研究目的
To document, model, and visualize the ?nce?iz caves in Istanbul, Turkey, using terrestrial laser scanning and virtual reality technology for cultural heritage preservation and tourism promotion.
研究成果
The project successfully created a detailed virtual 3D model of the ?nce?iz caves, enabling immersive and interactive VR experiences. This approach serves as a valuable tool for cultural heritage preservation, education, and tourism promotion, with potential for future enhancements including additional interactive elements and augmented reality applications.
研究不足
The study focused only on the first group of the ?nce?iz caves, with other groups to be documented in future work. The complexity and time consumption of the process were noted as challenges.
1：Experimental Design and Method Selection
The project utilized terrestrial laser scanning (TLS) with a Riegl VZ-400 scanner for high-accuracy 3D mapping of the cave, followed by processing in RiScan Pro software. The 3D model was then integrated into the Unity 3D game engine for VR visualization.
2：Sample Selection and Data Sources
The ?nce?iz caves, located in the ?atalca district of Istanbul, were selected for their cultural and historical significance. Data acquisition involved 46 interior and 50 exterior scans.
3：List of Experimental Equipment and Materials
Riegl VZ-400 terrestrial laser scanner, Nikon D610 camera for colorizing point clouds, Canon EOS 7D Mark II with a Canon EF 70–200 mm f/2.8 zoom lens for gigapixel photography, HTC Vive Pro VR system.
4：Experimental Procedures and Operational Workflow
The workflow included data acquisition by TLS, registration and geo-referencing of scans, segmentation of point clouds, 3D solid modeling in 3ds Max, texture mapping, and integration into Unity for VR visualization.
5：Data Analysis Methods
Point cloud processing and modeling were performed using RiScan Pro, Autodesk ReCap, Geomagic Studio, and 3ds Max. The Unity game engine was used for VR application development.
