Abstract： To observe and analyze the internal structural characteristics of leather，two-dimensional images of pig，cattle，and goat leather were obtained by using an Micro-CT（Micro-computed Tomography） scanner， followed by thre-dimensional （3D） reconstruction to generate stereoscopic images. Through various image processing functions such as segmentation， enhancement， and measurement of the Dragonfly software， the study performed arbitrary virtual sectioning on leather samples to thoroughly analyze their internal structural characteristics without damaging the samples. The results showed that pig hair follcles were arranged in groups of three， forming a triangular pattern； the fiber bundles in cattle leather were coarse，with a distinct boundary between the papilary layer and the reticular fiber layer；the fiber bundles in goat leather were fine，and the hair folicle tilt angle was the smallest. Significant variations in folicle inclination angles and depths among pig，cattle，and goat leather provide fundamental data and images for the identification of genuine leather materials.
