Digital Image Correlation (DIC) is an optical measurement method that can measure the deformation and even the appearance of an object. Because of the superiority of non-contact, full field, and low environment requirements, DIC can be used to measure the high temperature mechanical properties of materials in extreme environment. However, there are still difficulties in applying DIC in high temperature displacement measurement, such as heat flow disturbance. It will distort the images acquired at high temperature and affect the measurement accuracy of DIC. In this paper, the disturbance characteristics caused by heat flow are studied and the corresponding correction method is proposed. Firstly, the causes of distortion and the distortion characteristics are analyzed and then verified by experiments. Second, a method for correcting the distortion caused by heat flow is proposed. Finally, the availability of the proposed correction method is verified by experiment.
