Requirements of digital body graphics for clothing
1 Scope
This Standard specifies the terms and definitions, requirements and
determination of digital body graphics for clothing.
This Standard is applicable to human body cross-section patterns at control
locations that are obtained by non-contact measuring instrument in clothing
industry, including such as human cross-section graphics obtained by laser,
infrared, and image stitching types.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any
amendments) applies.
GB/T 15557, Standard terminology relating to apparel
GB/T 16160, Location and method of anthropometric surveys for garments
GB/T 23698, General requirements for 3-D scanning anthropometric
GB/T 30548, Verification Method of Anthropometric Data in Clothing Field -
Obtained by Using 3D Measurement Instrument
3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T
15557, GB/T 16160, GB/T 30548 as well as the followings apply.
3.1 feature point of body cross-section contour graphic
The feature point in sectional contour graphics of various parts of a human body
extracted according to size parts in the graphic that is obtained by using a non-
contact measuring instrument.
NOTE: Usually it is center point or extreme point in XY axis direction.
3.2 body section figure
After converting point clouds or solid images obtained using a non-contact
measurement, a cross-section graphic of each control part taken from the
image that is obtained by using software.
4 Requirements
4.1 Acquisition of body graphics and inspection principle
Based on national standard and industry standard measurement methods, use
a non-contact measuring instrument to collect samples to obtain image data.
According to body size parts, section figures of different parts (bust, hip, waist,
neck) are formed. Respectively check whether graphics are closed and
continuous, whether the feature points are complete and the correlation is
correct. Determine whether the feature points are offset and whether the offset
is within the range. Finally, determine the accuracy of the graphics based on
the above parameters.
4.2 Requirements for acquisition of body section figure
4.2.1 Figure acquisition instrument Non-contact automatic human body measuring instrument for clothing. Mobile terminal software or third-party compatible software that can
collect body section figure.
4.2.2 Requirements for figure acquisition test Selection of test sample
It shall select any tested subject (normal body) who shall stand in the standard
standing position. Measurement methods
According to the requirements of GB/T 23698, it shall use an automatic
measuring instrument to measure the tested subject three times to obtain three
sets of measurement results in total.
4.2.3 Figure acquisition methods It can use the software tool of the measurement instrument to
automatically intercept. If there are no automatic intercept function, it can use a third-party
Right hip point P42 □Yes □No
Fore abdominal center
point P43 □Yes □No
Hind hip center point
P44 □Yes □No
Left hip protrusion P45 □Yes □No
Right hip protrusion
P46 □Yes □No If the number of feature points of the figure of each part is consistent
with Figure 1, then the feature points of the figure of the part are complete.
Record as "Yes" in the checklist; otherwise determine as incomplete and record
as "No". If the position of the feature point of each part figure is consistent with
Figure 1 and unique, then the feature point of the part figure is determined to
be unique and recorded as "Yes" in the checklist. If there are multiple or missing
feature points at the same location, it is determined that the feature points are
not unique and recorded as "No" in the checklist.
4.3.3 Interrelationship requirements and inspection of feature points In the coordinate axis of Figure 1, the angle between the line connecting
the center point of each control part and the line connecting the left and right
sides shall be 90° ± 2°. If the angle between the central point line of each control
part and the left and right side points is 90° ± 2°, it is determined that the central
point line of the part is perpendicular to the left and right side points. Record as
"Yes" in the checklist (see Table 5). Record the actual angle. Otherwise, it shall
be determined that it is not vertical. Record "No" in the checklist (see Table 5)
and record the actual angle. In the coordinate axis of Figure 1, the deviation of the ratio of the
coordinate values of the two symmetrical points of each control part graphic
shall be within a certain range. According to the allowable deviation table for
the position of the symmetrical feature points of each part in the coordinate axis
in Table 6, determine whether the position deviation ratio between the
symmetrical feature points of the figure is within the allowable range. If it
complies, determine as “Yes”, otherwise as “No”. It shall respectively check the interrelationship between the feature
points of the graphics of each part. Record in Table 5.
