先修课程：负责教授同意。变分微积分与最佳化之关系及其在工程最佳化上之应用、端点条件、不连续最佳化程序、无限制及有限制条件最佳化问题、直接法及实际最佳化设计应用等。 - Thirdly , the surface height at the point can be gotten by applying composite numerical integration . according to variational calculus and finite difference method , the fitted surface is further iterated and modified , so the best reconstruction surface can be finally obtained
然后通过复化积分确定选取点的高度值，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，从而减小误差，获得最佳再建表面。 - A new system of nonlinear equations can be formed from the variation gray of same point in multiple images and the optimum solution of the system can be obtained , so that the normal vector at that point of the surface can be defined . then we can get the surface height at the point by applying composite numerical integration . according to variational calculus and finite difference method , the fitted surface is further iterated and modified , so the reconstruction error can be reduced
根据多幅图像上固定位置一点灰度值的变化列多个非线性方程，通过求解该非线性方程组，确定出各选取点的法向量；然后通过复化积分确定选取点的高度值，并利用变分和有限差分思想对所得表面进行进一步的迭代和修正，以减小重构误差。
