图像处理在安全壳缺陷检测中的应用

Application of image processing in nuclear power plant containment surface defect detection

由一台轮式负压吸附型爬壁机器人携带一台高清摄像机和无线发射器在安全壳外柱面移动,安装在爬壁机器人上摄像机将拍摄的安全壳墙面视频信息经由无线发射器发送至位于地面的无线接收终端,无线接收终端再将视频信息传送至上位机。安装在上位机上的监控测量处理软件系统对接收到的图像进行分析处理和显示,并将存在缺陷的图像发送至缺陷测量模块进行缺陷信息测量,最终测量所得到的缺陷参数和对应图像会存入后台数据库进行存储管理,方便在线或离线浏览历史数据,监测安全壳外壁缺陷的动态变化情况。

A wheeled negative pressure adsorption climbing robot carrying a high definition camera and a far distance wireless transmitter moves smoothly on the nuclear power plant containment wall .When the robot moves on the containment wall ,the camera fixed on the robot sent the wall video information back to the receiver at the bottom of the containment wirelessly ,then the receiver transfers the video information to the local PC .The video will be analyzed , processed and displayed by the monitoring and measuring processing software system installed on the PC ,and then the image which contains defect information will be transferred to the defect measure module for defect measuring .Finally the defect information and the corresponding image will be stored into the backstage database .This is quite convenient for online and offline browsing to check and monitoring dynamic change of the containment defect .
