Function of "gazebo_ros_camera"?
Related to the answer to this question: http://answers.ros.org/question/19205... . I'm trying to write a C++ program that will allow me to capture a single frame from a camera in Gazebo and will be basing it on gazebo_ros_camera based on advice from that answer. Can someone explain to me what exactly is gazebo_ros_camera supposed to do? The source code documentation didn't really explain it, and the ROS wiki page only mentions it in passing in various places.
