摘要
综合采用了邻域和平面上提取边界点的思想 ,提出了一种新的在二维平面上提取边界点的方法 ;并在曲面局部近似一个平面的前提下把它推广到三维空间 ,从而形成了一种可直接在三维空间对任意复杂形状曲面进行边界点提取的
This paper synthesized the ideas of neighborhood a nd extracting boundary points in 2-dimensional plane, and presented a new approac h for 2D boundary points′extraction. Based on the fact that local surface appro aches to a plane, the method is extended to 3D spaces, which can abstract bound ary points in 3D spaces directly and can adapt to any shape of complicated surfa ces.
