근적외선 이미지 기반 화재 현장 연기 투시 및 열화상 융합 효과에 관한 연구

초록

Dense smoke generated in fire and disaster scenes critically impairs visibility, hindering both rescue operations and situational assessment. This study experimentally investigates a smoke-penetration technique using near-infrared (NIR) illumination and infrared cameras, and proposes an approach to enhance visual information by integrating thermal imaging. Illumination sources with wavelengths of 720 nm, 850 nm, and 950 nm were used to evaluate object visibility in smoky environments, and 850 nm was selected as the optimal wavelength based on performance. Additionally, thermal imaging of the same scenes was conducted to analyze the effectiveness of multimodal image fusion. The results show that longer wavelengths exhibit greater resistance to smoke scattering, thereby improving object detection. Furthermore, fusion with thermal imaging enabled simultaneous acquisition of structural and thermal characteristics. These findings suggest that the integration of NIR and thermal imaging technologies can serve as a core component of smoke-penetrating camera systems, providing a practical technological foundation for future disaster response and rescue operations.
