Atos 3d digitizer scopes of applications
ATOS3D Digitizer – Scopes of Applications

Industrial Applications

  • Inspection

  • Reverse Engineering

  • Rapid Prototyping

    Medical Applications

  • Orthetics

  • Forensics

  • Medical

    Computer Graphics

  • 3D Character Animation

  • Internet 3D Product Presentations

  • Virtual Reality

    Cultural Applications

  • Documentation / Research

  • 3D Copying / Replications

  • Monitoring


Atos 3d digitizer
ATOS3D Digitizer

Features

  • Mobile 3D Scanner

  • Changeable measuring volumes

  • Robust, compact sensor design

  • Very fast measuring sequence: under 1 second

  • Simple operation

  • Can be used as stand alone digitizer or as ATOS I XL (with TRITOP)

  • Can be integrated easily in complete measuring set up, on robots or in combination with rotation tables

    Stereo Camera Technique

  • Photogrammetric calibration

  • Self monitoring

  • Online checks

  • High detail resolution


Atos workflow
ATOS Workflow

  • Freehanded or automated sensor positioning (robot)

  • Projection of fringe pattern

  • Measurement patches consist of up to 4 million 3D points

  • Automatically transformation of all measurements/different views into object coordinate system


Atos workflow1
ATOS Workflow

  • Results

    • Triangular mesh

    • Point cloud

    • Sections


Atos 3d digitizer1
ATOS 3D Digitizer

  • White-Light-Measuring-System

    • Non-Invasive (No Laserlight)

    • Non-Contact


Atos 3d digitizer2
ATOS 3D Digitizer

  • Variable Measuring Volumes

    • Object sizes from coin to monument

    • Adjustable resolution


Atos 3d digitizer3
ATOS 3D Digitizer

  • Stereo-View-System

    • Self-Controlling-Calibration

    • Variable Triangulation Angels (for capturing undercuts)

    • Fewer measurements necessary


Atos 3d digitizer4
ATOS 3D Digitizer

  • Non-Cooperative Objects Surface

    • Different exposure times allow to capture data on dark and bright surfaces

    • For glossy surfaces, data can be calculated based on the images from one camera only



Atos 3d digitizer6
ATOS 3D Digitizer

  • Data handling

    • Using 64-Bit Technology in combination with Linux-operating-system allows fast handling and computation of large volume data sets


Atos 3d digitizer7
ATOS 3D Digitizer

  • Mobility

    • Laptop and TRITOP

    • Small suitcase for transporting

  • documentation and shape analysis during restoration process after excavation in 1999 near Losinj, a Croatian island

  • Ancient greece bronze sculpture of Apoxyomenos, 4th century BC

  • Topomatika d.o.o. used TRITOP and ATOS-System in cooperation with the Croatian Conservation Institute


Documentation of architectural monuments st jacob s cathedral in ibenik
Documentation of architectural monuments St Jacob’s Cathedral in Šibenik

  • The Cathedral of St. Jakov (St. Jacob) in Šibenik is a triple nave basilica with three apses and a cupola (height of interior is 32 m). It was consecrated in 1555

  • enlisted in UNESCO's world heritage in 2001

  • Art-historical and geometrical documentation and shape analysis of sculptures and façade details

  • Ministry of Culture RH and regional office for conservation in Šibenik


Documentation of architectural monuments charlesbridge

  • Capturing of 3D-Shape of the statues of the Charlesbridge in Prague with TRITOP - and ATOS-Systems by the State Institute for the Care of Culture in cooperation with MCAE Systems s.r.o. in 1999

  • Documentation and Monitoring of the 8m high stone statues deriving from 18th century

  • App. 350 single scans were taken for the Statue of St. Vojtech


Documentation of architectural monuments maximilian 1 s tomb
Documentation of architectural monumentsMaximilian 1´s Tomb

  • Art-historical and geometrical documentation during restoration process in 2000-2003

  • the 3m x 5m x 5m large cenotaph (empty tomb) was built ca. 1560 and consists of black marble, 24 reliefs of white marble as well as of bronze figures

  • University of Applied Science Mainz used TRITOP and ATOS-System in cooperation with Landesbaudirektion Tyrol


Deformation analysis deterioration monitoring
Deformation Analysis / Deterioration Monitoring

  • Heads of Maison Tavel, Geneva

  • Architectorial details, originally painted stone

  • Deriving from the end of the middle age

  • Ecole d´íngénieurs de Genève


Deformation analysis deterioration monitoring1
Deformation Analysis / Deterioration Monitoring

  • 2D Images allow only a subjective estimation of damage and degradation

  • The actual scan-data from 2005 were compared to scan-data of plaster moldings from 1911

  • Thus a qualitative and quantitative analysis is possible


Reproduction
