本工作采用快速CCD相机采集并保存托卡马克等离子体放电时的图像。根据放电时等离子体图像的位置特点，采用改进的主动轮廓模型算法实时获得等离子体边界位置，并通过最小二乘法对其边界进行拟合，以此获得等离子体的中心位置，为进一步进行等离子体的实时控制提供了基础。该方法已成功应用于EAST装置的放电实验中，并取得了良好的效果。

A fast CCD camera image acquisition system for EAST was introduced in this paper .According to the characteristics of plasma image position during the plasma discharge ,an improved active contour model algorithm was proposed in real-time plasma boundary detection .By using least squares method to fit the edge of plasma ,the center and the radius of the plasma edge were obtained .It has considerably practical meaning for further control of plasma .The experiment results during EAST discharge show that the method presented in this paper can realize the expected goals and produce almost perfect effect .
