融合显示红外在线监测系统的研究

图像融合是信息融合领域的一个热点．图像融合的目的是把来自多传感器数据的互补信息合并，形成一幅新的图像，以便更好地增强监视和侦察之类的视觉感知．红外在线监测以远距离、非接触、实时、快速等方式获取设备的运行状态信息，进而及时地排除故障．本文提出了基于融合显示的红外在线监测系统组成方案，描述了图像融合的基本概念、层次以及应用价值；其次，通过分析红外图像与可见光图像融合的特点，并据此给出本实验融合方法的选择原则；最后，讨论了基于小波变换实现图像融合的原理并给出红外热像和可见光图像的融合效果；通过模拟实验，证明了图像融合技术在热故障的准确定位上有很高的实用价值。

A research of fusing display infrared online monitoring systerm

The image fusion is one of research hotspots in data fusion field, The purpose of image fusion is to merge comple- mentary information from multisensor data for visual perception, such as surveillance and reconnaissance. As a removed non- contaet real-time technique,infrared online monitoring obtains the status messages of equipment rapidly, so that we can repair it in time, In this paper,the composing seheme of this monitor system is presented. The basle concept, fusion hierarchy and applying value are depleted in this paper. Then,according to the analysis of infrared and visible image fusing characteristic, the selecting reason of image fusing method in this experiment are given out, At last, the image fusion principle based on the wavelet transform is introduced and the fused images with infrared and visible image are displayed. The result of this simulation experiment shows that the image fusion has a significant practical value in improving the accuracy of locating faults.
