An exploratory research on the length measuring error calibration of industrial CT is carried out to move forward on the traceability of industrial CT in dimensional measurement.The length measuring error of industrial CT can be classified to two types;sphere distance error and plane distance error.For the widely accepted sphere distance error,a tiny forest-ball is developed,and calibrated by a high precision coordinated measuring machin.Then the tiny forest-ball is used to calibrate an industrial CT called...

1别言 近年来工业计算机断层扫描成像系统(Computed Tomography,CT)以其优异的三维成像和内外部结构检测能力,正在从传统的无损检测
领域,拓展到几何坐标测量领域。一套完整的工业CT系统可以实现对工业零部件内外部结构非接触、无损伤的测量。与传统的坐标测量机(Coordinate M
