Based on data cloud , which is measured from 3 - coordinate measuring machine ( cmm ) or so , an algorithm to search lopological structure from 3d unorganized points using envelopment - box technology is proposed in this thesis . based on this method , we searching neighbor points of sampling point . we also improve the max - min angle criteria to realize local triangulation , and then get the normal of sampling point from the triangulation
本文以測量得到的曲面數(shù)據(jù)點點云為基礎(chǔ)，提出了一種基于包圍盒的自動尋找三維散亂數(shù)據(jù)點之間拓?fù)浣Y(jié)構(gòu)的方法，采用該方法尋找采樣點的鄰域結(jié)點，并對三角剖分中的典型優(yōu)化準(zhǔn)則?最小內(nèi)角最大準(zhǔn)則提出了改進(jìn)，按照改進(jìn)后的優(yōu)化準(zhǔn)則實現(xiàn)了采樣點的局部三角劃分，并進(jìn)一步求解得到采樣點的法向量，依據(jù)法向量及鄰域拓?fù)潢P(guān)系在二次曲面的基礎(chǔ)上實現(xiàn)了散亂數(shù)據(jù)曲面重構(gòu)中的數(shù)據(jù)點的自動分類。
