摘要
基于数字图像处理的原理,提出用八连通判别算法对大气PM 2.5显微图像的二值图像进行标记颗粒和测量颗粒粒径的大小;并在VC++6.0实现了标记和测量颗粒的算法,统计颗粒的尺寸分布。结果表明,这种颗粒标记和粒径测量的方法不受颗粒形状的影响,适用于大气PM 2.5颗粒物的测量。
Based on digital image processing, the arithmetic of 8-connected regions is put forward order to mark the particle and measure its diameter in the micrograph of PM2. 5. Moreover, the particle is marked and measured based on Visual C＋＋6. 0. The results show that the arithmetic can work. This method is not affected by the particle figure.
