基于视频叠加算法的变电站易损高压电气设备可视化监控技术研究摘要：樵銮勘涞缯靖哐沟缙设备易损性可视化效果，研究了基于视频叠加算法的变电站高压电气设备易损性可视化监控。利用改进的α混合算法结合视频背景色的反走样，叠加可见光视频以及红外视频，选取引导滤波器将视频帧分为基础层和细节层，利用改进的自适应加权二维主成分分析（W2DPCA）融合基础层，选取细节层作为最终细节层，获取最终融合帧，实现变电站高压电气设备易损性可视化监控。实验结果表明，采用该方法所获取监控画面可体现丰富的变电站高压电气设备细节，纹理色彩以及设备边缘对比度有所强化，便于准确判断变电站高压电气设备易损性。关键词：视频叠加算法;变电站;高压;电气设备;易损性;可视化监控：TM63文献标识码：AVisualSupervisionofVulnerableHighvoltageElectricalEquipmentinSubstationBasedonVideoOverlayAlgorithmFUZhanwei（InnerMongoliaEHVPowerSupplyBureau，Hohhot，InnerMongolia010080，China）Abstract：Inordertoenhancethevisualeffectofvulnerabilityofhighvoltageelectricalequipmentinsubstation，visualmonitoringofvulnerabilityofhighvoltageelectricalequipmentinsubstationbasedonvideosuperpositionalgorithmisstudied.Using第1页共2页improvedαthehybridalgorithmcombinestheantialiasingofvideobackgroundcolor，superimposesvisiblevideoandinfraredvideo，selectsthepilotfiltertodividethevideoframeintothebaselayerandthedetaillayer，usestheimprovedadaptiveweightedtwodimensionalprincipalcomponentanalysis（W2DPCA）tofusethebaselayer，andselectsthedetaillayerasthefinaldetaillayertoobtainthefinalfusionframe，Visualmonitoringofvulnerabilityofhighvoltageelectricalequipmentinsubstationisrealized.Theexperimentalresultsshowthatthemonitoringimagesobtainedbythismethodcanreflectrichdetailsofsubstationhighvoltageelectricalequipment，andthetexturecolorandedgecontrastofequipmentareenhanced，whichisconvenienttoaccuratelyjudgethevulnerabilityofsubstationhighvoltageelectricalequipment.第2页共2页
