Polygonization of implicit surfaces with constructive solid geometry 超形有兩個值得重視的特點。
Moving from single dislocations to ensemble effects , recovery and polygonization are reviewed . recrystallization is also introduced and described phenomenologically 由單一差排進而轉(zhuǎn)往整體效應(yīng),并回顧回復(fù)及多角形化。亦由現(xiàn)象面介紹及描述再結(jié)晶。
Data preprocessing refers to the process of polygonization , smoothing , decimation and registration . the flow and main steps of data preprocessing are described here . several specific cases , for example the sampling method based on chordal deviation , the feature based registration , are discussed 本文研究和討論了點云預(yù)處理的基本流程和主要步驟,研究點云光順的高斯濾波,中值濾波和平均濾波方法、點云精簡的弦高差算法和多視點云特征對齊的方法。
