在土工三轴试验中应用该方法使得试样的变形测量更加简便。通过使用高精度标定板，对该数字图像测量方 法进行了精度分析，结果表明亚像素角点检测方法的轴向和径向测量的标准差都达到了0．02个像素，相对测量精度达到10‘4 数量级。(Triaxial tests in application of this method makes it easier specimen deformation measurements. By using high-precision calibration board, the digital image analysis to measure the accuracy of the method, the results of the standard deviation to measure the axial and radial table Minya pixel corner detection methods have reached 0.02 pixels, relative measurement accuracy of 10 ' 4 magnitude.)
