Aiming at the over-correction problem of the fringe template measurement method in the lens distortion correction, the phase analysis of fringe-pattern combined with the distortion model is adopted to realize the measurement and correction of the lens barrel distortion. Firstly, the standard cosine fringe-pattern is employed as the measuring template and captured by the camera with wide-angle lens to obtain the distorted fringe-pattern. Four-step phase shifting analysis, which is excellent at spatial localization analysis, is employed for the phase analysis. And then the distortion center and the radial distortion phase are obtained. According to the even-order polynomial model of the radial distortion, the distortion parameters are calculated by numerical curve fitting. Finally, the image correction is achieved according to the distortion parameters and the distortion center. Numerical simulation and real distorted image experiments have been carried out to validate the method.
