摘要: An object (10) is positioned in fixed relation to a measuring axis (36) without regard centering the on and at least one series of data samples (101-109) correlated distance between points angularly spaced intervals surface feature (14, 17) are used. To determine center (165) first (14) analyzed identify (102, 106, 108) corresponding lying maximum inscribed circle (169) whose corresponds (14). measure second (17) determined define vector indicating positional offset center. A signal (74) adjusted with that provide coordinate-corrected be used as basis for centered measurement.
