However, many existing methods (i) fuse modalities before sufficiently enhancing intra-modal semantics and (ii) are sensitive to modality discrepancies caused by heterogeneous sensor characteristics. To address these issues, we propose PACNet (Pyramid Attention Collaboration Network), a hierarchical RGB-T framework that jointly models multi-scale and global context and performs refinement-before-fusion with cross-modal collaboration. Specifically, Dense Atrous Spatial Pyramid Pooling (DASPP) captures multi-scale contextual cues across semantic stages, while Multi-Head Self-Attention (MHSA) establishes long-range dependencies for global context modeling. We further design a hierarchical feature integration scheme that constructs two complementary feature streams, preserving fine-grained spatial details and strengthening high-level semantics. These streams are refined using a cross-interactive dual-attention module that enables bidirectional interaction between spatial and channel attention, improving localization and semantic discrimination while mitigating modality imbalance. Experiments on three public benchmarks (VT821, VT1000, and VT5000) demonstrate that PACNet achieves state-of-the-art performance and delivers consistent gains in challenging conditions such as low illumination, thermal clutter, and multi-scale targets.
