Ray-Aware Pointer Memory with Adaptive Updates for Streaming 3D Reconstruction

Chi Zhang, Feifei Li, Qi Song, Rui Huang

Ray-aware pointers that store both 3D position and viewing direction enable selective retain-or-replace updates for stable streaming 3D reconstruction.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Extensive experiments demonstrate that the proposed ray-aware memory design significantly improves long-term reconstruction stability and camera pose accuracy while maintaining efficient streaming inference.

C2weakest assumption

The assumption that joint reasoning over spatial distance and ray-direction discrepancy can accurately distinguish between local redundancy, novel observations, and potential loop revisits without additional mechanisms.

C3one line summary

Ray-aware pointer memory with adaptive retain-or-replace updates enhances stability and accuracy in streaming 3D reconstruction.
