| description | Intensity saturation can induce phase error and, thus, measurement error in fringe projection profilometry. To reduce saturation-induced phase errors, a compensation method is developed. The mathematical model of saturation-induced phase errors is analyzed for <i>N</i>-step phase-shifting profilometry, and the phase error is approximately <i>N</i>-folder of the frequency of the projected fringe. Additional <i>N</i>-step phase-shifting fringe patterns with initial phase-shift <i>π</i>/<i>N</i> are projected for generating a complementary phase map. The final phase map is obtained by averaging the original phase map extracted from the original fringe patterns and the complementary phase map, and then the phase error can be canceled out. Both simulations and experiments demonstrated that the proposed method can substantially reduce the saturation-induced phase error and realize accurate measurements for a highly dynamic range of scenarios. |
