Abstract
As the rapid progress in the development of optoelectronic components and computational power, 3D optical metrology becomes more and more popular in manufacturing and quality control due to its flexibility and high speed. However, most of the optical metrology methods are limited to external surfaces. This paper proposed a new approach to measure tiny internal 3D surfaces with a scanning fiber endoscope and axial-stereo vision algorithm. A dense, accurate point cloud of internally machined threads was generated to compare with its corresponding X-ray 3D data as ground truth, and the quantification was analyzed by Iterative Closest Points algorithm.
随着光电元件和计算能力的飞速发展，三维光学计量因其灵活性和高速性在制造和质量控制领域越来越受欢迎。然而，大多数光学计量方法仅限于外部表面。本文提出了一种利用扫描光纤内窥镜和轴向立体视觉算法测量微小内部三维表面的新方法。本文生成了内部加工螺纹的高密度精确点云，并将其与相应的 X 射线三维数据作为地面实况进行比较，同时采用迭代最邻近点算法对量化结果进行了分析。
