3D Scanning

Team size 2-3 students – 1 Object per student

Tasks: Scan an object with our Minolta

laser scanner OR with our AiconStructured Light Scanner (new)

Photograph the same object and apply aStructure from Motion program(Autodesk 123D Catch / ReMake)

Compare the outputs

3D Vision 20173

3D Scanning – Minolta / Aicon

Near-range laser / Structured Light scanner Triangulation

1 object per student Bring your own object

Tasks Noise removal, registration and merging Waterproof 3D Model Evaluation

3D Vision 20174

Structure from Motion

Autodesk 123D Catch / ReMake You can also use Photosynth, VisualSFM

Tasks Take photographs (by yourself or at the institute) Export object as *.obj In Geomagic:

Noise removalWaterproof 3D model not necessary, but nice-to-have

Compare output to scanned object

The Object

Dos Choose an object which you can access througout the whole

term Size: apple - pinapple Ideally a waterproof object Matte surface, moderately textured

Don‘ts Not too many concavities [no pineapple] Black, translucent or shiny materials are hard to scan

3D Vision 20177

Dont‘s!

3D Vision 20178

Extreme brightness differencesTransparent /translucentshiny

Too complex / cavities deformableToo simple / symmetric

Geomagic

Professional 3D editing software Registration, noise removal, hole filling etc. Validation

On Lab PCs: Geomagic Studio 12 installed @ Home: Geomagic Studio is discontinued since 2015 You could e.g. use trial of Geomagic Wrap (fully functional for

15 Days)

3D Vision 20179

Documentation

2-4 pages per student Show your 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
