| 摘 要： | 矿床三维可视化建模往往需要将相邻断面矿体线相连,形成三维棱柱体,来表现矿体形态.研究了相邻断面矿体线连接匹配的算法,首先,进行断面多边形的匹配对应,解决谁与谁相连的问题;其次,进行多边形的特征顶点粗匹配;最后,用这些特征点将原始多边形截成多段,找到上下各段的匹配关系,通过三角化形成矿体表面模型.通过实际矿山的验证,本算...

| Abstract: | A three-dimensional prismoid was formed by connecting adjacent sections of ore body into a three-dimensional visualization model of deposits to show the ore body shape.An algorithm for matching adjacent sections of an ore body was studied.Polygonal sections were first matched to address the question of which piece to fit where.Secondly,the characteristic vertices of the polygons were given an approximate match up.Finally,the original polygons were cut into several parts by these characteristic vertices.A ma... |
