简介
之前一篇博客：“ubuntu16.04运行VINS-MONO实验总结” 已经在笔记本中成功运行了VINS-MONO。然后想在TX2上运行看看。
1.ceres-solver安装
方法1：（ceres官网给的教程）
sudo apt-get install cmake
sudo apt-get install libgoogle-glog-dev
sudo apt-get install libatlas-base-dev
sudo apt-get install libeigen3-dev
sudo apt-get install libsuitesparse-dev
sudo add-apt-repository ppa:bzindovic/suitesparse-bugfix-1319687
sudo apt-get update
sudo apt-get install libsuitesparse-dev
下载ceres安装包，并安装。 github地址
tar zxf ceres-solver-1.14.0.tar.gz
mkdir ceres-bin
cd ceres-bin
cmake ../ceres-solver-1.14.0
make -j3
make test
make install
方法2:（按照视觉SLAM14讲高博给的方法）
sudo apt-get install liblapack-dev libsuitesparse-dev libcxsparse3.1.2 libgflags-dev libgoogle-glog-dev
注意ubun16.04系统需要将libcxsparse3.1.2换成libcxsparse3.1.4
tar zxf ceres-solver-1.14.0.tar.gz
mkdir build
cd build
cmake ..
make -j3
sudo make install
编译过程出现错误，eigen需要大于3.3.4版本，之前笔记本安装的eigen版本是3.2.10也能够通过编译，于是在网上下载eigen安装包，我选择的版本是eigen 3.3.7，重新安装。
tar zxf eigen-3.3.7.tar.gz
mkdir build
cd build
cmake ..
sudo make install
Ceres库的头文件安装在"/usr/local/include/ceres/“目录下，库文件安装在”/usr/local/lib/“目录；eigen库的头文件安装在”/usr/local/include/eigen3/"目录下。
如下图所示，ceres似乎已经安装成功！！
2. 运行小觅摄像头
1）运行 mynteye 节点
cd [path of mynteye-s-sdk]
make ros
source ./wrappers/ros/devel/setup.bash
roslaunch mynt_eye_ros_wrapper mynteye.launch
2）打开另一个命令行运行 VINS-MONO
cd ~/vins_mono_ws
source devel/setup.bash
roslaunch vins_estimator mynteye.launch
如下图所示，报错了！！！应该是调用ceres求解器不成功，系统初始化成功之后，轨迹一下子飘了。
问题解决思路：
1)卸载之前安装的ceres
sudo rm -rf /usr/local/include/ceres
sudo rm -rf /usr/local/lib/cmake/Ceres/
sudo rm -rf /usr/local/lib/libceres.a
2)卸御之后重新安装eigen（过程参考这篇文章“Ubuntu 16.04, 卸载&安装 Eigen”）
重新编译之后发现还是出现问题，如下图所示：
这是什么问题？？？用了catkin_make_isolated,编译能通过，不过在运行vins-mono的过程中还是和之前的问题一样，似乎无法调用ceres优化库。
