kandi X-RAY | g2o Summary

g2o is a C++ library typically used in Automation, Robotics applications. g2o has no bugs, it has no vulnerabilities and it has medium support. You can download it from GitHub.

g2o is an open-source C++ framework for optimizing graph-based nonlinear error functions. g2o has been designed to be easily extensible to a wide range of problems and a new problem typically can be specified in a few lines of code. The current implementation provides solutions to several variants of SLAM and BA. A wide range of problems in robotics as well as in computer-vision involve the minimization of a non-linear error function that can be represented as a graph. Typical instances are simultaneous localization and mapping (SLAM) or bundle adjustment (BA). The overall goal in these problems is to find the configuration of parameters or state variables that maximally explain a set of measurements affected by Gaussian noise. g2o is an open-source C++ framework for such nonlinear least squares problems. g2o has been designed to be easily extensible to a wide range of problems and a new problem typically can be specified in a few lines of code. The current implementation provides solutions to several variants of SLAM and BA. g2o offers a performance comparable to implementations of state-of-the-art approaches for the specific problems (02/2011).

            Operation not permitted on gitlab-runner
            Asked 2022-Jan-04 at 17:45

            I'm trying to run a gitlab ci on my own server. I registered gitlab-runner in a separated machine using privileges



            Answered 2022-Jan-04 at 17:44

            I entered the container from the runner machine while the ci was running and I noticed that the repository was cloned as root but the build directories were created under a user. The cofigure_file command is trying to modify a file from the repository, so it's like user is trying to modify a file created as root (when cloned). I didn't manage to make the gitlab-runner software clone the repository as user. Instead, my workaround was to change the permissions of the folder before building. My .gitlab-ci.yml looks like this now

            CMake does not set variables for g2o
            Asked 2021-Aug-02 at 12:31

            On macOS 11.0, I downloaded and built g2o (https://github.com/RainerKuemmerle/g2o) and installed it using cmake --install . I then tried to include it in my own project via CMake like this (CMakeLists.txt):



            Answered 2021-Aug-02 at 12:31

            why CMake did find g2o but not set the variables accordingly.

            FindG2O.cmake does not set these variables, so they are not set. The variables checked for G2O_FOUND to be set are G2O_STUFF_LIBRARY AND G2O_CORE_LIBRARY AND G2O_INCLUDE_DIR AND G2O_SOLVERS_FOUND.

            There is no rule that find_package has to set _LIBRARIES or _INCLUDE_DIRS variables - every package is a little different, consult that particular package. If writing FindXXX file, use interface or imported libraries instead of variables.

            Undefined Reference While Compiling ROS ORB_SLAM2
            Asked 2021-Apr-22 at 14:53

            I am trying to compile this version of ORB SLAM2 and after fixing some library import errors, I got this:



            Answered 2021-Apr-22 at 14:53

            This is an annoying compatibility error. The ORB SLAM you are trying to use only works with Ubuntu 18.04. But, on the ROS ORB SLAM page, they have a new one called orb_slam_ros (click here) that does the same thing.

            NOTE: The new one doesn't say that it outputs ROS maps but using Octomap, you can convert a PointCloud to a Map. NOTE: This is tested in Ubuntu 20.04 ROS Noetic. As of now, 20.10 doesn't work.

            Could not load the Qt platform plugin "xcb" in "" even though it was found
            Asked 2020-Feb-07 at 19:14

            This question is asked several times in Stack Overflow. I tried methods in several discussions but it didn't work. So my OpenCV library which was built with custom Qt doesn't work properly:



            Answered 2020-Feb-07 at 19:14

            The error seems to be the Qt library conflict. The linker couldn't find the correct Qt library (installed in /opt folder) which is required by my custom built OpenCV in the conda virtual environment. This is because there is another Qt library installed in the virtual environment. And this can be found by using ldd. (Sorry, it was some time ago so I don't have the output.)

            As expected, by removing all the Qt-related libraries in the virtual conda environment, the OpenCV library which was built with Qt (installed in /opt folder) works properly as usual.
