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)

Stationary & handheld

3D photo reconstruction - stereo photogrammetry

- using geometric references

Full automatic reconstruction Taking overlapping pictures
