在本研究中，描述了一种简单的方法来获得不同尺寸和特征的岩画的三维数字模型，并评估了它在研究这一文化遗产中的实用性。在这项研究中，我们使用了低成本的摄影测量软件和消费级数码相机，没有使用任何其他测量技术。为了检验这种方法，在加利西亚（西班牙）进行了三次实地调查研究。利用所提出的方法，可以在基本设备上获得三维数字模型，并且可以借助卡尺方便地评估其精度。考虑到它们提供的分析可能性，3D数字模型可以极大地帮助考古学家、保护主义者和岩石遗址管理者研究、理解和解释岩画。低成本的数字图像相关摄影测量是一种简单而通用的技术，可用于该文化遗产的记录、分析和传播。与其他3D建模技术一样，它不仅是传统技术的补充，而且确实可以取代传统技术，因为它的简单性和3D数字模型的交互性，可以很容易地插入到网络中。
In the present study a simple method is described for obtaining 3D digital models of petroglyphs of different sizes and characteristics and its usefulness, in the study of this cultural heritage, is evaluated. For this research we used low-cost photogrammetric software and consumer-grade digital cameras, without any other surveying techniques. In order to test this methodology, three field research studies were carried out in Galicia (Spain). By means of the proposed methodology, 3D digital models are obtained using basic equipment and its accuracy can be evaluated easily with the help of a calliper. Given the possibilities of analysis that they offer, 3D digital models can substantially assist in the study, comprehension and interpretation of petroglyphs by archaeologists, conservationists and rock-site managers. Low-cost digital image correlation photogrammetry is a simple and very versatile technique in its application to the documentation, analysis and diffusion of this cultural heritage. As has occurred with other 3D modelling techniques, it not only complements traditional techniques but can indeed substitute them, owing fundamentally to its simplicity and the interactive character of the 3D digital models, that can easily be inserted in the web.
