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.
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.

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.

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.
- 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.
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.
CIRCUMFERENCES AND ARCS
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).
