| Abstract: | The digital camera is used to collect the pictures of specimen deformation. The digital image measurement of specimen deformation in triaxial test based on digital camera is put forward. By comparing the measurement results with that of traditional method, it is shown that the digital image processing technique can overcome many shortages encountered in traditional test and has high accuracy. The digital image processing technique is not only a feasible method but also a simple,convenient and valuable method. |
