| description | The invention discloses an underwater optical measurement error compensation method based on FPP, and the method comprises the steps: carrying out the calculation of a first group of stripe wrapped phases through a phase shift algorithm based on a phase shift sine stripe pattern captured by a camera, introducing Hilbert transform (HT) into the captured stripe pattern, carrying out the calculation of a second group of stripe wrapped phases through the phase shift algorithm, and carrying out the calculation of the second group of stripe wrapped phases; and then, averaging the two groups of stripe wrapped phases to carry out error compensation to obtain a compensated stripe wrapped phase, and finally, carrying out calculation according to the compensated stripe wrapped phase to obtain a corresponding relation between camera pixels and projector pixels so as to realize optical reconstruction of an underwater target. According to the method, the periodical distribution phase error under the muddy water condition i |
