| 摘 要： | 以单幅二维图像为研究对象，应用SFS的基本理论，首先对二维图像进行了光照的倾角和偏角的估计，在光源坐标系下计算出物体每一点的表面梯度；之后，旋转坐标系，在观察坐标系下得到物体的表面梯度；最后采用三点辛普森公式求出物体表面的高度。整个算法流程简单，求解层次分明，重构满意度较高。

| Abstract: | The single 2D image is taken as the research object and this paper applied the basic theory of SFS, firstly estimated the tilt and the slant of illumination, calculated every point of the surface gradient of the object in illumination coordinate,secondly rotated the coordinate system, getting the every point of the surface gradient of the object in observing coordinate, finally used three point Simpson formula, getting the height of the object. The entire process is simple and clear and the results of simulation showed the efficiency of the new approach. |
