When I do the camera calibration, we can get the intrinsic parameter and extrinsic parameter, but i realize that using opencv library, the calibrated extrinsic parameter are the extrinsic parameter of each calibration image with respect to the camera, how can i know the extrinsic parameter of the camera with respect to the world reference?

There is no world reference. What you expect is similar to asking OpenCV where on the world the camera is positioned. Your patterns are moving so that there is no sound definition of a world frame.
