3D Scanning


3
Team size
 2-3 students
Tasks:
 Scan an object with our Minolta
(near-range) scanner
 Photograph the same object and apply a
Structure from Motion program
(Autodesk 123D Catch)
 Compare the outputs

Structure from Motion


4
Autodesk 123D Catch
 You can additionally use Photosynth, VisualSFM
Tasks
 Take photographs (by yourself or at the institute)
 Export object as *.obj
 In Geomagic:
Noise removal
Waterproof 3D model not necessary, but nice-to-have
 Compare output to scanned object

 Triangulation
1 object per student
 Chosen by the teams
 Object‘s size: apple - chair
Tasks
 Noise removal, registration and merging
 Waterproof 3D Model
 Evaluation

The Object


7
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

Documentation

8
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
