摘　　要：电气部件是电力传输与控制的关键部件,其运行状态直接影响到整个系统的安全状态和运行效率。老化、短路、断路和非正常运行等是电气部件事故的原因或表现形式。红外热成像检测能够有效判断电气部件的运行状态,但通常的人工比对方法存在效率低、错误率高等问题。基于图像特征提取和比对技术,本文提出一种半自动的图像比对分析方法,能够有效提高红外热成像检测的效率。Electrical equipment is key component for power transmission and control, its running situation could do harm to the safety and efficiency of the whole system. Aging, short circuit, breaker contact and undesirable running state will affect the electrical equipment. Infrared thermograph monitoring can effectively find the running status of electric equipment, but with slow speed and high error rate while comparing the image results artificially. This paper proposes a semi-automatic image comparison analysis method, based on image feature extraction technology, which effectively improves the efficiency of the infrared thermograph monitoring.
