HMS-SCP: Semantic-Aware Cooperative Perception for Safer Intelligent Transportation
The Hierarchical Multi-Scale Semantic-Aware Cooperative Perception (HMS-SCP) framework tackles the issues of bandwidth and safety in cooperative perception for intelligent transportation systems. This approach, outlined in a paper on arXiv (arXiv:2608.14603v1), emphasizes task-oriented semantic communication. Through Vehicle-to-Everything (V2X) communication, vehicles and infrastructure can share sensor data, which improves sensing coverage. Although late fusion is efficient in terms of bandwidth, intermediate fusion strikes a better balance between bandwidth and accuracy. In densely populated urban settings, bandwidth requirements may surpass network capabilities, endangering safety-critical Cooperative Intelligent Transport Systems (C-ITS) operations. HMS-SCP presents a noise-resilient and bandwidth-efficient solution that utilizes a spatial importance predictor for optimal communication resource distribution, enhancing real-world performance.
