从稀疏航拍点云生成实时高精度地面视觉场景
Generating real-time detailed ground visualisations from sparse aerial point clouds
- 基于稀疏航拍点云，自动扩增真实扫描数据
- 支持实时渲染，可近距交互查看细节
- 适合训练、仿真、游戏与可视化应用
在步行视角或车载视角下观察的大型室外3D内容，通常需要大量专业艺术家团队进行建模、贴图、材质着色和光照处理，导致成本高昂且难以准确还原真实地表多样性。本文提出一种新方法，通过自动扩增真实扫描数据，实现高保真度的实时动态3D渲染，支持近距离探索，适用于训练、仿真、视频游戏及可视化等场景。
原文摘要 · Abstract (English)
Building realistic wide scale outdoor 3D content with sufficient visual quality to observe at walking eye level or from driven vehicles is often carried out by large teams of artists skilled in modelling, texturing, material shading and lighting, which typically leads to both prohibitive costs and reduced accuracy honoring the variety of real world ground truth landscapes. In our proposed method, we define a process to automatically amplify real-world scanned data and render real-time in animated 3D to explore at close range with high quality for training, simulation, video game and visualisation applications.
