摘要
智能视频监控领域中普遍使用红外热成像技术以提高监控效果。红外热成像技术的依据是,自然界一切温度高于绝对零度的物体,每时每刻都在反射载有物体特征信息的红外线,由此研发出一种被动红外夜视技术。利用红外热成像技术可提高铁路安全防护系统的可靠性和效率。重点就红外热成像技术特点、基于红外热成像技术的视频监控系统架构及其报警方式,以及红外热成像技术在铁路安全防护中的应用等方面进行分析探讨。
Infrared thermal imaging technology is widely applied in the field of intelligent video surveillance to improve image quality. As any object with temperature higher than absolute zero in the natural world reflects infrared rays that carry the characteristic of the object at all time, a passive infrared technology of night vision is developed. The application of infrared thermal imaging technology contributes to the improvement of reliability and efficiency of railway safety and protection system. The paper focuses on the technological characteristics and builds the analysis and discussion on the video surveillance framework and the alarm approaches of this technology as well as its application to railway safety and protection.
