Basalt
For more information see https://vision.in.tum.de/research/vslam/basalt
This project contains tools for:
- Camera, IMU and motion capture calibration.
- Visual-inertial odometry and mapping.
- Simulated environment to test different components of the system.
Some reusable components of the system are available as a separate header-only library (Documentation).
There is also a Github mirror of this project to enable easy forking.

Update the Ubuntu package index and install Basalt:
sudo apt-get update
sudo apt-get install basalt
Source installation for Ubuntu >= 18.04 and MacOS >= 10.14 Mojave
Clone the source code for the project and build it. For MacOS you should have Homebrew installed.
git clone --recursive https://gitlab.com/VladyslavUsenko/basalt.git
cd basalt
./scripts/install_deps.sh
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo
make -j8
NOTE: It is possible to compile the code on Ubuntu 16.04, but you need to install cmake-3.10 or higher and gcc-7. See corresponding Dockerfile as an example.
