- A new concept of " connected surface projection region " is introduced . using distance function , only the points whose projections are inside this region are calculated to generate transition volume and reconstructed surface . much time of computation is saved
提出了“连接表面投影区域”概念，只对投影区域内的点进行体数据的生成和表面重建的计算，节约了表面重建的时间。 - Secondly , in this dissertation also introduces a new concept of " connected surface projection region " , and proposes a new algorithm for surface reconstruction based on projection . the zero isosurface is extracted using mt ( marching tetrahedras ) algorithm . in accordance with the intersection feature between isosurface and voxel , this dissertation made improvement in mt algorithm
然后在分析轮廓投影关系特性的基础上，给出“连接表面投影区域”的概念以及一种基于投影的体数据转化表面重建方法，选择marchingtetrahedras ( mt )算法进行基于体素的等值面重建，并根据重建的要求对mt算法进行改进。 - By taking advantages of epipolar line features and depth discontinuities in reference 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 images ， an efficient inverse wmping algorithm is pfoposed in chapter 3 for gcnerating nagcs of novel views by combining multiple eference images 帆 enhm different vie 呷 oints because continuous segnents determi 。 d by pairs ofedge pixels at co 。 spending epipolar lines are order kept ， only pairs of edge pixels in the reference 渝 明 e e necess 叨 口 cowute to obtain generalized disparity of all points in the desired image as a result ， sighficant acceleraion could be made in the endering pfo 比 鸵 two accelerating techiq 此 s e presented in this algori 山 mb accelerate the hole illing process his algorithm extends the reference images rom projection of single col ： ii ’ ected surface in previously developed nvnverse w 出 下 er to ima 驴 s captured rom complex scene in chapter 4 ， an 《 dent ibr method is prese 庇 仙 y takn ull 讪 antage of 呷 bies c 咖 the method can simulate the 3d details on sllri ： ace of object successfully he 。 叩 proach ， called rered ature mopmp consists of two pans at fst ， an origi 。 ltexture with orthogonal displacements per pixel is deco 啊 osed into a series of new t6 刀 mfcs with each 他 lug a given displacement per pixel ， called ae ， ea atures ， or lt hen hese lt e used to render the novel view by conventional texture mapping d avoid gaps n the endered hlla 驴 ， some phels are to be interpolated nd extended in the 厂 kaccoding to the depth differe eee between two neighbor pixels in the original texture as these ltlt fc … e much storage nd therefore much time is equired to install ltlt into the text ’ ufc buffec an 旧 thod is pfoposed to co 呷 fcss the ltlt ， nd the cottcspondingfclldering method is given experimental esults show that the new method is efficient ， especially n rendering those objects with a smaller depth rnge compared withtheir size ， such as relief surfaces of building
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。
