Phase-Shifting Projected Fringe Profilometry Using Binary-Encoded Patterns

Blog Article

A phase unwrapping method for phase-shifting projected fringe profilometry is presented.It did not require additional projections to identify the fringe orders.The pattern used for the phase extraction could be used for phase unwrapping directly.By spatially encoding the fringe patterns that beer button down shirts for men were used to perform the phase-shifting technique with binary contrasts, fringe orders could be discerned.

For spatially isolated objects or surfaces with large depth discontinuities, unwrapping could be kicker pro comp 10 identified without ambiguity.Even though the surface color or reflectivity varied periodically with position, it distinguished the fringe order very well.
