MapLab with mynteye camera

If you want run Maplab with mynteye camera, please follow the steps:

  • Download MYNT-EYE-S-SDK and follow steps to install.
  • Calibrate cameras with kalibr.
  • Record bag with mynt_eye_ros_wrapper in order to run ROVIOLI.

Record bag

cd MYNT-EYE-S-SDK
make ros
source wrappers/ros/devel/setup.bash
roslaunch mynt_eye_ros_wrapper display.launch
rosbag record -O mynt_maplab /mynteye/left/image_raw /mynteye/right/image_raw /mynteye/imu/data_raw

Run ROVIOLI

Two modes exists for running ROVIOLI in VIO mode:

  • Building from a rosbag
  • Building from a rostopic

Requirements

Building a map from a rosbag

For this tutorial, we build a map from one of the mynt datasets. Go to downlaod maplab_ex.bag, password: 9pkp

source ~/maplab_ws/devel/setup.bash
roscore&
rosrun rovioli tutorial_mynt_stereo_pinhole_equ mynt_stereo maplab_ex.bag

Then, use rviz to display.

cd ~/maplab_ws/src/maplab/applications/rovioli/mynteye
rosrun rviz rviz -d rviz-rovioli.rviz

Building a map from a rostopic

source ~/maplab_ws/devel/setup.bash
roscore&
rosrun rovioli tutorial_mynt_live_stereo_pinhole_equ mynt_stereo_live

Then, in a separate terminal, start your data source:

rosbag play maplab_ex.bag  # or start your sensor node
cd ~/maplab_ws/src/maplab/applications/rovioli/mynteye
rosrun rviz rviz -d rviz-rovioli.rviz

News

  • May 2018: maplab was presented at ICRA in Brisbane.
  • March 2018: Check out our release candidate with improved localization and lots of new features! PR

Description

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.
