IMU tools for ROS

Overview

IMU-related filters and visualizers. The stack contains:

  • imu_filter_madgwick: a filter which fuses angular velocities, accelerations, and (optionally) magnetic readings from a generic IMU device into an orientation. Based on the work of [1].

  • imu_complementary_filter: a filter which fuses angular velocities, accelerations, and (optionally) magnetic readings from a generic IMU device into an orientation quaternion using a novel approach based on a complementary fusion. Based on the work of [2].

  • rviz_imu_plugin a plugin for rviz which displays sensor_msgs::Imu messages

Installing

From source

Create a catkin workspace (e.g., ~/ros-hydro-ws/) and source the devel/setup.bash file.

Make sure you have git installed:

sudo apt-get install git-core

Download the stack from our repository into your catkin workspace (e.g., ros-hydro-ws/src; use the proper branch for your distro, e.g., groovy, hydro...):

git clone -b <distro> https://github.com/ccny-ros-pkg/imu_tools.git

Install any dependencies using rosdep.

rosdep install imu_tools

Compile the stack:

cd ~/ros-hydro-ws
catkin_make
