“…Based on the cited references [22][23][24][25][26][27][28], we can pronounce those methods based on DIC correlation as being the gold standard in optical methods of material tensile testing and have significant advantages. Our proposed method can be the alternative way to automatize tensile tests using image functions which differ from classical correlation and achieve comparable results.…”

This article deals with the use of contactless measurement with a high-resolution imaging device during tensile testing of materials in a universal tearing machine (UTM). Setting the material parameters in tensile testing is based on changes in the geometrical properties of the sample being tested. In this article, authors propose the method and system for automated measuring the height, width, and crack occurrence during tensile testing. The system is also able to predict the location of crack occurrence. The proposed method is based on selected algorithms of image analysis, feature extraction, and template matching. Our video extensometry, working with common inspection cameras operating in visible range, can be an alternative method to expensive laser extensometry machines. The motivation of our work was to develop an automated measurement system for use in a UTM.
