**Beyond Dead Reckoning: A Point of View on Camera--DAS--GNSS Continuity in Road Tunnels**

针对道路隧道卫星不可见下的连续定位需求，提出相机-DAS-GNSS跨模态轨迹连续思路，并面向隧道定位连续性制定验证议程。

## 核心要点

- 道路隧道遮挡卫星，而网联自动车辆仍需连续、可归属且有完整性边界的定位。
- 方法将隧道定位视为基础设施辅助的跨模态轨迹连续，而非依赖最后可信卫星定位外推。
- 入口可信GNSS提供全局锚，DAS、相机、车载感知与边缘计算共同提供证据、关联、融合和监测。
- 文章提出可证伪的研究与部署议程，从同步多模态证据推进到完整性感知的隧道定位连续性。

**验证范围与局限**：验证范围指向道路隧道定位连续性；摘要未描述仿真或真机实验结果。

## 英文摘要 (Abstract)

Road tunnels remove satellite visibility where connected and automated vehicles still require continuous, attributable, and integrity-bounded positioning. This Point of View argues that tunnel localization should be treated as infrastructure-assisted cross-modal track continuity, not as extrapolation from the last trusted satellite fix. A trusted portal satellite solution provides the global anchor, distributed acoustic sensing (DAS) continuous motion evidence, cameras sparse identity and lane anchors, onboard sensing short-term dynamics, and edge computing association, fusion, integrity monitoring, and guarded reacquisition. Ground truth is reserved for offline calibration and validation. The article develops a falsifiable research and deployment agenda for progressing from synchronized multimodal evidence to validated, integrity-aware tunnel positioning continuity.
