The invention discloses an order non-destructive correction method for encoding structured light. The method comprises: a structured light three-dimensional measurement system formed by a projection system and a camera is constructed; a parcel phase of a normal grating sequence and parcel phases phi1 and phi2 obtained by changing a phase shift sequence are obtained by a phase shift method, jump positions D1 and D2 of the two groups of parcel phases are extracted respectively, and then a position P1 needing correction is determined by an intersection calculation method; an absolute phase valuephi(x, y) is obtained by an unpacking operation and the absolute phase value phi(x, y) is processed by using a phase comparison method to correct an order value at the phase jump point P1; and order noises that are not processed are searched by eight-neighborhood traverse and the order values of the order noises are corrected by using a neighborhood phase comparison method. Therefore, an order error problem existing in the encoding structured light is solved; and the order non-destructive correction method is applicable to the order noise correction link for static and dynamic testing.
