Hi,recently，i am using the bluerov2.I want to run the orbslam2 using the camera of the bluerov2. And,when i used the camera,i can not found the message for ROS topic "camera_info",so that the camera calibration work can not be done.Can you give me some advice to help me solve this problem? Thank you very much!

You will need to extract the camera info and create the topic for it, be free to send a PR.
