城市地下空间已经成为全球发展最快的工程建设和商业运营市场，我国城市地下工程建设水平和规模也达到了世界先进水平，但随之而来的城市地下空间的安全事故也明显增加，而相应的安全监控和应急救援却严重滞后，本文针对我国城市地下空间防恐、防爆、防核生化袭击等安全保障问题，分析红外成像技术在地下空间防灾监测与应急搜救中面临的挑战，提出了短波红外成像、多尺度红外成像预处理、图像自适应增强、环境自适应红外成像、灾情定位及报警等关键技术及其系统应用，探讨了红外成像技术在地下空间灾场的应用,可为我国城市地下空间安全立法和战略规划的制定提供参考。

Urban underground space has become the fastest growing area in global engineering construction and commercial operation. The scale and level of China's urban underground engineering have reached considerably advanced, but ensuing security accidents in urban underground spaces have also significantly increased, and the necessary security monitoring and emergency rescue measures are seriously lacking. This paper focuses on the security issues pertaining to terrorism, explosions, and nuclear biological or chemical attacks in urban underground spaces and analyses the challenges faced by infrared imaging technology when implemented in disaster monitoring and emergency search and rescue. The key technologies and applications presented include shortwave infrared imaging, multi-scale infrared imaging preprocessing, adaptive image enhancement, adaptive infrared environment imaging, and disaster location and alarm. This paper discusses the applications of infrared imaging technology in underground space emergencies such as fires. The research presented here can provide references for security legislation and the strategic planning of urban underground space in China.
