1. 3D scanning
knowing our world through movement
Most 3dscanners acquire their data of real world objects by moving through space…
Why 3D scanning ?
- reverse engineering
- tolerance checking & quality control (laserscanning resolution 50 microns)
- digital archiving (cultural heritage)
- prototyping (handmade model to CAD conversion)
- 3D visualisation (fe robot path finding, forensic documentation, etc)
- entertainment industry (avatars, special effects)
Contact & non-contact 3D scanning
contact (older systems)
non-contact (light, sound, xray)
- laser light
- structured light
- (sonic scanner)
- volumetric (medical)

2. Stationary & handheld
3D photo reconstruction
- stereo photogrammetry
- using geometric references

3. Full automatic reconstruction
Taking overlapping pictures
