摘要
根据红外热图像的特点，提出了两类成像报警信号的产生方法。一种是过热区的探测报警，另一类是运动目标的探测报警。该方法考虑了红外热图像的空间、时问相关性以及干扰的随机性、不相关性，因而降低了误报率。与其它方法相比，文中所提出的方法算法简单，易于硬件实现，抗干扰能力强，实时性好。
Methods of generation of alarm signal are proposed in this paper accoding to features of IR thermal image. Two types of alarm are over-thermal area detection and moving object detection. It takes account of spatial correlation and temporal correlation of thermal image and randomness of noise.Thus mis-alarming is reduced. As compared with other method provided detection method in this paper has many advantages: simple algorithm and hardware implementation, noise-insensitive, good real-time performance.
