Dataset for: A Quick Deviation Zone Fitting in Coordinate Metrology of NURBS Surfaces Using Principle Component Analysis

Attached files present a group of case studies to demonstrate applications of the developed metodology, DPCA, in coordinate metrology of various geometries. The examined cases include sculptured and free-form surfaces, as well as primitive geometric elements. Data and results are presented in Excel format. Three files are presented for each inspected geometry. The three files include: 1- Control Points of the desired CAD model 2- Point cloud captured from the fabricated product 3- The best transformation matrix obtained by DPCA registration of measured points.附件文件包含一组案例研究，用以展示所开发的方法DPCA在多种几何形状坐标计量中的应用。本次考察的案例涵盖曲面与自由曲面，以及基础几何要素。相关数据与结果均以Excel格式呈现。针对每一个被测几何对象，均提供三个配套文件，具体包括：1. 目标CAD模型的控制点；2. 从加工成品采集的点云数据；3. 通过DPCA对被测点进行配准后得到的最优变换矩阵。
