沥青混合料数字图像处理技术的方法研究

Study on Asphalt Mixture Digital Image Processing

本文重点研究了采用数字图像处理技术评价沥青混合料组成结构的可行性,根据混合料的自身特点探索了有效的图像处理技术,包括沥青混合料图像的获取、初步分析、增强处理、颗粒分析等技术,在此基础上提出利用参数颗粒主轴方向评价压实后的混合料结构稳定状态,试验结果表明效果良好。

In this paper,the technique of using digital image processing to evaluate asphalt mixture component structure was mainly introduced.According to the characteristics of asphalt mixtures,an effective method of image processing was explored,including the techniques of digital image acquiring,initial analyzing,enhanced processing,and particle analyzing,etc.Thus,the factor of the direction of particle principal axis was developed to evaluate the stability of the mixture structure.The results are reasonable.
