UPDATING CALIBRATION OF A THREE-DIMENSIONAL MEASUREMENT SYSTEM

摘要

A method of calibrating a three-dimensional measurement system having a plurality of cameras and at least one projector is provided. The method includes performing a full calibration (100) for each camera (118, 120, 122, 124) /projector (128) pair where the full calibration generates at least two sets of correction matrices. Subsequently, an updated calibration (200) is performed for each camera(118, 120, 122, 124)/projector (128) pair. The updated calibration (200) changes less than all of the sets of correction matrices.
