teaser

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 availble as a separate header-only library.

Installation

APT installation for Ubuntu 16.04 and 18.04 (Fast)

Set up keys

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 0D97B6C9

Add the repository to the sources list. On Ubuntu 18.04 run:

sudo sh -c 'echo "deb [arch=amd64] http://packages.usenko.eu/ubuntu bionic main" > /etc/apt/sources.list.d/basalt.list'

On Ubuntu 16.04 run:

sudo sh -c 'echo "deb [arch=amd64] http://packages.usenko.eu/ubuntu xenial main" > /etc/apt/sources.list.d/basalt.list'

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.
