Precise measurements are the key for making digitally tailored garments. Therefore it is necessary to have measurement defined by the measurement extraction profile which would correspond to apparel basic block construction. A block is a foundation pattern constructed to fit a specific human. A block should be defined as formulas to the CAD/CAM system (Gemini) or altered by CAD/CAM systems (Lectra, Optitec, Gerber, etc) to fit an individual figure using personal measurements.
The data captured by body scanner can be very precise depending on the technology (white-light, infrared depth sensor, etc) and the amount of detectors (lasers/sensors/lights) used. The precision of measurements obtained depends on how exactly the body scanner detects the body surface and how good is the measurement extraction profile. At the moment, there can happen that even two different versions of scanners from the same company can produce results with 3-4cm difference in knee circumference (depending on the knee circumference).
After considering over 10 000 body scans, I have come to conclusion, that the existing scanners do not detect well enough crotch area (the region of the body where the legs join the torso, and are often considered to include the groin and genitals). Measurement extraction profiles do not allow to map crotch point (the crotch point is the point starting from which the cross-section of the body changes from one circle to two circles) as it is constructed in the persons block where the legs join together and the bottom of the crotch defines one end of the inseam.
We should have a standardized "human" prototype as a tool to compare results produced by different scanners in order to secure the precision of the body scanner data and measurement extraction profiles.
