与己有的三维变换方法相比较，该方法不但成功地填补了由于投影区域扩张而产生的第一类空洞，而且成功地填补了由于空间深度非连续物体相互遮挡而产生的第二类空洞，从而方便地实现了虚拟环境中的漫游；基于物体表面深度的连续性，本文提出了一个位移预测方法? ?此方法可以从单幅参考图象获得逆映射过程中所需要的目标图象的位移信息，从而大大提高了算法的效率：与通常的正向映射算法相比，此算法克服了多幅参考图象所带来的计算量成倍增长等问题，而且误差较小。 2 ）基于极线几何的快速逆映射算法。利用参考图象的边界信息与隐含的遮挡关系，以及极线几何的性质，本文第三章提出了一个基于极线几何的快速3 ‘一中国科学院软件研究所博士学位论文基于图象的快速绘制技术的研究逆映射算法，从多幅参考图象精确合成当前视点目标图象。 - Presents a method for sfs based on model of polyhedron . we carry out the algorithm by solving a overdetermined linear equations which is constructed through the distributing of the vector field . the algorithm can reconstruct 3d surface from photometric stereo image given the direction of illumination
针对目前“从明暗恢复物体形状方法”存在的问题，提出了以多面体模型为基础的快速算法，根据向量场的分布建立关于物体表面深度信息的超定线性方程组，在最小二乘意义下求得物体表面的深度值。 - Moreover , we observed the concentration profiles of the ion - implanted samples and the diffused samples by c - v method , and discovered that the carrier concentration decreased with increasing of the diffusion depth . whereas , the peak concentration of the ion - implanted samples located at 0 . 248151 u m beneath the surface and the peak concentration of the diffused samples located at the surface . furthermore , the carrier concentration of mnas source diffused sample as high as 102 % m3can be obtained , and the surface was much smoother compared with that of the pure mn source diffused sample
发现两种掺杂方法的载流子浓度大体上都是随着扩散深度的增加而下降，不同的是离子注入样品的载流子最高浓度处于离表面深度0 . 248151 m处，而扩散样品的载流子最高浓度处于表面，并掺锰（ mn ）砷化锌（ gaas ）材料性质的研究且还发现相对于纯mn源扩散样品来说， mnas源扩散样品的表面较为光滑，且表面载流子浓度高达1020 cm ’数量级。
