I have been trying to use image_view to to view bottom camera of ardrone simulated in Gazebo but not able to see anything. The below command I've used:

rosrun image_view image_view image:=/ardrone/bottom/image_raw

The gui of camera is just appeared for about 3 seconds before it freezes. I have just upgraded to OpenCV3 anyway. Has it something to do with OpenCV3?

Anything that could go wrong?

I found out that after reinstalling the ROS solves the issue by running the following command along with setting up the appropriate ROS environment variables:

sudo apt-get install ros-kinetic-desktop-full

Did you switch to the bottom camera? I don't know about this simulated model of the AR.Drone 2.0, but the real one only allows the use of one camera at a time so you have to make a service call to toggle cameras (his is a limitation of the drone, not any ROS package that you're using).

To switch to the bottom camera, try using

rosservice call /ardrone/togglecam

As for the OpenCV question, I'm not sure.
