Abstract

A robust and accurate method is proposed to extract the isotropic points from min-max scanned photoelastic images automatically. The method uses a multiple layered window with four-change condition to extract the isotropic points. Test of this method on both the simulated and experimental obtained isoclinic images and direction images is shown. An exact position was found for the simulated images and a difference of about 1.4 pixels is achieved for the experimental ones. The whole scheme is very simple, fast, and effective to extract the isotropic point for structural design purpose.
