MATLAB 在 SBS 改性沥青粒度分布特性研究中的应用

摘要

Styrene-butadiene-styrene three block co-polymer modified asphalt fluorescence microscopic image as the research object, SBS modi-fied asphalt fluorescence microscopic images were pre-processed by MATLAB image reading, image conversion, noise reduction, image enhance-ment, image segmentation and other digital image technology to get binary images. Then particle size parameters were extracted from them. Finally, multi-parameters fitting analysis was conducted to determine the optimal model of particle size distribution curve.%以苯乙烯-丁二烯-苯乙烯三嵌段共聚物改性沥青荧光显微图像为研究对象，采用MATLAB图像读取、图像转化、图像降噪、图像增强、图像分割等数字图像处理技术对SBS改性沥青荧光显微图像进行前处理，得到二值图像并在此基础上提取其粒度参数，并对目标图像的粒度分布曲线进行多参数模型拟合分析，得到了粒度分度最优模型。
