We propose a digital speckle correlation method based on the adaptive segmentation of the images of rough surfaces into fragments of any shape with regard for the structure and sizes of all speckles appearing in these images. The method is used for the determination of the fields of displacements of the surface of a duralumin beam containing a lateral fatigue crack under three-point loading.
