ABSTRACT Historic Building Information Modelling (HBIM) is the most effective method of rebuilding virtual 3D models of heritage buildings, and constitutes a new information management system in the field of cultural heritage interventions. In this study, photogrammetry based on Unmanned Aerial Vehicles (UAV photogrammetry) was applied as an alternative to Terrestrial Laser Scanning (TLS) for the development of HBIM for historical buildings in a ruinous state, analysing as a case study the Cortijo del Fraile, in Níjar, Almería (Spain). Based on the analysis of the historical information of the building, a photogrammetric survey was carried out with UAV by means of a combination of nadiral and oblique photographs. In this way, a precise characterization of the object was obtained, avoiding the grey areas that are characteristic of TLS. The generated 3D point cloud served as the basis for the virtual reconstruction of an HBIM model focused on both the exterior and interior. In order to ensure reasonable agreement between the parametric model and the ground truth, a validation procedure has been established that restricts the deviations between the two. Finally, a texturizing process is applied to the HBIM model to achieve a photorealistic finish for purposes of visualization, archiving, and recording.

天底斜向无人机摄影测量与HBIM相结合的文化遗产虚拟重建 阿尔梅里亚（西班牙）尼哈尔的 Cortijo del Fraile 案例研究

摘要 历史建筑信息模型（HBIM）是重建遗产建筑虚拟3D模型最有效的方法，构成了文化遗产干预领域的一个新的信息管理系统。在这项研究中，基于无人驾驶飞行器（UAV 摄影测量）的摄影测量被用作地面激光扫描 (TLS) 的替代方案，用于为处于废墟状态的历史建筑开发 HBIM，并以 Cortijo del Fraile 为例进行分析。尼哈尔，阿尔梅利亚（西班牙）。在对建筑物历史信息进行分析的基础上，采用天底和斜面相结合的方式，利用无人机进行摄影测量。通过这种方式，获得了对象的精确表征，避免了 TLS 特有的灰色区域。生成的 3D 点云用作虚拟重建 HBIM 模型的基础，该模型侧重于外部和内部。为了确保参数模型和真实情况之间的合理一致，已经建立了一个验证程序来限制两者之间的偏差。最后，将纹理化过程应用于 HBIM 模型，以实现逼真的效果，用于可视化、存档和记录。
