摘要： 根据阴影恢复形状原理，提出一种基于单张影像的快速月面三维建模和光照模拟方法。利用单张2D影像中残留的3D线索——灰度信息，通过SFS方法对月面三维形貌进行快速重建，采用改进的Hapke光照模型对重建后的三维形貌进行渲染。实验结果证明，在精度允许范围内，该方法能快速地实现对月面三维形貌的提取和仿真。

Abstract: A fast method of 3D reconstruction and illumination simulation of lunar surface based on single image is proposed, using Shape from Shading(SFS) method. By using the 3D clew, gray information of single 2D image, 3D lunar surface is reconstructed by SFS theory fast, and is rendered by improved Hapke illumination model. It is proved that 3D lunar surface is preferably reconstructed and simulated by this method within permitted precision.
