Please specify your OS and ROS version. Also, which driver do you use? What steps have you executed?

OS : linux mint 17.1, ROS : Indigo , driver : nvidia , for the steps I followed those one : https://github.com/raulmur/ORB_SLAM

I guess now you can see the image by using usb_cam. You can try moving your camera around (translational motion is better), and the map will be shown in Rviz.

Actually it should be quick. For my case, I only move the cam for about 30 cm to make the map appear. Are there any error message in the terminal which you executed roslaunch ORB_SLAM ExampleGroovyHydro.launch

I have this warning (just when I add a camera): [ WARN] [1436447411.658984009]: MessageFilter [target=map ]: Discarding message from [unknown_publisher] due to empty frame_id. This message will only print once.

and I noticed that when I add a camera in Rviz , I have Image : No Image received , witch is abnormal because I can visualize the image by using usb_cam.!!

I'm looking to collaborate with someone who has been running ORB_SLAM. I can successfully execute the ORB_SLAM2 ROS Package using this command: roslaunch ORB_SLAM ExampleGroovyOrNewer.launch. RVIZ displays correctly as well but I've got some other questions. Can you help?
