技术背景background
由于三维数字图像相关技术（dic）具有出色的准确性、稳健性和易用性，因此已广泛应用于应变测量。但是，对于需要高放大倍数的样品，3d测量仍很难获得。这主要是由于缺乏具有足够景深的光学元件以从不同视角获取3d分析所需的两张高放大率图像。
three-dimensional digital image correlation (dic) has found widespread popularity for strain measurements due to its excellent accuracy, robustness and ease of use. however, 3d measurements have been difficult to obtain on specimens where high magnification is required. this is mainly due to the lack of optics with sufficient depth-of-field to acquire two high magnification images from different viewing angles.
立体显微镜克服了这些景深限制。然而，立体显微镜的内部结构妨碍了使用传统模型（例如seidel镜头失真）对图像失真进行适当校正。这些未经校正的图像将导致形貌和应变测量产生严重的偏差。事实上，观察中数千微应变的偏差量级并不鲜见。
stereo microscopes overcome these depth-of-field limitations. however, the internal construction of stereo microscopes prevents proper correction of image distortions using traditional models, such as seidel lens distortions. these uncorrected images will result in severely biased shape and strain measurements. in fact, it is not uncommon to observe bias levels of several thousａnd microstrain.
为了克服这个问题，csi公司开发了一种易于使用的标定方法，该方法不会遇到与传统参数失真模型相关的问题。 该标定方法计算立体显微镜的非参数畸变场，并已被证实可完全消除测量中的形貌和应变偏差。
to overcome this problem, correlated solutions, inc., has developed an easy-to-use calibration method that does not suffer from the problems associated with traditional parametric distortion models. the calibration method computes the non-parametric distortion fields of the stereo microscope and has been shown to completely eliminate shape and strain bias from the measurements.
