由于红外成像具有被动工作、抗干扰性强、目标识别能力强、全天候工作等特点,红外检测诊断技术应运而生。已被多数发达国家用于军事、工业等各行各业。图像拼接是把两幅有重叠的图像叠加成一幅大尺度图像的过程。文中介绍了图像拼接技术的几种基本方法和发展历程,并针对电力系统红外诊断技术,结合红外在线检测的特点,应用相位相关方法对红外图像进行无缝拼接,使得诊断结果更精确、更有说服力,并且实验说明了方法的可行性和有效性。
Because of passive work, strong anti-jamming and target recognition ability, around the clock in infrared imaging and so on,in- frared detection and diagnosis technology came into being. Most developed countries have been used for military,industrial and other in- dustries. Image mosaic is proeesging two or more overlapping image to a large scale image. It introduces several methods and development processing of image mosaic technology,and aiming at infrared diagnostics technology of power system, combined with the characteristics of infrared on-line detection,use phase correlation method for seamless mosaicing of infrared image,which makes the diagnosis more accurate, more convincing, and the experiment illustrates the feasibility and effectiveness.
