Abstract

Propose a length measurement error calibration method for X-ray 3D dimension measuring machine based on forest sphere. Based on the length measurement error calibration method of the X-ray 3D dimension measuring machine based on forest balls, establish an evaluation model for measurement uncertainty and analyze the sources of various uncertainties. Based on measurement examples, this paper elaborates on the process of evaluating the measurement uncertainty of the length measurement error of the X-ray 3D dimension measuring machine based on forest balls, calculates its extended uncertainty, and provides reference for the evaluation of the measurement uncertainty of the length measurement error of the X-ray 3D dimension measuring machine.
