在过去的几年里，用于文化遗产应用的3D模型的需求出现了显著增长。所采用的技术已从测量和计算机辅助设计工具和/或传统摄影测量发展到激光扫描和更自动化的基于图像的技术。然而，为一个给定的项目选择最有效的技术并不明显。我们将讨论每种技术，并指出其优缺点。然后，我们将介绍我们的方法，这是一种集成了几种技术的方法，基于我们十多年来获得的经验，以准确和完整地模拟遗产古迹和遗址。我们的经验表明，使用单一技术并不是一种有效的方法。高度详细的结构或场地最好在不同的细节级别上建模。基于图像的建模用于基本形状和结构元素，高精度激光扫描用于精细细节和雕刻表面。为了在适当的环境中呈现网站，基于图像的渲染或全景被用于风景和环境。我们在意大利的两个典型遗址上展示了我们的方法：费拉拉附近的庞波萨修道院和帕多瓦的斯克罗维格尼教堂。
Over the past few years, remarkable increase has occurred in the demand for 3D models for cultural heritage applications. The techniques employed have evolved from surveying and CAD tools and/or traditional photogrammetry into laser scanning and more automated image-based techniques. However, selecting the most effective technique for a given project is not obvious. We will discuss each technique and point out its advantages and disadvantages. We will then present our approach, which is an integration of several technologies and is based on the experience we gained over more than a decade to accurately and completely model heritage monuments and sites. It was clear from our experience that using a single technique is not an effective approach. A highly detailed structure or site is best modeled at various levels of detail. Image-based modeling is used for the basic shape and structural elements, and high-precision laser scanning for fine details and sculpted surfaces. To present the site in its proper context, image-based rendering or panorama is used for landscapes and surroundings. We demonstrate our approach on two typical heritage sites in Italy: the Abbey of Pomposa near Ferrara and the Scrovegni Chapel in Padova.
