By combining game engines with indoor mapping, it is possible to create interactive virtual environments that represent the real world. In this paper a virtual version of an audio installation in a historic building is produced, where the user freely explores the building and experiences a set of audio clips, creating a virtual radio play. A depth camera indoor mapping system, Matterport, captured a set of staged interiors. The aim was to evaluate the quality and usability of the indoor models and to demonstrate applying them in 3D application development. The quality of the models was evaluated by comparison with laser scanning, revealing limitations with Matterport: increasing the size of the measured area lowered the level of detail and accuracy of volumetric models. The quality of textures was not affected by this limitation, maintaining the appearance of models. To obtain optimised models for mobile 3D applications, a manual revision process was applied.

用于3D虚拟广播播放的深度摄像头室内映射

通过将游戏引擎与室内地图相结合,可以创建代表真实世界的交互式虚拟环境。在本文中,制作了一个历史建筑中音频设备的虚拟版本,用户可以在其中自由浏览建筑物并体验一组音频剪辑,从而创建虚拟广播。深度相机室内制图系统Matterport捕获了一组舞台内部。目的是评估室内模型的质量和可用性,并演示将其应用于3D应用程序开发中。通过与激光扫描进行比较来评估模型的质量,从而揭示了Matterport的局限性:增加测量区域的大小会降低体积模型的细节水平和准确性。纹理的质量不受此限制的影响,保持模型的外观。为了获得针对移动3D应用程序的优化模型,应用了手动修订过程。
