摘要

逆向工程,或从物理对象中创建模型,越来越多地应用于许多行业,包括制造业、汽车设计和计算机动画。本文主要研究逆向工程的数据准备问题。本文的目的是在西波西米亚大学区域技术学院的计量实验室中,将蔡司LineScan光学传感器应用于三维坐标测量机上的问题进行映射。这项工作的目的是绘制传感器制造商提供的软件设置选项。传感器可以获得三种类型点的云:RSL(原始扫描线-由扫描仪直接记录的测量点,无需进一步调整),GSL(网格扫描线-减少并分组到给定步骤的网格中的点)和QSP(合格表面点-压缩并分组到给定网格中的点)。实验的评价揭示了在规定的测量条件下的理想设置。参考对象标称长度分别为100mm和500mm。评估每个传感器设置所需的数据是通过对这些物体的一系列测量获得的。实验的输出是建立扫描方法的每个选项的比较。评价步距设置为0.1 mm的GSL点为测量形状相似物体的最合适设置。对于所有测量变化,它们在±0.03 mm的选定公差范围内显示稳定的偏差。另一方面,RSL和QSP点在测量中的偏差稳定性较差。

Data Preparing for Reverse Engineering
Reverse engineering, or the creation of models from physical objects, is increasingly being used in many industries including manufacturing, automotive design, and computer animation. The presented work focuses on the issue of data preparation for reverse engineering. The aim of the thesis is to map the issues of working with the Zeiss LineScan optical sensor on a 3D coordinate measuring machine in the metrology laboratory of the Regional Institute of Technology at the University of West Bohemia. The aim of the work was to map the software setting options supplied by the sensor manufacturer. The sensor can obtain clouds of three types of points: RSL (Raw Scan Lines - measured points, directly recorded by the scanner, without further adjustments), GSL (Gridded Scan Lines - points reduced and grouped into a grid of a given step), and QSP (Qualified Surface points - compressed and grouped points into a given grid). The evaluation of the experiment revealed the ideal setting for the specified measurement conditions. Reference objects with nominal lengths of 100 mm and 500 mm were chosen. The data required for evaluating each sensor setting were obtained through a series of measurements of these objects. The output of the experiment is a comparison of each option for setting up the scanning method. GSL points with a step setting of 0.1 mm were evaluated as the most suitable setting for measuring objects with similar shapes. They showed stable deviations within the selected tolerance of ± 0.03 mm for all measurement variations. RSL and QSP points, on the other hand, showed less stability of deviations across the measurements.
