  5. In this paper, i will present some algorithms of polyhedral visual hull reconstruction : ( 1 ) polyhedral v isual h ull generation a igorithm b ased one dge - pool - searching, which constrains the 3 - d intersections into the 2 - d planes intersection via the epipolar theory to reduce the complexity a nd c an r educe t he t imes f or c ones t o b e p rejected o nto t he i mage p lanes, i n which we induced the index list to every points on the surface of object, and connected the related points to get sub polygons on surface and in turn get the mesh model, we replace triangulation process of disordered points cloud by edge - pool searching. ; ( 2 ) reconstruction based on degenerated - polygon - intersection, which have the following improvements on traditional bull intersection : using degenerated polygon to orga nize intersected area on cone face, which may be discontinuous ; a fast intersection algorithm of polygons on the cone face based on degenerated polygons, which is consistent between the continuous polygons and the discontinuous ones. the intersection of degenerated polygons is similar to the convergence of two ordered lists, which is comparably simple to the bull operation ; ( 3 ) reconstruction algorithm based on ray - tracing, in which all the rays that run through the vertex on silhouette of object will intersect with all the cones correspondent to other silhouette, and we have to calculate the intersection of all such line segments, the endpoints of which are considered to lie on the surface of object and we will get the point cloud on the surface of object

    同時利用共極線原理把三維計算投影到二維平以降低求交計算的復雜度,該演算法可以減少光向圖像平投影計算的次數,以邊池搜索取代散亂點集上進行的三角剖分; ( 2 )基於退化多邊形求交的多可見殼模型重構,系統引入退化多邊形的概念,把的交集中不連通的部分用一個退化多邊形來表示,並引入了新的基於退化多邊形的求交演算法,與傳統多可見殼重構相比,該演算法有以下幾點創新:在圖像平以退化多邊形組織投影和物輪廓的交集,把任意與物輪廓的交集歸一到一個退化多邊形;基於退化多邊形的二維平上多邊形快速相交演算法,該演算法在一定程度上就是兩個有序鏈表的合併,大大簡化了先前的布爾求交計算; ( 3 )基於光線跟蹤的演算法,該演算法中所有通過輪廓點的光線和對應其它圖像輪廓的光進行求交計算,最後得到每次求交計算得到線段的交集,該線段的點就認為是物點,從而得到物的點雲。
