1. Surface triangulations based-on 3D arbitrary point-sets are widely applied in CAGD/CAD and reverse-engineering, etc. 根据三维散乱点集构造曲面剖分在CAGD/CAD、反求工程等方面有着十分广泛的应用。
2. Triangulations from 3d scattered point sets play an important role in surface modeling. The applied criterion determines the final triangulation. 由3 D散乱点集构造三角剖分在曲面造型中有着十分重要的作用,而剖分所采用的优化准则决定了最终的剖分结构。
3. To ensure the existence of boundary sides and faces, local tetrahedralization method is adopted, needing add no node into the origin surface triangulations. 采用局部剖分的方法来保证边界的完整性,不需要添加新的节点到原始表面三角形中。
4. The algorithm first describes the left image with DT mesh. As feature points, the vertexes of triangulations are matched in the right image for finding their corresponding points. 本文算法首先对立体图像对中的左图像进行DT网格剖分,把各三角形的顶点作为“特征点”在右图像中寻找它们的匹配点。
