Abstract

The characterization and correction of lens distortion is an important part of optical measurement. This work analyzes the formation mechanism of color fringes and multiplication moiré, and discusses modification of the color CCD moiré method for correcting lens distortion. A demosaicing algorithm was used to simulate the color fringes in a CCD moiré pattern. We then performed a detailed analysis of the carrier field, and adopted a universal polynomial distortion model to characterize lens distortion, which increased the accuracy of distortion correction. Comparison experiments verified the feasibility of the modified method and the correctness of the formation mechanism for color CCD moiré. The modified method was then applied to lens distortion correction in the DIC measurement process, effectively reducing errors in displacement measurement.
