• Industry 应用 Landscape

1.1 Autonomous Driving Simulation

Maturity: Engineering | Players: AISim, Li Auto mindVLA, NVIDIA DRIVE Sim

流水线: Real-world 扫描 (LiDAR + multi-camera) → 3DGS reconstruction → Sensor simulation → HIL/SIL 测试

Key papers: GSDrive, GS-Playground (10^4 FPS, RSS 2026), GS-Surrogate, FieryGS, Nighttime AD GS, Real2Sim (4DGS + differentiable MPM), GS-SCNet, Ground4D, ULF-Loc (CVPR 2026 highlight)

质量 bar: Sensor sim error < 0.02, LiDAR > 30 FPS, LPIPS < 0.1, Radar ±3 dB

Notes: LiDAR sim requires opaque surface Gaussians; OpenDRIVE co-registration mandatory; nighttime needs separate IR-adjacent trAIning

1.2 Digital Twin & Smart City

Maturity: Commercial | Players: SuperMap, FantoVision, LCC

流水线: Aerial + streetview → Large-扩展 3DGS → S3M conversion → GIS integration → IoT fusion

Key papers: DiffSoup, Street Gaussians, GlobalSplat, Large-扩展 HQ Head

Standards: S3M (Chinese GIS), OGC 3D Tiles, glTF/glb, CityGML

Notes: City-level = 10^9–10^10 Gaussians; WGS84→ENU→3DGS alignment critical; 流ing LOD mandatory; S3M needs custom 导出er

1.3 Cultural Heritage & Museum

Maturity: Commercial

流水线: Controlled-lighting photography → High-fidelity 3DGS → Color calibration → Digital 归档 → VR/AR exhibition

质量: Sub-mm geometry, ΔE < 2 (CIE76), 2048×2048+ texture, lossless 压缩ion

Notes: Dome/array lighting > flash; attach DOI/cata记录 metadata; store raw images + COLMAP + 检查point + 压缩ed .ply

1.4 Film & Game Production

Maturity: Exploration | Players: Volcengine, UE team, Tencent

流水线: Multi-camera capture → 3DGS → Mesh 提取ion (SuGaR/2DGS) → UE5 导入 → Virtual production

Notes: 3DGS→mesh needed for DCC; SuGaR (TSDF) > nAIve marching cubes; material separation (GOR-IS/SSD-GS) for relighting; 4DGS (GauFRe/DeformGS) for temporal consistency; UE5 Nanite+Lumen experimental

1.5 E-commerce 3D Display

Maturity: Commercial

流水线: Turntable photography → 3DGS → 压缩ion (移动GS/获取A-3DGS) → 网页 AR preview

Requirements: < 50 MB, browser-renderable (网页GPU/网页GL2 via gsplat.js), < 5s load on 4G

Notes: 50x+ 压缩ion needed for 网页; mesh fallback for low-end; AR needs mesh (Quick Look/Scene Viewer)

1.6 Industrial Inspection

Maturity: Engineering

流水线: Drone capture → 3DGS → AI defect 检测ion → Measurement → 报告

Key papers: EnerGS (LiDAR-3DGS fusion), RGS (CBCT inspection), E2EGS (end-to-end field)

Notes: GPS geotagging for defect correlation; EnerGS for LiDAR+cam fusion; 检测 ≥ 5mm at 10m; CAAC/FAA 合规

1.7 AR/VR/MR

Maturity: Exploration

流水线: Real-time head设置 扫描 → 3DGS → 6DoF 追踪ing + low-latency render → MR overlay
