We will present a new optical bore gage design based on, forming a ring of light on the inner surface of a bored hole and then superimposing arc sections of that ring onto one magnified video camera image which is fed to a computer for analysis. This unique 3D machine vision system provides a high-precision measurement of diameter and other geometric properties of the bore. THe presentation will outline the optics, describe the processing, and review calibration issues.
