摘　　要：根据在不同照明情况下获得的多幅图像,提出一种三维曲面重构方法。先运用解方程组、复化积分计算表面高度值,再利用变分和有限差分思想对所得拟合表面进行进一步的迭代和修正,从而获得最佳再建表面。通过对选取曲面的算例分析,表明该算法具有一定的准确性和适用性。This paper presents a method for3D surface reconstruction based on multiple imagines with different illumination.Surface height can be obtained by solving system of equations and applying composite numerical integration,then the fitted surface can be further iterated and modified according to variational calculus and finite difference method,so the best reconstruction surface is obtained.By the analysis of the example,the algorithm is verified to be accurate and applicable.
