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 然后通過復(fù)化積分確定選取點(diǎn)的高度值,再利用變分和有限差分思想對所得擬合表面進(jìn)行進(jìn)一步的迭代和修正,從而減小誤差,獲得最佳再建表面。
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 根據(jù)多幅圖像上固定位置一點(diǎn)灰度值的變化列多個非線性方程,通過求解該非線性方程組,確定出各選取點(diǎn)的法向量;然后通過復(fù)化積分確定選取點(diǎn)的高度值,并利用變分和有限差分思想對所得表面進(jìn)行進(jìn)一步的迭代和修正,以減小重構(gòu)誤差。
