<p style="text-indent:2em">The wheel-rail attitude of high-speed rail reflects the complex dynamic interaction and restraint relationship between wheels and rails. Mastering the true contact attitude between them is an important foundation for ensuring the safe of high-speed railways. How to accurately obtain the wheel-track attitude of high-speed railways has always been a hot research field in domestic railway scientific research. However, it is imprecise and unreliable to obtain the wheel-rail contact attitude from 2D image. Extracting the feature points of the wheel-rail surface and reconstructing a 3D model can obtain the wheel-rail contact attitude more realistically and accurately.
Due to the fast running speed of high-speed trains, the wheel-rail surface is relatively smooth and there are no obvious feature points, which brings great challenges to the 3D reconstruction based on feature point extraction.

高铁轮轨姿态反映了车轮与钢轨之间复杂的动态相互作用和约束关系，掌握他们之间真实接触姿态是保障高速铁路安全运营的重要基础。如何能够精确获得高铁轮轨姿态一直是国内铁路科研的热门研究领域。但单单从二维图像上获取轮轨接触姿态是不精确、不可靠的，而将轮轨表面的特征点提取出来，重建出一个三维模型能更加真实、准确地获得轮轨接触姿态。
由于高铁列车运行速度快，轮轨表面相对光滑且无明显特征点，给基于特征点提取的三维重建带来了极大挑战。
