在编译VINS-MONO时发现问题如图
差不多长这样

: error: (-5) Invalid pointer to file storage in function cvGetFileNodeByName查阅资料发现是OpenCV3与ROS兼容问题，因为indigo里面自带的是opencv2.4.8，而我要用的程序是基于opencv3的。
要解决这个问题，方法就是把cv_bridge和image_pipeline下载到本地的工作空间，并重新编译，他们基于OpenCV2可以直接编译成功。
image_pipeline:
https://github.com/ros-perception/image_pipeline
必须要先把旧版本的cv_bridge卸载掉：
sudo apt-get remove ros-indigo-cv-bridge
然后下载新版本的cv_bridge：
https://github.com/ros-perception/vision_opencv.git
然后编译成功，成功运行
