LR-V2X: Loss-Resilient Collaborative Perception under Low-Bandwidth Communication

Read the original on arXiv Computer Vision →

LR‑V2X is a loss‑resilient collaborative perception framework for vehicular networks that reconstructs missing bird‑view (BEV) features from corrupted latent representations, even under severe packet loss. It converts corrupted latents into a spatial prior and uses ego‑vehicle context to recover BEV information, requiring only training under full‑communication conditions. Experiments on DAIR‑V2X and V2XREAL demonstrate that LR‑V2X maintains robust collaboration while reducing communication overhead by 64× compared to dense BEV fusion methods.

Dense Coverage, Sparse Refinement: Byte-Constrained Cooperative Perception

The paper introduces a byte‑constrained cooperative perception framework that balances dense coverage with sparse refinement. Each vehicle sends a highly compressed coarse Bird’s‑Eye‑View (BEV) layer covering the entire map and uses the remaining bandwidth to transmit high‑resolution patches selected by a Task‑Aware Benefit Selector. Experiments on DAIR‑V2X and OPV2V demonstrate that this coverage‑refinement strategy achieves superior accuracy‑payload trade‑offs, reaching 0.60 AP@0.7 with only 1.87 KB per non‑ego agent.

HMS-SCP: Task-Oriented Multi-Scale Semantic Communication for V2X Cooperative Perception

The paper introduces HMS‑SCP, a hierarchical multi‑scale semantic‑aware cooperative perception framework for V2X communication. It uses a spatial importance predictor to select task‑relevant grid elements at multiple scales and maps them directly into complex‑valued symbols for joint source‑channel coding, achieving ultra‑low symbol rates and noise resilience. Experiments on OPV2V and DAIR‑V2X show that HMS‑SCP maintains high‑confidence far‑field detection with sub‑16 ms latency even under severe Rayleigh fading and extreme compression.
