一.
安装BagFromImages，之前在安装的时候在cmake .. 步骤出错，现在解决，估计是 工作空间 和 环境变量 的的问题，可能是开启终端时没有配置，在运行git clone https://github.com/raulmur/BagFromImages.git BagFromImages步骤前，
1.首先执行cd ~/catkin_ws 进入catkin_ws目录;
注：前提是已经创建了catkin 工作空间，如果没有，可以参考：http://wiki.ros.org/cn/ROS/Tutorials/InstallingandConfiguringROSEnvironment
2.source devel/setup.bash sourcez这个文件可以将当前工作空间设置在ROS工作环境的最顶层；
注：然后可以通过echo $ROS_PACKAGE_PATH查看确认当前工作空间，结果应该为/home/zhangxiwu/catkin_ws/src:/opt/ros/hydro/share:/opt/ros/hydro/stacks
3.执行cd src 进入ros工作空间，即/home/zhangxiwu/catkin_ws/src
4.执行git clone...
......
执行cmake ..
执行make
没有报错。
以下是运行的记录：

bash: devel/setup.bash: 没有那个文件或目录

二. 此时BagFromImages工具应该在ROS的工作空间下面了？

一. BagFromImages终于可以正确运行了
步骤：
开启终端执行：
1. roscore 启动roscore服务；
在新的终端执行：
1. export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/home/zhangxiwu/BagFromImages 添加环境变量；
2. cd BagFromImages 进入BagFromImages文件夹；
3. rosrun BagFromImages BagFromImages test .jpg 30 test1 注意最后的一个文件名不要和之前的文件夹名重复，要不然还是会出现（核心已转储）的错误；
总结： 待生成的图像的存放在BagFromImages文件夹内；
之前出错应该是文件夹设置的太复杂了，导致出现（核心已转储）的错误，
还有，用的就是在主文件夹下面BagFromImages，
以后安装文件工具应该也安装在主文件夹下面；
