METHOD FOR OPTICALLY MEASURING THREE-DIMENSIONAL COORDINATES AND CALIBRATION OF A THREE-DIMENSIONAL MEASURING DEVICE

摘要

A method for scanning and obtaining three-dimensional (3D)l coordinates is provided. The method includes providing a 3D measuring device having a projector, a first camera and a second camera. The method records images of a light pattern emitted by the projector onto an object. A deviation in a measured parameter from an expected parameter is determined. The calibration of the 3D measuring device may be changed when the deviation is outside of a predetermined threshold.
