Abstract

Abstract Unmanned Aerial Vehicles (UAVs) are often preferred for modeling cultural heritage buildings due to their costs and time savings. The need for data collection, analysis, processing, and visual presentation in the context of cultural heritage buildings has become prominent, underscoring the significance of the concept of Level of Detail (LoD). The utilization of CityGML LoD standards enhances the performance of visual presentations, decreases the geometric complexity of objects, and enables users to view the model at the desired level of detail within a computerized environment. Within the scope of this study, it is aimed to determine the accuracy analysis of the 3D model for a cultural building, which is named Hekimbaşı Hunting Lodge, at different LoDs. Drawings were created at LoD 0-1-2-3 levels with 418 photographs taken by the UAV photogrammetry method. Additionally, conservative and UAV measures of facade detail at the same LoD were compared in terms of accuracy. As a result, RMSE values for X, Y, and Z axes at LoD3 standard were calculated as 1.394 cm, 0.861 cm, and 0.694 cm, respectively. It has been concluded that the high-accuracy LoD models for the cultural building could be produced using the UAV photogrammetry method at the desired accuracy.

在文化遗产研究中,利用无人机图像进行三维建模的地形测绘的细节层次(LoD)几何分析
摘要:无人驾驶飞行器(uav)由于其节省成本和时间,通常被首选用于文化遗产建筑建模。在文化遗产建筑的背景下,对数据收集、分析、处理和视觉呈现的需求已经变得突出,强调了细节层次(LoD)概念的重要性。CityGML LoD标准的使用增强了视觉表现的性能,降低了对象的几何复杂性,并使用户能够在计算机化的环境中以所需的细节级别查看模型。在本研究的范围内,旨在确定一个名为hekimba狩猎小屋的文化建筑在不同LoDs下的3D模型的准确性分析。图纸在LoD 0-1-2-3级创建,使用无人机摄影测量方法拍摄了418张照片。此外,在相同LoD下,比较了保守和无人机立面细节测量的准确性。计算得到LoD3标准下X、Y、Z轴的RMSE值分别为1.394 cm、0.861 cm、0.694 cm。研究结果表明,利用无人机摄影测量方法可以在要求的精度下生成高精度的文化建筑LoD模型。
