Finally, pentyl acetate and benteine could be respectively synthesized by esterification reaction in the presence of nanometer rare earth composite solid superacids (SO_4)~(2-)/ZrO_2-Gd_2O_3 and (SO_4)~(2-)/ZrO_2-Nd_2O_3. The effects of reaction time, reaction temperature, the mol ratio of acid to alcohol and the use level of catalyst on esterification yield were discussed. In the end, we obtained their optimal reaction conditions.

The synthesis scheme we developed can deal with changes in visibility, produce perspectively correct views and handle the distortion around the circumferences in the synthesized views. In our scheme, the area without corresponding points was first determined by using Fourier transformation in order to deal with distortion problem, within the mutual overlapped area the z-buffer values of matched key points were computed so that the visibility in novel views can be handle correctly, lastly the common points in new views are rendered through epipolar geometry constraint.

算法的步骤为：利用傅立叶变换方法确定相邻源图像无对应点的区域；然后，利用尺度空间和相位一致原理在共同区域提取及匹配边缘上的关键点，计算其深度值，并在新图像中由该值判别虚拟图像中的可见性；再由关键点恢复极线约束，通过极线间的位置和颜色插值生成虚拟图像中有对应区域的一般点；在确定极线位于无对应点区域段后，利用加权平均或放大插值的方法实现了源图像无对应点区域在虚拟图像中的自然过渡。
