接触式测角仪是石器和动物考古学分析中常用的工具,尽管由于测量工具、被测物体和测量个体之间的物理相互作用而存在许多缺点。然而,由于缺乏一种简单有效的替代方法,许多领域的研究人员至今仍在使用接触式测角仪。在本文中,我们提出了一种新的角度测量方法,我们称之为虚拟测角仪,它需要一个对象的3D模型上的角度测量虚拟。虚拟测角仪允许快速的数据收集,并用于测量手动测角仪无法物理访问的许多角度。我们比较了人工和虚拟测角仪的观察者内变异性,发现虚拟测角仪更加一致和可靠。此外,虚拟测角仪允许精确复制角度测量,即使在多个用户之间,这对于基于测角仪的研究的再现性很重要。虚拟测角仪可作为开源网格处理软件包Meshlab和Blender中的插件使用,使研究人员可以轻松访问,探索测角仪的潜力,以改进考古方法并解决人类学问题。
The contact goniometer is a commonly used tool in lithic and zooarchaeological analysis, despite suffering from a number of shortcomings due to the physical interaction between the measuring implement, the object being measured, and the individual taking the measurements. However, lacking a simple and efficient alternative, researchers in a variety of fields continue to use the contact goniometer to this day. In this paper, we present a new goniometric method that we call the virtual goniometer, which takes angle measurements virtually on a 3D model of an object. The virtual goniometer allows for rapid data collection, and for the measurement of many angles that cannot be physically accessed by a manual goniometer. We compare the intra-observer variability of the manual and virtual goniometers, and find that the virtual goniometer is far more consistent and reliable. Furthermore, the virtual goniometer allows for precise replication of angle measurements, even among multiple users, which is important for reproducibility of goniometric-based research. The virtual goniometer is available as a plug-in in the open source mesh processing packages Meshlab and Blender, making it easily accessible to researchers exploring the potential for goniometry to improve archaeological methods and address anthropological questions.
