toy of dog head

The processing methed of data tested by laser scanner and reconstruction technology of CAD model in the reverse process of free-form surface were persented with toy of dog head as example. The problems appearing in reverse modeling were analyzed.
針對復(fù)雜曲面數(shù)據(jù)測量及曲面重構(gòu)的要求,以玩具狗頭為例,介紹使用三維激光掃描儀的自由曲面反求過程中產(chǎn)品點數(shù)據(jù)的處理方法,以及CAD模型的重構(gòu)技術(shù),分析了反求建模中存在的問題。
