| 摘 要： | 在目前常规图象分辨率基础上，对数字图象相关测量方法的灵敏度进行分析，给出了位移和应变测量的灵敏度，并讨论了影响灵敏度的有关因素，进而指出，数字图象测量系统特别适合于各种位移场的大变形场的定量测量，在配制了相应的光学观察仪器后。也基本适合一般变形场的测量。

| Abstract: | Based on the conventional image resolution, an analysis for the measurement resolu-tion of porrelative system with digital image is presented. The sensitivities of displacement and strainmeasurement are pointed out, and the factors affecting these sensitivities are discussed. As a result,it can be concluded that the digital image measurement system is particularly suituble for the quantitutive measurement of various displacement and large deformation. To allocate a related observingapparatus, it can be applied to general deformation measurement. |
