Abstract: 隨著虛擬實境(VR)與沉浸式媒體的發展,如何有效重建具真實感的人物動作場景,成為影像處理與互動內容設計中的重要課題。現有動態人像捕捉系統雖可產出高品質結果,卻多仰賴昂貴設備與複雜後製流程,應用門檻高。近年新興之高斯潑灑(Gaussian Splatting)技術,提供實現動態人像重建的低成本替代方案。
本研究提出一套基於四維高斯潑灑(4D Gaussian Splatting)之人物動作重建與處理流程。針對說書演講、太極拳教學等以人物為主之表演,先進行多視角同步拍攝,並以 Background Matting V2 擷取每影格前景,保留人物、椅子與道具等作為重建目標。為解決 V^3 原始方法於 3D 重建階段可能殘留背景色點雲之問題,本研究設計一套基於背景顏色的高斯點過濾機制,以去除非目標高斯點並保留動作連貫性。最終,重建成果整合至 Unity 並部署於 Meta Quest 3 平台,支援使用者於 VR 環境中自由視角觀看表演內容。
With the growth of virtual reality (VR) and immersive media, reconstructing realistic human-centric motion has become an important challenge. Gaussian Splatting offers a lightweight alternative for dynamic reconstruction.
This study proposes a pipeline based on 4D Gaussian Splatting for scenes such as storytelling or Tai Chi. Multi-view videos are processed with Background Matting V2 to extract foreground elements. To address the issue of background-colored splats in the original V^3 method, we introduce a color-based filtering strategy to enhance foreground clarity and motion consistency. Finally, the reconstructed results are integrated into Unity and deployed on Meta Quest 3, enabling free-viewpoint playback in VR.
