of some of the companies that produce body scanners in a rapidly changing market.
They also list 3-D scanning apps and handheld scanners.
Laser: Laser scanners are considered the gold standard of 3-D body scanning. In
booth form, these scanners are generally configured with sensors equally spaced
around the body instead of focused on the front and back of the body. Laser scanners
are somewhat sensitive to color and generally will not scan black objects well, though
this can be adjusted to improve capture at the expense of the speed of the scan (nor-
mally about 12s). Scanning can occur in the presence of white light, so the person
being scanned does not need to be isolated from the person taking the scan. The major
company currently providing laser scanning is Vitronic (Human Solutions).
Structured light: Structured light scanners take scans much more rapidly than laser
scanners, but the data from white light structured scanners can be noisy and require
more postprocessing. These scanners generally take multiple scans and then use com-
puter algorithms to smooth the surface of the scan as they construct the 3-D digital
model from the sensor data. The primary manufacturers of white light scanners
acquire data from the front and back of the body and generate side data as part of
