To detect corona and find out the location of discharge of high voltage transmission line,a dual-spectrum fusion corona detection system based on DM8148 was designed,which realized dual-way video capture,processing,compression and storage.Timerecursive filtering algorithm is used to process solar blind ultraviolet image noise while multiresolution analysis algorithm is used to make solar blind ultraviolet and visible image fusion.Experimental results show that this method can improve the image visual effect and can fuse the available details together from ultraviolet and visible detect image effectively.
