The 2D-VISION module includes a hand/eye calibration for 2D cameras and enables image processing in OpenCV. In the first step, the intrinsic camera calibration, the lens distortions of the camera are compensated. Then, in the extrinsic calibration, the connection between the pixel coordinates in the camera image and the real position (in world coordinates) of objects or the robot is established. Both calibration methods can be used directly from drag&bot with a standard calibration pattern. In drag&bot different image processing logics can be developed with OpenCV and Python. For frequent applications, such as workpiece localization on one level, there are already program templates, which only need to be adapted.
