Beschreibung：增强现实（AR）体验通常在室内、建筑物内运行良好，在这些地方，通常照明条件稳定，环境规模小且固定，并且可以容易地放置标记。这不是户外AR体验的情况。在本文中，我们提出了实际的解决方案的AR应用程序，几乎恢复谢菲尔德的中世纪城堡的Castlegate区在谢菲尔德市中心，它曾经站在那里。该区域的简化3D模型与传感器融合一起用于支持用户对准过程和随后的方向跟踪。通过使用与太阳的定向照明匹配的定向照明、虚拟地平面和基于在对齐阶段中使用的相同模型的深度掩蔽来提高渲染真实性。根据需要，深度掩蔽确保城堡正确地位于真实的建筑物的前面或后面，从而解决遮挡问题。Unity游戏引擎用于开发，生成的应用程序在最近的高规格Android移动的手机上实时运行。
Beschreibung: Augmented Reality (AR) experiences generally function well indoors, inside buildings, where, typically, lighting conditions are stable, the scale of the environment is small and fixed, and markers can be easily placed. This is not the case for outdoor AR experiences. In this paper, we present practical solutions for an AR application that virtually restores Sheffield’s medieval castle to the Castlegate area in Sheffield city centre where it once stood. A simplified 3D model of the area, together with sensor fusion, is used to support a user alignment process and subsequent orientation tracking. Rendering realism is improved by using directional lighting matching that of the sun, a virtual ground plane and depth masking based on the same model used in the alignment stage. The depth masking ensures the castle sits correctly in front of or behind real buildings, as necessary, thus addressing the occlusion problem. The Unity game engine is used for development and the resulting app runs in real-time on recent high-spec Android mobile phones.
