Fail in building with ROS

[Kanelankai]

Hello, everyone! I have succeeded in building and testing it with monocular examples. Now I want to run it with ROS examples. However, when I built the nodes for mono, errors occurred after executing build_ros.sh. The error information is as follows: ///////////////////////////////////////////////////////////////////////////////////////////// Scanning dependencies of target Mono [ 20%] Building CXX object CMakeFiles/Mono.dir/src/ros_mono.cc.o In file included from /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../Thirdparty/g2o/g2o/types/../core/optimizable_graph.h:41:0, from /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../Thirdparty/g2o/g2o/types/../core/base_vertex.h:30, from /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../Thirdparty/g2o/g2o/types/types_seven_dof_expmap.h:34, from /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../include/LoopClosing.h:34, from /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../include/LocalMapping.h:26, from /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../include/Tracking.h:31, from /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../include/System.h:29, from /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/src/ros_mono.cc:32: /home/dars/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../Thirdparty/g2o/g2o/types/../core/jacobian_workspace.h:30:22: fatal error: Eigen/Core: No such file or directory

why i can't find build_ros.sh? Did I lose something?

[Kanelankai]

The build_ros.sh is in the ORB_SLAM2 file. It has the same path with build.sh.

I can't confirm if your problem is the same with me. In my case, "fatal error: Eigen/core :no such file or directory" is why this problem happens. Some blogs say that since orbslam2 uses Eigen 3, you can add a link to the path of Eigen 3/Eigen/core to solve this problem. I can't remember the command of adding the link. If you google "fatal error: Eigen/core :no such file or directory", I think you can find the same blog. Good luck!

[pisuto]

I find one.But I dont't know where I should change the code. fatal error: Eigen/Core: No such file or directory - ROS Answers: Open Source Q&A Forum http://answers.ros.org/question/44140/fatal-error-eigencore-no-such-file-or-directory/ Do you understand the method of the first answer?

[Kanelankai]

I solved it by executing the following: sudo ln -s /usr/include/eigen3/Eigen /usr/local/include/Eigen You can see the details from the following URL: http://askubuntu.com/questions/491067/eigen-installation-seemed-to-work-but-i-still-cant-make-eigen-work @pisuto

[pisuto]

Thank you! I solved my problem by executing the code you provide!

[pisuto]

Sorry,I met another problem.Can you help me? When I executed the code:rosrun ORB_SLAM2 MonoAR PATH_TO_VOCABULARY PATH_TO_SETTINGS_FILE I met: [ERROR] [1486956228.917143261]: [registerPublisher] Failed to contact master at [localhost:11311]. Retrying...

[Kanelankai]

Maybe you didn't launch your monocular camera or didn't run a roscore. I'm sorry but I'm not very familiar with this kind of problems.....

Sorry,I think I may bother you. Now I can execute the example,but when executing Mono,I see a black window lining WAITING FOR IMAGES. I want to know how to see the images.I try to use usb_cam,but I can't find a correct method. Can you give me some suggestions or tutorials?

[Kanelankai]

That's OK. Please don't mind.

Can you acquire the rgb image through your usb camera without using ORB-SLAM2?

If you cannot, I think you'd better check whether the driver of your camera has been installed or not.

Otherwise, I found that you can only use a Kinect or Xtion in RGBD mode, or an ordinary usb camera in mono mode due to the default settings. Since I haven't seen the contents of the code I have no idea about the details of these settings.

I succeeded in SLAM with ROS in RGBD mode with Xtion camera, When I executed it in Mono mode with an ordinary usb camera, I could only obtain images from the camera but failed to initialize. I haven't fixed this problem.

I execute:rosrun usb_cam usb_cam_node I can success the camera without ORB_SLAM2. But when using ORB_SLAM2,it shows WAITING FOR IMAGES. I don't know "a monocular input from topic /camera/image_raw run node ORB_SLAM2/Mono"means. I think my problem occur because of this. Can you help me?

[Kanelankai]

When you run the monocular examples, did you replace "PATH_TO_VOCABULARY" and "PATH_TO SETTINGS_FILE" with your own information? If you had already done it when running the codes, I'm sorry but I have no idea as well.

[pisuto]

Yes,I have already replaced these.I may try other method. I am not familiar with ROS. So I think I should learn its tutorials first. Thank you again.

[pisuto]

I solved my problem.The original location which images are got from:/camera/image_raw doesn't match with the location where images are saved by usb camera. I made them same.Then done.

Hi!

Sorry for hijacking but I have a similar problem. First it would not find the eigen sources, but doing the symlink trick mentioned earlier in the thread worked for that.

Now I have problem number 2, which is that the linker will not find the opencv libraries for some unknown reason. I'm running Ubuntu 16.10 with ROS kinetic. I could compile everything fine before I installed ROS, but after I installed ROS I get this (only showing first error message, if you want full log I can pastebin it):

[ 81%] Linking CXX executable ../Examples/Stereo/stereo_kitti CMakeFiles/mono_tum.dir/Examples/Monocular/mono_tum.cc.o: In function main': mono_tum.cc:(.text.startup+0x504): undefined reference tocv::imread(std::__cxx11::basic_string<char, std::char_traits, std::allocator > const&, int)'

Probably a very simple fix as well, but I do not know which line to alter.

Edit:

Further research shows that it has include dirs mixed up, so symlinking and installing the proper package fixed it. That is, to solve two problems, I did:

sudo apt-get install ros-kinetic-opencv3 sudo ln -s /usr/include/eigen3/Eigen /usr/local/include/Eigen sudo ln -s /opt/ros/kinetic/include/opencv-3.1.0-dev /usr/include/opencv-3.1.0-dev

I still have the above problem though. :(
