Can't view the pointclouds in the rviz
I use the bumblebee2 get stereo picture of the left and right image,and use the stereo_image_proc package to deal with it . i got the rect image and disparity image with no problem, and use the command of "rostopic echo /stereo_camera/pointclouds2",got the pointclouds data as followed then i want to use the rviz to see the pointclouds picture ,it failed.
I think it's not the problem of "tf data",as i use the bumbleebee on line get the pointclouds picture by rviz have the same warn of "tf data",but it's no matter to view the pointclouds in the rviz!
