A Low-Latency 3D Live Remote Visualization System for Tourist Sites Integrating Dynamic and Pre-captured Static Point Clouds
中文摘要#
各種用於捕捉和傳輸動態三維空間的即時方法已被提出，包括基於 RGB-D 相機和體積捕捉的方法。 然而，將現有方法應用於戶外旅遊景點仍然困難，因為維護和美學限制限制了傳感器的放置，而日光變化使處理變得複雜。 我們提出了一種結合多個 LiDAR 和攝像頭的系統，用於即時動態點雲捕捉，並將其與預先捕獲的靜態點雲集成，以實現大範圍的三維可視化。 該系統在大範圍場景中保持 30 fps 的幀率，同時保持延遲低於 100 ms。為了緩解光照不一致的問題，靜態點雲顏色會自動調整為當前光照條件。 我們的系統的有效性通過在旅遊景點的實際部署得到驗證。
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.
