EAST冷质磁体位移测量与分析

Design and analyze of the displacement for cold qualitative magnet in EAST

为了测量EAST磁体位移的变化,采用计算机视觉处理方法构筑三维测量模型,利用边缘检测算法对图像采集系统获得的图片进行识别和检测,最终得出位移的变化值,从而可以在等离子体磁场位形控制中通过补偿修正这些变化。该测量方法解决了EAST装置冷质磁体位移测量的难题。

In order to measure the displacement, computer vision processing method was used to build the three-dimensional measurement model, the pictures were distinguished and detected by the image acquisition system, and then the displacement data was got. The displacement measure problem of cold qualitative magnets of EAST was solved.
