Coded Structured Light Techniques
- Pattern placed with single vertical displacement from camera.
- Vertical slits used as guides to search the dots.
- Dots are used to decode the horizontal lines.
Both axes coded / Dynamic / Binary / Absolute
Posdamer - Altschuler 1981
- The projection of n patterns are needed to code 2n columns.
- Projection of an initial pattern without codification to extract dot positions.
Column Coded / Static / Binary / Absolute
Minou ‘81, Inokuchi ‘84. The same pattern proposal.
Sato ‘86. Better segmentation, positive & negative images.
Mundy ‘87. Sensor implementated in hardware.
Hattori ‘95. Low heat irradiance. Semiconductor Laser.
Muller ‘95. Re-implementation.
