Digital image correlation method is applied in many field like strain measurement, fluid measurement and displacement measurement of structural object. This method requires the sub-pixel accuracy to increase the resolution power of positioning the template image. Therefore, different types of sub-pixel estimation algorithms have been developed. One of the most commonly used sub-pixel estimation method is gradient based method and others are correlation interpolation method and intensity interpolation method. In this research, we evaluate and compare the estimation error of two types of sub-pixel estimation method by using computer simulated image. As a result, we confirm issues of systematic error in correlation method and best combination of gradient based method and intensity interpolation filter.
