![]() ![]() ![]() Based on the experimental results, the accuracy of point cloud registration yields less than 0.02 m, which meets the accuracy of the 3D model at LoD 300 level. With the point cloud data collected on any Ming and Qing official-style architecture, we further propose a geo-registration mechanism to search for an optimal fitting of the decorative components from the template library on the collected point cloud automatically. The next stage involves the design and construction of different 3D decorative components in the template library with reference to the manuscripts written in the Ming and Qing dynasties’ architectural pattern books. The process of establishing the decorative components template library begins with a remote collection of survey data using a terrestrial laser scanner and digital camera. First, we establish a decorative components template library (or “template library” in short hereafter), which is the first of its kind for the roofs of Ming and Qing official-style architectures. In this paper, we propose a method to ensure that the 3D shape of each roof decorative component is accurately modeled. Although ancient architectures can be surveyed by a 3D laser scanner, the complex geometry and diverse pattern of their roof decorative components make the 3D point cloud reconstruction challenging, or at some points, nearly impossible in a fully automated manner. These roof structures are the essential objects in three-dimensional (3D) modeling of ancient architectures for traditional Chinese cultural preservation. The ancient roof decorative components of the official-style architectures from the Ming and Qing dynasties in China hold both physical and symbolic significance. Through this free-of-charge hypermedia atlas, the tourist accesses 3D photographic and interactive scenes, videos created by 3D point clouds obtained from laser scanning and 3D models available for downloading in ASCII format, and thus acquire a greater knowledge of the touristic attractions in the province of Cáceres. In this sense, this study has three specific aims: to develop a highly reliable methodology for modeling heritage based on a combination of non-destructive geomatics methods to design and develop software modules for interactive 3D visualization of models and to promote knowledge of the historical and cultural heritage of Cáceres by creating a hypermedia atlas accessible via the Internet. The benefits of this project include improved knowledge dissemination of the cultural heritage of Cáceres in a society that demands state-of-the-art tourist information. This study uses panoramic spherical photography and terrestrial laser scanning (TLS) for the geometric characterization and cataloguing of sites of cultural interest, according to the principles of the Charter of Krakow. The three-dimensional (3D) visualization of historical and cultural heritage in the province of Cáceres is essential for tourism promotion. ![]()
