EUROFITOVERVIEW

EUROFITisanjointinitiativecofundedbytheEuropeanCommissionaimedat:

FosteringtheglobaltradeofDigitalAnthropometricData

Openingtheuseof3Danthropometrytoproductdesign

SupportingSMEstoenterinternationalmarkets

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

WhatisEUROFIT?

EUROFITproject:overviewandfirstresults4thICE3DBodyScanningTechnologies,LongBeach,CA,USA,1920Nov2013

Huge DigitalAnthropometric Dataavailable now both 1Dand3D

Much moredatawill begeneratedinthe following years

3Ddataexists but3Dexploitation is

NOTAVAILABLEto industry

Few tools for industrialapplication of1Ddatato consumer goodsindustries

EUROFITOVERVIEWWhy EUROFIT?

EUROFITproject:overviewandfirstresults4thICE3DBodyScanningTechnologies,LongBeach,CA,USA,1920Nov2013

# Harmonisation of3Dscan data that enables crossdataanalyses

# 3Denhancing ofexisting 1Ddatabases

# Implementation of3Dshape analysis methods

# Making 3Ddataavailable,usableandaffordable to industry

# Assuring the longterm sustainability of3Ddatatrade platform

# Attracting third party contributors (beyond project)
