The first whole body scanners emerged in 1995. In 1999 a review of whole body scanning techniques and systems was presented (Daanen, H.A.M., Van de Water, G.J. Whole body scanners. Displays 19: 111-120). Now, eight years later, we will present an update of available systems including software and new trends. Laser scanning systems are still the most accurate on the market, but expensive. For the apparel industry some laser systems are developed with less accuracy and lower costs. TC2 is the leading company in patterned light projection scanners due to acceptable price setting. However, scanning accuracy is not as good as in laser scanning. A relatively new method is based on millimeter waves. These scanners can scan through clothing layers, but resolution is poor. Raw scans consist of point clouds. The clouds of each camera have to be aligned first and then merged into one single file. Some post processing is necessary to fill holes due to occlusion effects. Finally, if the processing is done accurately, and the scan is an exact copy of the body, software may be applied to derive additional body dimensions from the scan. The apparel industry is unfortunately still focused on 1D dimension like chest circumference because 3D techniques are still under development. The 1D dimensions generated by the available software (Human Solutions, TC2) are reproducible, but generally do not correspond very well to 1D measures determined by skilled anthropometrists. The question is if the link should be established or if the results should be treated separately. Progress is made in the link between 3D body scans and garment design with software packages like Vidya, Optitex and Narcis. |
