It takes 40s to process data, and after that, the software package ScanWorx or
Anthroscan extracts the measurements of the human body necessary for the imple-
mentation into the computer program to alter the cut of a garment according to the
found measurements (VITUS, 2018). The software package provides the possibility
to correct the obtained body measurements and to add new ones. Using the video
cameras the position of the laser beam on the object is detected outside the fixed
angle. Concerning the triangulation angle and the formation of an optically static
object, the position of a part of the object can be calculated in the direction of the
x-and y-coordinates. To obtain the third object dimension, the triangulation sensor
has been shifted in exactly defined steps in the direction of the z-axis. Using the
information about the distance between steps, the object or body shape is scanned
piecemeal in layers. The Vitus Smart 3D body scanner uses triangulation sensors
directed at the body from different directions (a total of 360 degrees) to scan the
human body in one passage (http://www.human-solutions.com/fashion/front_con
tent.php?idcat¼139&lang¼7, 12.06.2018).
In order to ensure the determination of accurate body measurements, it is necessary
to check and to calibrate the scanner periodically. The person to be scanned should
stand in suitable erect body posture while being scanned and wear undergarment in
bright color tightly fitted. The hair, if longer, should be tied back. To obtain the best
measurement results, it is recommendable to wear a swim cap, Fig. 10.4. It is also
necessary to take off jewelry.
The automatic computer-aided determination of body measurements within a 3D
group of points is used to find the values for a total body measurement; automatic
computer-aided measurements determine the distances between the computer-defined
positions of the measuring points and by measuring the circumference of individual
body parts, Fig. 10.4. The results of automatic computer-aided determination of mea-
surements are generated in a chart upon completion of measurements whereby a
graphical representation of the position of body measurements is given for each taken
measurement. Of the total number of the determined measurements, several measure-
ments were taken separately for the left and right body side, such as arm and shoulder
length; then left and right shoulder length, values of angles that determine the slope of
the individual shoulders; and leg length in the crotch. The values of the circumferences
of individual body parts were separately measured, such as left and right upper arm
circumference, wrist circumference, left and right leg circumference at thigh height,
knee circumference, lower leg circumference, and ankle joint circumference.

10.4.2 Static body analysis
Despite the computer determination of body measurements, scanned body model
analysis provides information about body posture, symmetry, and shape of particular
body parts, with a great significance in clothing construction (Mahnic Naglic and
Petrak, 2017). With body model rotation, it is possible to visualize all details and pos-
sible insufficiencies on the body, Fig. 10.5. Body symmetry can be analyzed according
to the central median body axis and with transversal cross sections in different
body areas.
