  • Method for calibration of a 3D measuring device
    Publication number: 20050154548
    Abstract: 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).
