基于图像的植物叶面雾滴接触角稳定区间法测量(Stable Interval Method Based on Images to Measure Drop Contact Angles on Plant Leaf Surfaces)
雾滴 叶面 接触角
2009/8/11
发展了单侧液滴轮廓拟合生成接触角的方法,提出了接触角稳定区间概念,建立了拟合函数选优和拟合像素数选取的数值试验方法。本文方法与轴对称积分法相比,偏差为1.92%。但本文方法没有引入轴对称条件,因而可测非对称液滴接触角。对桂花叶上去离子水滴接触角的测量研究表明:可用三阶多项式在像素数区间[110,160]上拟合生成接触角;主叶脉方向和与之垂直的方向之间接触角差异明显,均值相差7.15°,同一方向上左...
