Abstract: Three-dimensional reconstruction technology has been widely applied in various fields of archaeological excavation and research. Through the three-dimensional reconstruction of stone artifacts, more accurate and objective data can be obtained, inspiring many new researchmethods and perspectives. Among these applications, Multi-view 3D Reconstruction (MVR) technology does not require professional equipment and techniques. Instead, all data collection can be accomplished with a digital camera and a computer. MVR technology has the benefits of easy operation, lower cost, and high precision. We can obtain precise values for cortex area, flake scars, specimen volume, knapping orientation, angle of points, and so on, through the three-dimensional model generated by Agisoft Photoscan software. Data such as the dense cloud file, model file, digital elevation model (DEM), or orthophoto can also be imported into other software to expand the research. Considering the advantages of this technology, we could adopt it as a commonly used tool for both archaeological excavation and research.
