ros kinetic comes with gazebo 7. When I start this gazebo, there is a default world including a turtlebot. This Turtlebot is equiped with an RGB-D camera. How to get the intrinsics parameters of that camera? My goal is to convert from pixel coordinate to camera coordinate and later to world coordinate.

Not sure if this would work in Gazebo sim, but do a ros topic list and poke around until you find a CameraInfo message type. It should have what you need. I am not sure how realistic the camera model is within Gazebo but I would love to find out.
