Artificial intelligence improves user experience and work efficiency in digital image correlation (DIC) systems by automating certain tasks, thus improving the competitive ability of local DIC system developers in the global market. The main objective is to detect the type of sample used for material testing, choose the proper measurement tool in the DIC system, and find the proper placement of the tool in relation to the sample. This leads to solving problems of computer vision and image processing, such as object localization and classification, using convolutional neural networks. The open-source PyTorch framework is used for machine learning activities. Tasks like data acquisition, selection and labeling, model selection, training and validation, or hyperparameter optimization are dealt with. As a result, about 95 % of the images were detected successfully.
