Abstract
Pottery is an important material in archaeological studies, and the accurate classification of pottery shapes largely depends on the experience and knowledge of archaeologists. In this paper, pottery collected from the Gansu-Zhanqi site was used for sampling. Three-dimensional (3D) models of the pottery were obtained using 3D scanning, and a computer-assisted pottery typology was studied through quantitative analysis and elliptic Fourier descriptor analysis. This method, which can enhance and supplement the traditional methods of classifying pottery in archaeology, enriches the parameters and breadth of pottery analysis, represents a new means of exploring and experimenting with objective classification, and provides a new tool for traditional archaeological analysis methods.

Summary
Pottery is a common and important ancient material in the study of archaeology. The classification pattern of each object is an important factor used to determine the type and age of an archaeological culture. Considerable pottery was unearthed at the Zhanqi site, including jars, lis, basins, dous, and bottles. 62 saddle jar examples, which are the representative pottery from the Zhanqi Site, were scanned. It is important to note that since the research on pottery shapes requires less accuracy than a virtual display, the model analysis is not affected by the software processes in this paper. Over the past few years, scientists have introduced several data extraction methods for three-dimensional pottery models, including Stefan Spelitz [20], Rasheed [21], Măruţoiu [22], and Revello Lami [23]. Considering the methods and functions of this article, the extraction and analysis of the dimension data are based on the XZ plane in the model, which shows the different calibres and heights of the ears. The extraction and analysis of the curve data are based on the YZ plane in the model, which shows differences in the overall shapes
