散亂掃描 的英文怎麼說
中文拼音 [sǎnluànsǎomiáo]
散亂掃描
英文
random scanning-
After the orderly reduction methods of massive scattered data being studied, this paper proposes a partial tangent plane slicing method and a virtual second - scan line method after giving a new k - nearest algorithm to re - organize the massive data. the new proposed methods of data reduction and grey theory based unusual noisy data process can be used to generate the scan line type data and it can be directly used to reconstruct curves and surfaces. the research lays a good foundation for reconstructing the cad model in a point - line - surface manner
4 .深入研究了海量散亂數據的有序簡化技術，在提出建立海量數據點鄰接關系k -鄰近新的演算法基礎上，提出了局部切平面切片法和虛擬二次掃描線法，實現了海量數據的有序重組，通過基於灰理論的數據簡化和異常點處理新方法，生成可用於直接重構曲線曲面的掃描線類型數據，為以點?線?面方式重構cad模型打下了良好的基礎。The parts reverseeng ineering deals with mostly have freeform surfaces. the regeneration of the free form surfaces is the main task of reverse engineering. in this paper some key techniques for nurbs surface reconstruction in reverse engineering such as b - spline curve fitting, b - spline surface fitting to scattered data, b - spline surfa ce fitting to contour data and b - spline curve fairing are studied
本文研究了逆向工程中b樣條曲面重構的關鍵技術，包括b樣條曲線的擬合、散亂數據的b樣條曲面擬合、逐層掃描數據的b樣條曲面擬合以及b樣條曲線的光順。
