        After combining the corner extraction method with the digital image correlation method, a new algorithm called the corner correlation method (CCM) was proposed, realizing a high-precision measurement for the displacement field and strain field on the surface of the specimen. It is applicable to the model with complex damage on the calculated surface. The errors of cross-crack speckle pattern and corner pattern are compared, and it was concluded that the errors of corner pattern of transverse and longitudinal cracks are less than that of the speckle pattern. The calculation accuracy of the corner correlation method is evaluated and verified by numerical simulation, static tensile test and dynamic uniaxial compression test respectively. It was found that the calculation accuracy was the highest with the Newton iteration method. The displacement calculation accuracy is about 0.01 pixels and the resolution of the measurement system for the strain test was on the order of 10-4under dynamic load.
