摘　　要：本文采用快速CCD相机采集托卡马克装置的等离子体放电图像,根据等离子体放电的位置特点,采用基于Otsu阙值改良的Canny算法对等离子体图像进行等离子体边界位置的提取,并通过最小二乘法进行边界拟合,从而得到准确的等离子体位置。In this paper,a fast CCD camera was used to capture the Tokamak plasma discharge image.According to the characteristics of plasma image position during the plasma discharge,an improved Canny algorithm to extract the real plasma boundary position based on Otsu threshold was proposed in plasma boundary detection.By using least square method to fit the boundary of plasma image,the accurate position of plasma was obtained.
