Cultural landscapes are those that are shaped through the combined forces of cultural and natural activity, typically over a long period that may reach back to historic and prehistoric times. Amongst these, the documenting, modelling and visualisation of cave landscapes have always been particularly important for scientific communities such as speleology. In the current state of the art, terrestrial laser scanning provides a level of documentation of objects whose accuracy cannot be achieved by conventional methods. In addition to the highly accurate metric and geometric information, visual information brings incredible richness to the presentation of data. Virtual reality (VR) allows individuals to immerse themselves within virtual environments to explore monuments and other cultural heritage sites up close. More and more, VR systems are available at lower prices and are not only limited to VR labs. In this paper, we present research on the generation of a virtual 3D model of the İnceğiz caves, located at the Çatalca district of Istanbul, Turkey, and its integration within the Unity 3D game engine. This project, carried out as a collaboration between BİMTAŞ, a company of the Greater Municipality of Istanbul, Turkey and the Photogrammetry & Laser Scanning Lab of the HafenCity University Hamburg, Germany, aimed at developing an immersive and interactive VR visualisation of the cave for the HTC Vive Pro VR system. The entire workflow, from data acquisition to VR visualisation, is described here in detail with particular emphasis given to the 3D modelling of the cave and its integration within a VR environment.

通过虚拟访问保留过去的知识:从3D激光扫描到伊斯坦布尔ÇatalcaİnceğizCaves的虚拟现实可视化

文化景观是指文化和自然活动共同作用下形成的景观,通常在很长一段时间内可以追溯到历史和史前时期。在这些之中,洞穴景观的记录,建模和可视化对于科学界如洞穴学一直特别重要。在当前的现有技术中,地面激光扫描提供了对象水平的文献记录,其精度不能通过常规方法来实现。除了高度精确的度量和几何信息,视觉信息还为数据表示带来了难以置信的丰富性。虚拟现实(VR)可使个人沉浸在虚拟环境中,以近距离探索古迹和其他文化遗产。越来越多,VR系统的价格较低,不仅限于VR实验室。在本文中,我们介绍了位于土耳其伊斯坦布尔Çatalca区的İnceğiz洞穴虚拟3D模型的生成及其在Unity 3D游戏引擎中的集成的研究。该项目由土耳其伊斯坦布尔市大城市BİMTAŞ与德国汉堡HafenCity大学摄影测量与激光扫描实验室合作完成,旨在为该洞穴开发沉浸式和交互式VR可视化HTC Vive Pro VR系统。这里详细描述了从数据采集到VR可视化的整个工作流程,并特别强调了洞穴的3D建模及其在VR环境中的集成。在本文中,我们介绍了位于土耳其伊斯坦布尔Çatalca区的İnceğiz洞穴虚拟3D模型的生成及其在Unity 3D游戏引擎中的集成的研究。该项目由土耳其伊斯坦布尔市大城市BİMTAŞ与德国汉堡HafenCity大学摄影测量与激光扫描实验室合作完成,旨在为该洞穴开发沉浸式和交互式VR可视化HTC Vive Pro VR系统。这里详细描述了从数据采集到VR可视化的整个工作流程,并特别强调了洞穴的3D建模及其在VR环境中的集成。在本文中,我们介绍了位于土耳其伊斯坦布尔Çatalca区的İnceğiz洞穴虚拟3D模型的生成及其在Unity 3D游戏引擎中的集成的研究。该项目由土耳其伊斯坦布尔市大城市BİMTAŞ与德国汉堡HafenCity大学摄影测量与激光扫描实验室合作完成,旨在为该洞穴开发沉浸式和交互式VR可视化HTC Vive Pro VR系统。这里详细描述了从数据采集到VR可视化的整个工作流程,并特别强调了洞穴的3D建模及其在VR环境中的集成。位于土耳其伊斯坦布尔的Çatalca区,并将其集成到Unity 3D游戏引擎中。该项目由土耳其伊斯坦布尔市大城市BİMTAŞ与德国汉堡HafenCity大学摄影测量与激光扫描实验室合作完成,旨在为该洞穴开发沉浸式和交互式VR可视化HTC Vive Pro VR系统。这里详细描述了从数据采集到VR可视化的整个工作流程,并特别强调了洞穴的3D建模及其在VR环境中的集成。位于土耳其伊斯坦布尔的Çatalca区,并将其集成到Unity 3D游戏引擎中。该项目由土耳其伊斯坦布尔市大城市BİMTAŞ与德国汉堡HafenCity大学摄影测量与激光扫描实验室合作完成,旨在为该洞穴开发沉浸式和交互式VR可视化HTC Vive Pro VR系统。这里详细描述了从数据采集到VR可视化的整个工作流程,并特别强调了洞穴的3D建模及其在VR环境中的集成。德国汉堡港口城市大学的激光扫描实验室旨在为HTC Vive Pro VR系统开发洞穴的沉浸式和交互式VR可视化。这里详细描述了从数据采集到VR可视化的整个工作流程,并特别强调了洞穴的3D建模及其在VR环境中的集成。德国汉堡港口城市大学的激光扫描实验室旨在为HTC Vive Pro VR系统开发洞穴的沉浸式和交互式VR可视化。这里详细描述了从数据采集到VR可视化的整个工作流程,并特别强调了洞穴的3D建模及其在VR环境中的集成。
