More Information
Summary:The invention provides a stripe image energy extraction method, a storage medium and an energy extraction system, and the method comprises the steps: projecting a stripe with the light intensity of In (x, y) to a diffuse reflection white board through a projector, and shooting a stripe image through a camera; solving a wrapped phase diagram of the stripe image; converting the wrapped phase diagram into a cis format through an Euler formula, performing Fourier transform to obtain conjugate Fourier transform for calculating n times of phases, and defining and calculating a polar cross power spectrum R according to Fourier orthogonality; and calculating the energy sum E of the polar harmonics according to the energy function so as to evaluate the nonlinear response of stripe projection. By calculating the energy of each pole, which pole of harmonic waves mainly influence the overall nonlinear response of the stripe projection system can be known, so that a system designer can optimize the system, reduce the infl
