i have make a static transformer for kinect camera_link frame with parent frame is base_link. I got the point cloud in the right perspective. However, the point cloud frame id shows it is still still in camera_optical_depth_frame. But i want the cloud to be in base_link frame. How can i do that ?

then i tried to follow this tutorial http://wiki.ros.org/navigation/Tutori... . This is the error it gave me

"[ERROR] [1430025149.086651320]: Received an exception trying to transform a point from "base_" to "base_link": Could not find a connection between 'base_link' and 'camera_depth_optical_frame' because they are not part of the same tree.Tf has two or more unconnected trees. "

even though i make camera link to be child frame of base link

Can you post your code for where you define the connection between base_link and camera_depth_optical_frame
