摘　　要：介绍了一种利用数字图像处理技术检测垂直管道中泡状流参数的新方法 ,其中利用差影算法来消除背景噪声 ,利用迭代法对图像进行最佳阈值分割。实验结果表明 。A new method has been developed to measure flowing parameters in a pipe. The method is based on digital image processing techniques, in which an image subtracted algorithm is used to remove the background noise and an iteration algorithm is used to calculate the optimizing threshold.Experimental results show that the method has the capacity of on line measuring of bubble sizes and gas area fraction in gas liquid two phase flow.
