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 available as a separate header-only library (Documentation).

There is also a Github mirror of this project to enable easy forking.

Visual-Inertial Odometry and Mapping:

Calibration (explains implemented camera models):

Calibration (demonstrates how these tools can be used for dataset calibration):

  • The TUM VI Benchmark for Evaluating Visual-Inertial Odometry, D. Schubert, T. Goll, N. Demmel, V. Usenko, J. Stückler, D. Cremers, In 2018 International Conference on Intelligent Robots and Systems (IROS), [DOI:10.1109/IROS.2018.8593419], [arXiv:1804.06120].

Calibration (describes B-spline trajectory representation used in camera-IMU calibration):

Optimization (describes square-root optimization and marginalization used in VIO/VO):

  • Square Root Marginalization for Sliding-Window Bundle Adjustment, N. Demmel, D. Schubert, C. Sommer, D. Cremers, V. Usenko, In 2021 International Conference on Computer Vision (ICCV), [arXiv:2109.02182]

Installation

APT installation for Ubuntu 20.04 and 18.04 (Fast)

Set up keys, add the repository to the sources list, update the Ubuntu package index and install Basalt:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0AD9A3000D97B6C9
sudo sh -c 'echo "deb [arch=amd64] http://packages.usenko.eu/ubuntu $(lsb_release -sc) $(lsb_release -sc)/main" > /etc/apt/sources.list.d/basalt.list'
sudo apt-get update
sudo apt-get dist-upgrade
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.
