ORB_SLAM2 project notes
The specific slam environment configuration can refer to this Daniel blog.
Here is mainly to record some of the lapses in the installation process.
During the installation of sudo, there may be occasions when certain packages are unable or dependent to be fetched. At this time, follow the ubantu prompt, execute update, or --fix-missing.
sudo apt_get update
Follow the steps in the blog, install it all the way, pay attention to the version problem. One of the pits I encountered here is when running to
./build.sh
When this command was executed, the computer ran to about 50% or 60% and froze. After that, it took a while to check on it and thought that some of its dependencies had not been installed, but it was actually the pot of the build.sh file. Open it and see that the compile command used in it is make -j , which causes the computer to freeze because the configuration is low (I used a 3G virtual machine, but it still stuck), just put the build.sh file make -j changed to make to respect make -j changed to make a difference, it is explained in Daniel's blog there, stop drilling here.
Another one, when running the routine downloaded online, it is the following command
./Examples/Monocular/mono_tum Vocabulary/ORBvoc.txt Examples/Monocular/TUMX.yaml PATH_TO_SEQUENCE_FOLDER
Remember to change PATH_TO_SEQUENCE_FOLDER to the path of your own data set, which is the path of the entire data set folder. Then it will run successfully ~
