Design of Dual-spectrum Corona Detection System Based on DM8148

摘要:

针对高压输电线路电晕检测及定位问题,设计了基于DM8148的双谱段视频融合电晕检测系统,实现了双路视频的采集、处理、融合、压缩和存储.采用时域递归滤波算法对日盲紫外图像进行去噪处理,利用基于小波变换自适应加权融合法将日盲紫外、可见光两路视频进行实时融合.实验结果表明融合图像具有较好的视觉效果,能够很好地将紫外、可见光检测图像融合,实现电晕放电点检测的准确定位,系统能满足电晕检测的需求.

Abstract:

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.Time-recursive filtering algorithm is used to process solar blind ultraviolet image noise while multi-resolution 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.
