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

  • 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

  • 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
