• March 2018: Check out our release candidate with improved localization and lots of new features! PR

This repository contains maplab, an open, research-oriented visual-inertial mapping framework, written in C++, for creating, processing and manipulating multi-session maps. On the one hand, maplab can be considered as a ready-to-use visual-inertial mapping and localization system. On the other hand, maplab provides the research community with a collection of multi-session mapping tools that include map merging, visual-inertial batch optimization, and loop closure.

Furthermore, it includes an online frontend, ROVIOLI, that can create visual-inertial maps and also track a global drift-free pose within a localization map.

For documentation, tutorials and datasets, please visit the wiki.

The following articles help you with getting started with maplab and ROVIOLI:

• Installation on Ubuntu 14.04 or 16.04
• Introduction to the maplab framework
• Structure of the framework
• Running ROVIOLI in VIO mode
• Basic console usage
• Console map management

More detailed information can be found in the wiki pages.

The maplab framework has been used as an experimental platform for numerous scientific publications. For a complete list of publications please refer to Research based on maplab.

Please cite the following paper when using maplab or ROVIOLI for your research:
