What is Eagleye

Eagleye is an open-source software for vehicle localization utilizing GNSS and IMU[1]. Eagleye provides highly accurate and stable vehicle position and orientation by using GNSS Doppler[2][3][4][5][6]. The flowchart of the algorithm is shown in the figure below. The algorithms in this software are based on the outcome of the research undertaken by Machinery Information Systems Lab (Meguro Lab) in Meijo University.

Recommended Sensors

GNSS receiver

• Ublox ZED-F9P / C099-F9P
• Septentrio Mosaic development kit with GNSS antenna

GNSS Antenna

• Ublox ANN-MB Series
• Tallysman TW2710

IMU

• Tamagawa Seiki TAG300 Series
• ANALOG DEVICES ADIS16475

Wheel speed sensor

• Eagleye uses vehicle speed acquired from CAN bus.

How to install

RTKLIB

Clone and Build MapIV's fork of RTKLIB. You can find more details about RTKLIB here.

sudo apt-get install gfortran
cd $HOME
git clone -b rtklib_ros_bridge_b34 https://github.com/MapIV/RTKLIB.git
cd $HOME/RTKLIB/lib/iers/gcc/
make
cd $HOME/RTKLIB/app/consapp
make 

ROS Packages

Clone and build the necessary packages for Eagleye.

cd $HOME/catkin_ws/src
git clone --recursive https://github.com/MapIV/eagleye.git
git clone https://github.com/MapIV/rtklib_ros_bridge.git
git clone https://github.com/MapIV/nmea_comms.git
git clone https://github.com/MapIV/nmea_ros_bridge.git
cd ..
rosdep install --from-paths src --ignore-src -r -y
catkin_make -DCMAKE_BUILD_TYPE=Release

Configuration

GNSS

ublox f9p settings

septentrio mosaic settings

IMU

1. IMU settings.

• Output rate 50Hz

2. Check the rotation direction of z axis of IMU being used. If you look from the top of the vehicle, if the left turn is positive, set pitch to 3.14159 in eagleye/eagleye_util/tf/config/sensors_tf.yaml.

     pitch: 3.14159
   

Start each sensor driver

1. Check if wheel speed (vehicle speed) is published in /can_twist topic.

• Topic name: /can_twist
• Message type: geometry_msgs/TwistStamped twist.liner.x

2. Check if the IMU data is published in /imu/data_raw topic.

3. Start RTKLIB.

   ex. single point positioning

    cd $HOME/RTKLIB
    bash rtklib_ros_bridge_single.sh
   

   ex. Real Time Kinematic

    cd $HOME/RTKLIB
    bash rtklib_ros_bridge_meijo_rtk.sh
   

4. Check if RTKLIB is working by execute the following command in the terminal. If the RTKLIB is working correctly, positioning information is appeared continuously in the terminal.

    status 0.1  
   

5. Start rtklib_ros_bridge.

    roslaunch rtklib_bridge rtklib_bridge.launch   
   

6. Start nmea_comms in f9p or nmea_ros_bridge in mosaic.

    roslaunch nmea_comms f9p_nmea_sentence.launch
   

   or

    roslaunch nmea_ros_bridge nmea_udp.launch
