  2. Lecture Schedule • 3D scanning[April 8th– April 19th] • Tutorium • Pac-Man Room [HEEG04] • Thursday[14:00 – 16:00 ] • Friday[12:00 – 14:00 ] • Deadlines • Final Modelafter presentation • Presentation between 24.06 and 28.06 more TBA • Documentation after presentation 3D Vision 2013

  3. 3D Scanning • Team size • 2-3 students • Tasks: • Scan an objectwithourMinolta(near-range) scanner • Photograph thesameobjectandapply aStructurefrom Motion program(Autodesk 123D Catch) • Comparetheoutputs 3D Vision 2013

  4. Structurefrom Motion • Autodesk 123D Catch • YoucanadditionallyusePhotosynth, VisualSFM • Tasks • Take photographs (byyourselforattheinstitute) • Export objectas *.obj • In Geomagic: • Noise removal Waterproof 3D model not necessary, but nice-to-have • Compareoutputtoscannedobject 3D Vision 2013

  5. Example 3D Vision 2013

  6. 3D Scanning - Minolta T • Near-range laser scanner • Triangulation • 1 object per student • Chosen by the teams • Object‘s size: apple - chair • Tasks • Noise removal, registration and merging • Waterproof 3D Model • Evaluation 3D Vision 2013

  7. The Object • Dos • Choose an object which you can access througout the whole term • Ideally a waterproof object • Ideally an object having the size of a pineapple (Ananas) • Don‘ts • Not too many concavities [no pineapple] • Black, transluscent materials are hard to scan 3D Vision 2013

  8. Documentation • 2-4 pages per student • Show intermediate results • Give a short evaluation (meassure the scanner‘s accuracy) • Write about the lessons learned when modelling your object • Do not explain how the scanner works 3D Vision 2013

  9. Presentation • Length • 5-7 minutes • Maximally 12 slides (including title page) • Content • Point out troubles when modelling your object • Give a short evaluation • Compare the model‘s volume with the physical one 3D Vision 2013
