Traditional anthropometric methods are inadequate for both the
amount of data collected and the time required to collect it. The subject
of this thesis is a study of the feasibility of producing a socially
acceptable whole body measuring machine capable of obtaining three dimensional
shape data of the human body. In particular the
investigation of a novel idea ( British Patent No. 85.24473) using
television cameras and a particular form of structured light
illumination. The geometry of the system is explained and some aspects
of lens distortion investigated. A television camera interface has been
designed incorporating a single card computer to capture the video
image and to transfer it to a Macintosh computer. Programs written for
both the computer and the interface allow measurements to be made of a
significant part of the human body and have produced results in both
tabulated and graphical form.
Compared with existing systems such as stereo-photogrammetry,
Moire topography, light slit scanning and rasterstereography which
require sophisticated image analysis techniques, the new system
provides a more direct read-out of data.
Body sway effects have been considered and the equipment has been
used to measure the amount of sway in a small group of people.
