EUROFIT OVERVIEW
EUROFIT is an joint initiative co‐fundedby the European Commission aimed at:
Fostering the global trade of Digital Anthropometric Data
Opening the use of 3D anthropometry to product design
Supporting SMEs to enter international markets
“EUROFIT vision is to unleash the huge potential contained in the increasing number of databases of 3D body scans for the
European consumer goods’ industries”
What is EUROFIT?
EUROFIT project: overview and first results4th ICE 3D Body Scanning Technologies, Long Beach, CA, USA, 19‐20 Nov 2013
• Huge Digital Anthropometric Data available now – both 1D and 3D
• Much more data will be generatedin the following years
3D data exists but3D exploitation is
NOT AVAILABLE to industry
• Few tools for industrial application of 1D data to consumer goods’ industries
EUROFIT OVERVIEWWhy EUROFIT?
EUROFIT project: overview and first results4th ICE 3D Body Scanning Technologies, Long Beach, CA, USA, 19‐20 Nov 2013
# Harmonisation of 3D scan data that enables cross‐data analyses
# 3D enhancing of existing 1D databases
# Implementation of 3D shape analysis methods
# Making 3D data available, usable and affordable to industry
# Assuring the long‐term sustainability of 3D data trade platform
# Attracting third party contributors (beyond project)

Homology
Point‐to‐point correspondence that
• enables interpolation of shapes
• enables statistical analyses
• enables fast body part selections
PROJECT RESULTS – 3D harmonisationBasis of the approach followed
Homologous mesh structure – Homodel
• Single mesh of 50K vertices and 99K faces
• Key anatomical landmarks associated to vertices
• Master semantic edges enabling body part focus
• Skeleton enabling posture corrections

Homodel
Fitting of a template mesh equipped with a skeleton to a 3D scan using a set of anatomical references.
Made in three automated steps:
• Template posing and scaling• Template fitting to scan surface• Post processing of slit areas
Fitting the scan with a coarse mesh defined by a fixed set of anatomical references. The coarse mesh is progressively broken down to fit the scan surface. It requires higher and fix number of landmarks and a finer slit modelling prior to the fitting but can achieve a higher quality (<0.04mm).It requires a final conversion to the homologous structure.
