摘要
分析了粘连气泡的分割对PIV技术的重要性,提出了气泡分割的具体步骤,首先对粘连气泡图像进行二值化特征提取、区域填充、图像相减得到气泡亮点,随后通过对图像亮点的加厚得到粘连气泡的分割线,从而得到气泡的像面尺寸.将其与水线分割法相对比,证明了该方法的适时性.
The importance of image segmentation of conglutinative bubbles to PIV technique is analyzed. Material process of division bubbles is put forwards. First,through two-value character distill,area fill,image minus to bubbles image,the bubbles brightness dots are obtained. Later,through adding thick to image brightness dots, the division of conglutinative bubbles is obtained. Based on that, the bubbles picture size can be gained. Compared with the waterline image segmentation,this method is more timing.
