Paper Abstract

A non-contact body measurement system (BMS) is under development for use in making made-to-measure apparel, and for other applications related to body measurement. The BMS design which consists of six stationary structured-light projectors and six CCD cameras is presented. The system acquires two-dimensional images of sinusoidal projected patterns utilizing a phase-shifting technique similar to phase measurement profilometry. Given calibrated projector and camera geometrical parameters, the solution for calculating three-dimensional surface points of a human body from the camera images is developed. A statistical error analysis is presented for the phase measurement and the three-dimensional point solution in terms of system measurement errors. An operating developmental implementation of the BMS is described and pictured. Contour plots of test subjects taken with this system, showing digitized three-dimensional surface segments, are presented and discussed.
