Method for calibration of a 3D measuring device

摘要

A method is used to calibrate a 3D measuring device ( 1 ). In order to calibrate any 3D measuring device ( 1 ) without specific manufacturer's know-how, one or more characterizing objects ( 15, 16, 17 ) of a reference object ( 14 ) are measured at one or more positions in measurement volume ( 12 ) of 3D measuring device ( 1 ) to be calibrated. A gauge of the measurement error is calculated from the measured values as a function of the position in measurement volume ( 12 ). From that, an error correction function is calculated (FIG. 3 ).
