摘　　要：研究了运动恢复结构(SFM)的基础理论,提出了基于双图像SFM算法的沥青路面构造模型三维重建方法,并对路面构造模型进行了重建,通过三维模型构造深度与沥青离析混合料的相关性研究得出沥青混合料离析的评价标准。首先应用体积法对双图像SFM重建的路面纹理模型进行分析研究,并计算了路面构造深度。使用铺砂法对测定区域进行检测,将铺砂法检测结果拟定为真实值与双图像SFM检测结果进行对比分析,验证了双图像SFM沥青路面构造深度检测方法的可行性与精度。最后基于沥青表面构造深度评价标准定义三维模型构造深度离析评价标准,通过对两者相关性分析,提出基于三维模型构造深度的沥青混合料离析定量评价标准。This paper studies the movement recovery structure(SFM) theory, the basis of double image SFM algorithm is proposed based on 3 D reconstruction method of asphalt pavement structure model, and reconstruction of the pavement structure model, through the three-dimensional model structure depth and correlation study of asphalt mixture segregation of asphalt mixture segregation evaluation standard. Firstly, the pavement texture model reconstructed by dual image SFM is analyzed by volume method, and the pavement structure depth is calculated. The sand-paving method was used to detect the measured area, and the detection results of sand-paving method were drawn up as the real value and compared with the detection results of dual-image SFM, which verified the feasibility and accuracy of the detection method of dual-image SFM structure depth of asphalt pavement. Finally, based on the evaluation standard of asphalt surface structure depth, the evaluation standard of 3 D model construction depth segregation was defined. By analyzing the correlation between the two, the quantitative evaluation standard of asphalt mixture segregation based on 3 D model construction depth was proposed.
