Abstract
According to an embodiment, a method of determining tool mark identity using machine learning may include: obtaining surface height data of at least two tool strip marks by photographing tool strip marks generated using at least two tools with a three-dimensional (3D) microscope; generating a data set by calculating a cross-correlation coefficient for the surface height data of the tool strip marks; separating the data set into a training set for machine learning training and a test set for verifying a machine learning result; performing the machine learning training to determine whether the tool strip marks are identical using the training set; and verifying a result of the machine learning training using the test set.
