How to re-play rosbag dataset

• Download .bag file & copy to workspace

• Select scenario data by modifying the launch file.

  • Of course, rosbag options can be added through the "option" argument.

• View odometry visualization of sensor fusion method

roslaunch low_cost_odometry [sensor_fusion_method].launch

How to extract trajectory data

• Edit launch file

• Parameters

  • msg_type: argment name to select rosmsg type

  • extracted_topic: argment name to extract topic

  • scene_number: scenario folder name

  • tum_file_name: output tum file name

Installation EVO

pip install evo --upgrade --no-binary evo

plot output data

• Go to tum files directory
