Researchers have introduced HyDRA, a novel training-free framework designed to improve collaborative perception among heterogeneous agents. This architecture addresses the challenge of differing feature representations by employing a lightweight domain classifier to adaptively select fusion strategies. HyDRA routes homogeneous agents through intermediate fusion for maximum information gain, while heterogeneous agents are directed to late fusion to prevent data contamination. The framework also integrates anchor-guided pose graph optimization to reduce localization errors associated with late fusion. Experiments demonstrate that HyDRA achieves state-of-the-art performance under architectural heterogeneity and significantly enhances overall [email protected] compared to late fusion when latent domain heterogeneity is present.
