A Low-Latency 3D Live Remote Visualization System for Tourist Sites Integrating Dynamic and Pre-captured Static Point Clouds
中文摘要#
各种用于捕捉和传输动态三维空间的实时方法已被提出，包括基于 RGB-D 相机和体积捕捉的方法。 然而，将现有方法应用于户外旅游景点仍然困难，因为维护和美学限制限制了传感器的放置，而日光变化使处理变得复杂。 我们提出了一种结合多个 LiDAR 和摄像头的系统，用于实时动态点云捕捉，并将其与预先捕捉的静态点云集成，以实现大范围的三维可视化。 该系统在大范围场景中保持 30 fps 的帧率，同时保持延迟低于 100 ms。为了缓解光照不一致的问题，静态点云颜色会自动调整为当前光照条件。 我们的系统的有效性通过在旅游景点的实际部署得到验证。
英文摘要#
Various real-time methods for capturing and transmitting dynamic 3D spaces have been proposed, including those based on RGB-D cameras and volumetric capture. However, applying existing methods to outdoor tourist sites remains difficult because maintenance and aesthetic constraints limit sensor placement, and daylight variability complicates processing. We propose a system that combines multiple LiDARs and cameras for live dynamic point cloud capture, and integrates them with pre-captured static point clouds for wide-area 3D visualization. The system sustains 30 fps across wide-area scenes while keeping latency below 100 ms. To mitigate lighting inconsistencies, static point-cloud colors are automatically adjusted to current lighting. The effectiveness of our system is demonstrated through real-world deployment in a tourist site.
