Anthropometry Research Group Institute of Biomechanics

Laboratory

The Human Shape Laboratory of IBV handles with the refinement, calibration and maintenance of measuring instruments that allow to register human shapes, movements and anthropometric dimensions. We also deal with the definition of protocols on how to use those instruments for single measurements or to perform field surveys of diverse populations.

Body scanner

Vitus XXL is a body scanner that quickly generates a 3D representation of the body according to the DIN EN ISO 20685 standard.

The measurement principle is based on optical triangulation, with laser light (eye safe), which is acquired by eight sensor heads, located in four columns. This technology allows highly precise imaging (point density of the scan is 27pt/cm2), and touchless 3-dimensional measurement of the human body.

The scanning volume is 2100 mm in height, 1000 mm in depth and 1200 mm in width, and the person is scanned top down in less than 12 seconds. A weight scale is integrated in the pedestal for subject weight measurement.

With this body scanner IBV has developed anthropometric field surveys of different population groups all around Spain, including adults, children, elderly people and professional populations. Surveys are intended to collect, not only the shape of the body but also measures for garment construction, according to standards ISO 8559 or STANAG 2177.

Foot scanner

INFOOT is a 3-dimensional foot scanner whose operation is based on the optical laser scanning system, developed by I-Ware Laboratory. INFOOT scans a foot form and the anatomical landmark points, and measures automatically almost 20 measuring items (markers are needed) as maximum.

Scanned foot data is used for foot morphological analysis for research purposes, shoe last design, and also shoe selection based on 3D foot data.

As this scanner is easily packable and transportable, IBV has used it to perform large field surveys around Spain to collect data from civilians and military population.

Head scanner

Head Scanner USB is a 3-dimensional Optical Laser scanning system (eye safe) for face and head applications, developed by I-Ware Laboratory. Hair can not be captured, so the user needs to wear a head cap. Scan time is more or less 10 sec/head and raw scanned data is point cloud, saved as binary data that can be exported to other CAD standard formats as CSV, DXF, VRML and STL.

 

Scanning Specifications
Scanning Target Human Head and Face, Land Marker
Scan speed 30 mm/sec (around 10 sec/head)
Data Processing About 20 sec/head
Accuracy 1,0mm step: Y(W)-Z(H)=1mm, X(D)=2mm
0,5mm step: Y(W)-Z(H)=1mm, X(D)=1mm
Data Format FBD (Original data format)
Maximum object size
Less than W=280mm, D=280mm

 



Movement capture

Kinescan is an automatic and real time acquisition system of human movements, designed to perform further kinetic analyses. It accurately registers body movements and allows the sincronization of load platforms with the system Dinascan/IBV, thus getting simultaneous information of the time and point of exerted forces.

It is based on digital video technology with distributed pre-processing. Kinescan/IBV 2011 calculates the position of joints, body segments, kinetic and kinematic parameters in real time, thus allowing a full analysis of 3D movements of human body in few seconds after the gesture performance.



What kind of information do I obtain?

All the kinetic and kinematic parameters can be analysed and graphically represented:

  • Linear variables: position, speed, acceleration.
  • Angular variables: angle, angular speed, angular acceleration.
  • Distances.
  • Kinematis of a rigid body: translation and rotation parameters, using physical markers.
  • Gravity center of body segments.
  • Forces: application point, moments (synchronising with Dinascan/IBV)
  • Energy: potencial energy, kinetic of the translation, rotation and global kinetics.


Manual anthropometry

The manual instruments allow to take direct anthropometric measurements, regardless of the human shape but with more dependence on anatomical landmarks. The measurement protocols are longer and require closer contact with the subject. However the cost is much lower and they allow to take measurements anywhere in the world without having electrical power sources.

The instruments used are determined by the type of magnitudes to be measured. Most of those instruments are marked in metric units, such as millimetres and centimeters.

LINEAR DIMENSIONS

They are the most typical anthropometric measures and include lengths of the long bones and surrounding segments of the arm and leg, breadths and depths of the trunk, and projected dimensions (heights of landmarks from a floor or horizontal offsets from a wall) (Roebuck, 1995).
