Abstract

Abstract:

Lithic artefacts are a kind of important material remains left by prehistory humans, which are the media containing the information about evolution of human cognitive, technology and behavior. And it is important for Paleolithic archaeologists to conveniently and accurately observe, illustrate, measure and show the lithic artefacts. So far, the software, Agisoft PhotoScan, has been more and more widely applied in the field of archaeology, China. Compared to other artefacts, the shape and scar pattern of each lithic artefact are unique and special. By trial and error, we have established a method, being easy to master, that using Agisoft PhotoScan to build lithic artefact 3D model. Then we introduce the application of 3D model in the Paleolithic archaeology, including how to observe and illustrate lithic artefacts, how to measure lithic artefacts, how to show lithic artefacts.

Key words: Knapped lithics, Agisoft PhotoScan, 3D model
