In order to obtain the real-strain of low dimensional materials,the real-strain measurement of low-dimensional materials based on digital image tracking has been proposed. First,the speckles pre-made on the sample or its surface feature points are taken as the tracking objects. Two points are successfully tracked in the real-strain measurement by adopting the improved image correlation formula and selecting the correlative matched template and search region that are determined by analyzing the deformation characteristic of low-dimensional materials. By using the arithmetic of bilinear inter value,the objective is orientated in the 0.01 pixel location,so the measurement precision has been improved. Then,the loads are exerted at grade step. The objects can be successfully tracked. And,the real-strain value under the correlative loads has been obtained. Furthermore,it is an experiment method for studying the dynamic mechanics of low-dimensional materials. The experiment shows that the tracking technology can be fully applied in the real-strain measurement of low-dimension materials. Moreover,the method is also applied in the real-strain measurement of different distances between two speckles. And,the relative calculation error is controlled in 5%.
