摘　　要：输电线路智能视频监控系统是由嵌入式视频装置、通信通道、后台存储服务器等部分组成,嵌入式视频装置在现场拍摄视频和图像后,现场通过色度提取、基于小波的Canny边缘检测、轨迹追踪、向量机分类等图像识别和模式识别方法,自动识别出架空输电线路本体及周边环境变化产生的风险因素,如导线弧垂变化、大型机械入侵施工、鸟巢活动、飘挂物等,然后产生报警信息后发回服务器,节约了通信费用.经过3年的实际运行经验表明,此系统为佛山地区输电线路防外力破坏发挥了巨大作用,具备广阔的推广应用情景.Transmission line intelligent video surveillance system is embedded video device, communication channel, the background storage server three components, embedded video device at the scene after the shooting video and images, directly on-site by chroma extraction, wavelet-based Canny edge detection tracking, vector machine classification, image recognition and pattern recognition methods, automatic identification of risk factors generated by overhead transmission line of the body and the surrounding environment, such as wire sag change, invasion of large-scale machinery construction, Bird＇s Nest, Gone with the Wind hanging like and then generate alarm information back to the server, saving communication costs. After three years of actual operating experience indicate that this system for the transmission line against external damage play a huge role, with broad application scenario.
