Try installing ros-indigo-opencv3 (apt-get)
Despite compiling and installing opencv 3.1.0, I had the same error. But it got fixed after that.
Or else, add LD_LIBRARY PATH as usr/local/bin (if that's where your symbolic link files are stored) to your .bashrc.
In case, nothing works, you should check whether cv2.so exists in your /usr/local/lib/python2.7/site-packages & ../dist-packages directories. If not, you should consider reinstalling opencv again.
Hope this helps!
