The approach employs Devernay-operator-based concentric circle edge extraction for precise binocular camera calibration and a parallel-optimized initial value search for real-time subpixel matching. Experiments using a binocular-stroboscopic system on a rotating blade show a maximum unidirectional displacement error of \u22642\u00a0\u03bcm. At 6000\u00a0rpm, peak deformations along the X, Y, and Z directions are 234, 258, and \u2212193\u00a0\u03bcm, respectively, with a total maximum deformation of
