Power Transmission Corridors Wildfire Detection for Multi-Scale Fusion and Adaptive Texture Learning Based on Transformers

Ensuring the operational safety of power transmission corridors is critical for maintaining a stable electricity supply. However, their geospatial complexity makes them increasingly vulnerable to wildfires. Wildfires vary dramatically in scale—from pixel-level ignition to kilometer-wide spread—and often occur in visually cluttered environments. These conditions challenge existing Transformer- andYOLO-based detectors, which struggle with multi-scale feature conflicts and fine-grained inter-class distinctions. To address this, we propose a unified wildfire detection framework incorporating two key modules: the Multi-scale Adaptive Texture Encoding (MATE) module and the Dynamic Feature Pyramid Integration (DFPI) module. MATE leverages heterogeneous receptive fields to capture wildfire patterns across spatial scales, while DFPI enhances feature discrimination via scale-aware attention and adaptive resolution fusion. Additionally, we construct a large-scale wildfire dataset with 5,000 annotated images covering diverse terrains, weather, lighting, and fire stages. Extensive experiments show that our method outperforms state-of-the-art baselines in detecting wildfires under real-world, cluttered conditions.
