Diapositiva PPT
- Principle : Based on the relation between a single camera and a light source which projects a known pattern on the measuring scene.
- The correspondence problem is reduced :
- The matching between the projected pattern and the captured one can be uniquely solved codifying the pattern.
- Stripe patterns :
- Correspondence problem among slits.
- No scanning.
- Grid, multiple dots :
- Correspondence problem among all the imaged segments.
- No scanning.
- Single dot :
- No correspondence problem.
- Scanning both axes.
- Single slit :
- Correspondence problem along the slit, solved by a single orthogonal translation of the light projector with respect to the slit.
- Scanning the axe orthogonal to the slit.
