Abstract
The materials are measured and analyzed by the UTM combined with a contact type extensometer so as to analyze the characteristics such as strain-stress curve. However, the JIG and Fixture utilized in the UTM according to the standard [ASTM] can not only scratch the specimens but also have a serious distort on test result by the weight of the ZIG itself. In this paper we propose a moncular vision based visual extensometer [VE] securing the measuring accuracy using a new cross correlation in detecting the two feature points previously marked on the specimen from two successive images, and verify the usefulness of this VE through a real experiment on the UTM.
