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.
針對復雜曲面數據測量及曲面重構的要求,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品點數據的處理方法,以及CAD模型的重構技術,分析了反求建模中存在的問題。
