| 摘 要： | 在研究自相似理论的基础上，以常见SMA－13、AC－13和LSAM3种沥青路面的二维数字图像为研究对象，基于单幅图像的重构技术进行沥青路面表面形貌三维重构，获得沥青路面表面形貌数据信息，并利用SELFIS工具中的Whittle最大似然估计法对其进行自相似性研究。研究结果表明：3种沥青路面表面形貌具有高度的自相似性，为建立沥青路面表面形貌三维仿真模型奠定了基础。

| Abstract: | Based on the self-similarity theory, the self-similarity of asphalt pavement surface topography is discussed, taking the digital images of SMA-13, AC-13 and LSAM asphalt pavement as example. To obtain the asphalt pavement surface topography data, the three-dimensional reconstruction is made based on single image data and then the self-similarity is studied by the method of Whittle maximum likelihood estimation in the SELFIS tool. The results show that the SMA-13 asphalt pavement surface topography is high in self-similarity, which lays a foundation for the establishment of three-dimensional simulation model of asphalt pavement surface topography. |
