CALIBRATING A VISUAL GUIDED ROBOT WITH TWO IMAGING DEVICES

摘要

Calibrating a first co-ordinate frame (1) of an indexing means (4) in a second frame (3) of reference of a rigidly attached sensing means (2a, 2b). Measuring first positions of a plurality of light sources (6) or reflecting points relative to the sensing means corresponding to a first absolute position (7) of the indexing means (4). Moving the indexing means (4) to a desired second absolute position (8) and again measuring. Eventually repeating such a movement as a known, unique transform for transformation means. Suitable in robotic drilling (end effector) with six degrees of freedom (6DOF) configuration.
