selected from the group consisting of a gyroscope, an accelerometer, and a level configured to level the camera.
12. A method of deriving an anatomical prediction using a programmed apparatus including a digital touch screen display and a camera configured to acquire images of a person on the digital touch screen display, the method comprising:
acquiring a first image of a frontal view of a person on the digital touch screen display;
acquiring a second image of a side view of a person on the digital touch screen display;
determining a linear anatomical width dimension of the person from the first image and a linear anatomical depth dimension of the person from the second image; and
making an anatomical circumferential measurement prediction based on the determined linear anatomical width dimension and the linear anatomical depth dimension,
wherein the anatomical circumferential measurement prediction is based on Equations (1) and (2):
