摘要
将数码相机用于土三轴试样变形的图像采集,提出了一种基于数码相机的土三轴试样变形的数字图像测量方法.通过与常规土三轴试验测量结果对比,说明了该方法的可行性和优越性,它不仅可以克服常规三轴试验方法中存在的诸多缺陷,而且具有较高的测量精度,是一种简单、有效且有广阔发展前景的测量方法.
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.
