Structured Light
•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 :
• No scanning.
• Correspondence problem among slits.
–  Grid, multiple dots :
• No scanning.
• Correspondence problem among all the imaged features (points, dots, segments,…).
–  Single dot : 
• No correspondence problem. 
• Scanning both axis.
–  Single slit :
• No correspondence problem.
• Scanning the axis orthogonal to the slit.
