近距离摄影技术-包括摄影测量-正在成为构建文物三维（3D）模型的常用工具，特别是在考古研究中。通过摄影测量获得的模型是否可以用于动物考古学研究需要系统的检查。在狗驯化研究的背景下，我们探索通过摄影测量方法获得的狼头骨的3D模型是否在颜色，纹理和最重要的几何形状方面准确地描述了原始头骨。为了回答这个问题，我们比较了用高分辨率表面扫描仪获得的3D模型的拓扑结构，（用作参考几何结构）与使用摄影测量从相同的五个狼颅骨重建的模型。然后使用视觉，定性和两种定量方法对模型进行比较。后者通过几何比较计算了成对3D模型之间的偏差图，然后使用相应的分析进行基于3D地标的几何形态测量方法。我们的结果表明，摄影测量可以生成在纹理、色彩和几何方面具有视觉上令人满意的形态细节水平的3D模型。此外，模型的定量比较显示两个表面之间的平均距离为0.088 mm，平均标准差为0.53 mm。几何形态测量分析显示两个系列扫描的测量误差程度相同（2.04%和1.95%），只有6.31%的形态测量变化是由于采集技术造成的。因此，摄影测量提供了一种低成本，易于携带和简单的替代传统的表面扫描，提供的优势，使其成为一个非常有用的工具，动物考古学研究。(C)2016作者爱思唯尔有限公司出版
Close-range photographic techniques - including photogrammetry - are becoming common tools for constructing three-dimensional (3D) models of artifacts, particularly in archaeological research. Whether models obtained through photogrammetry can be used for zooarchaeological studies requires a systematic examination. In the context of research into dog domestication, we explore whether 3D models of wolf crania, obtained through a photogrammetric approach, accurately describe the original cranium in term of colouration, texture and most importantly, geometry.To answer this question, we compared the topology of 3D models obtained with a high-resolution surface scanner (used as reference geometry) with models reconstructed from the same five wolf crania using photogrammetry. The pairs of models were then compared using both a visual, qualitative and two quantitative approaches. The latter, a geometric comparison computed the deviation map between the pairs of 3D models, which was then followed by a 3D landmark based geometric morphometric approach using corresponding analyses.Our results demonstrate that photogrammetry can produce 3D models with visually satisfying levels of morphological detail in terms of texture, colouration and geometry. In addition, the quantitative comparison of the models revealed an average distance between the two surfaces of 0.088 mm with an average standard deviation of 0.53 mm. The geometric morphometric analyses revealed the same degree of measurement error for the two series of scans (2.04% and 1.95%), with only 6.31% of the morphometric variation being due to the acquisition technique. Photogrammetry, therefore, offers a low cost, easily portable and simple to perform alternative to traditional surface scanning, affording advantages that make it a highly useful tool for zooarchaeological research.
