摘　　要：电力设备的在线监测具有非常重要的意义。针对目前一般采用的电力设备监测仪器———红外热像仪,存在着结构复杂、功耗较大、价格昂贵、不能实现在线监测的问题,文章介绍了以黑白CCD传感器为核心的电力设备在线监测实验系统,并围绕近红外热图像因受物体低温影响,从而影响温度场计算精度的问题,详细阐述了应用基于拉普拉斯塔形分解的图像融合方法对近红外热图像进行处理。The on-line monitoring of power equipment is extremely important and the infrared thermal imaging instrument is commonly used for this purposes, But with the disadvantages of complicated structure, high power consumption and high price, the infrared thermal imaging instrument can not meet all requirements of on-line monitoring and supervision. In this paper, a trail system of nearinfrared thermal imaging on-line monitoring for power equipment based on monochrome CCD sensor is introduced. Since the accuracy of the temperature field of near-infrared thermal image will be affected by the low temperature of object, the image processing method based on image fusion technique is elaborated.
