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

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)
