摘要

The arrangement has two cameras (3) that are fastened to a robot (1), where the cameras are moved along with the robot. The cameras are arranged with different orientations in patterns (5, 6), so that the patterns within a working area are engaged with each camera. The patterns are used as continuous pattern by overlapping the patterns with another similar pattern to form a moire pattern. An independent claim is also included for method for improving accuracy of a robot within a working area.
