基于图像处理的油圈分布特性研究

油圈在日常生活中经常可见．然而，油圈的分布特性迄今为止尚未得到深入研究．本文采用数字图像处理的方法来研究油圈的分布特性，具有直观、简便的优点．采用数码相机对油圈进行拍照，利用图像处理技术对图片进行图像相减、二值化、连通分量提取等处理，即可得到油圈的尺寸、数目等信息．采用直方图、高斯拟合等方法对上述信息进行一定的处理可得到油圈的分布特性．研究结果表明，经过搅拌处理后，直径大的油圈数目较少，直径小的油圈数目较多，且油圈数目与直径之间近似满足高斯分布规律．

Research on Oil Ring Distribution Characteristics Based on Image Processing

Oil rings are universal in daily life. How been studied so far. We study the oil ring distribut method, which is intuitive and convenient. Using a ever,the distribution characteristics of ion characteristics based on the digita digital camera to get the photos of the oil rings have not 1 image processing oil rings, then ap- plying image processing technology such as image subtraction, binarization and connected components extrac- tion to analyze the image, the information of oil rings such as size and number can be obtained. By means of histogram and Gaussian fitting to deal with the above information, the distribution characteristics of the oil rings can be obtained. The results show that, after stirring processing, the larger the diameter is, the smaller the number is. Moreover, the number and diameter of the oil rings approximately accord with Gaussian distri- bution.
