Project objectives include

• Creation of a searchable database containing
  thermal profiles, body scans, mapped thermal
  images
• Clustering thermal profiles to facilitate the
  development of garments that better handle heat
  and moisture at the skin surface
• Utilizing technology to solve fit and other
  functional design problems

3D Body Scanner

• Collects 300,000 data points in 12 seconds,
  creates over 80 different body measurements and a
  3D image
• Used in the 3D thermal mapping process
• Create custom apparel, redesign, examine fit,
  study the microclimate

Software can slice the images for microclimate
examination, to determine area volume and
circumference measurements

Thermal camera

• Provides immediate, accurate, visual
  understanding of the thermal emission of the
  human body
• Allows for examination of thermal patterns by
  consumer group
• Useful for apparel design, determination of best
  location of special finishes and special knit or
  woven constructions

Examination of thermal patterns
Heavier individuals typically demonstrate a more
variable heat pattern than thinner individuals
who display a more uniform thermal profile.
15
Environmental chamber, skin thermistors, humidity
sensors
Both temperature and humidity can be controlled
in the environmental chamber
16
Subjects skin temperature can be measured
continually using skin thermistors
Sensors can be placed in areas where there are
special construction techniques or applied
finishes
Sensor allows for continuous humidity data
collection in the microclimate

2D/3D Mapping

• Image registration involves picking landmarks in
  common
• Once landmarks found, the transformation is done
  (in this case a linear conformal transformation)
  and the thermal image is scaled and resized to
  match the body scanned image.

body scanned image.
After mapping, the 3D figure can be manipulated
posed while retaining the thermal information
21
Data mining
Currently over 650 subjects

• Subjects can be broken down by
• gender
• age
• weight and height
• BMI category
• circumference measurements
• level of exercise frequency

22
Thermal Profiling
Normal
Obese
The thermal profiles can be categorized into
spatial regions of similar temperature. These
regions can be provide common areas where extra
(or less) insulatory or moisture wicking
materials are needed.
23
Thermal Profiling

• Sample Analysis of Males, Aged 15-24, Grouped by
  BMI Categories
• Single factor ANOVA looking at radiant thermal
  fluxes
• Shows statistically significant variations in
  means between BMI categories

24
MFDI Web Portal

• Web portal for data querying, visualization and
  analysis of demographic info, body fit and
  thermal profiles
