I'd first check that the camera_info topic contains the data from your calibration config file. Use rostopic echo /camera_info and compare.

The next thing is always checking the ROS message graph for errors. Run rqt_graph and confirm that there are connections for camera_info and image_raw from camera driver to image_proc, and one image_rect connection from image_proc to ar_pose.
