Having great historical, scientific and artistic research value, the archaeologically unearthed Terracotta Warriors of the first emperor of the Qin Dynasty are very precious physical materials of the Qin Dynasty. Their representation of “thousands of people with thousands of faces” has attracted much attention and is considered to be a true portrayal of Qin people. In modern anthropometry, head and face features are widely used to analyze the genetic relationship between ethnic groups because they are primarily affected by genetic factors rather than environmental factors. We collected high-precision 3D point cloud data from the heads of 50 samples of Terracotta Warriors and extracted their head and face features. Using the methods of sample correlation analysis and data size-sorting statistical analysis, we compared these results with the head and face features of 29 modern groups or areas. The results show that the head and face features of the Terracotta Warriors are completely different and highly correlated, and have little difference with those of modern nationalities, quantitatively defining the relevant features of Terracotta Warriors.
