针对突发场景下的3D重建,提出抗干扰资源调度新方法。

Reliable Multi-view 3D Reconstruction for `Just-in-time' Edge Environments

  • 基于投资组合理论设计动态相机选择策略
  • 在时空相关中断下仍保障重建质量达标
  • 适合应急响应等对可靠性要求高的边缘场景

多视角3D重建正革新紧急救援、战术应用和公共安全等需快速态势感知的场景。由于近实时延迟需求与临时计算资源调配,常需在任务期间即兴部署边缘环境。然而此类环境固有的动态性与运行风险可能导致相机操作出现时空相关性中断,持续降低重建质量。本文提出一种受投资组合理论启发的边缘资源管理策略,可在相机面临时空相关中断时,仍保证3D重建质量满足要求。通过遗传算法求解组合优化问题,该方法在真实系统设置下收敛迅速。利用公开及自定义3D数据集验证,相比传统基线策略,在时空中断条件下显著提升重建可靠性。

原文摘要 · Abstract (English)

Multi-view 3D reconstruction applications are revolutionizing critical use cases that require rapid situational-awareness, such as emergency response, tactical scenarios, and public safety. In many cases, their near-real-time latency requirements and ad-hoc needs for compute resources necessitate adoption of `Just-in-time' edge environments where the system is set up on the fly to support the applications during the mission lifetime. However, reliability issues can arise from the inherent dynamism and operational adversities of such edge environments, resulting in spatiotemporally correlated disruptions that impact the camera operations, which can lead to sustained degradation of reconstruction quality. In this paper, we propose a novel portfolio theory inspired edge resource management strategy for reliable multi-view 3D reconstruction against possible system disruptions. Our proposed methodology can guarantee reconstruction quality satisfaction even when the cameras are prone to spatiotemporally correlated disruptions. The portfolio theoretic optimization problem is solved using a genetic algorithm that converges quickly for realistic system settings. Using publicly available and customized 3D datasets, we demonstrate the proposed camera selection strategy's benefits in guaranteeing reliable 3D reconstruction against traditional baseline strategies, under spatiotemporal disruptions.
