Rosbag replay simulation#

Steps#

  1. Download and unpack a sample map.

    • You can also download the map manually.
    gdown -O ~/autoware_map/ 'https://docs.google.com/uc?export=download&id=1A-8BvYRX3DhSzkAnOcGWFw5T30xTlwZI'
    unzip -d ~/autoware_map/ ~/autoware_map/sample-map-rosbag.zip
    
  2. Download the sample rosbag files.

    gdown -O ~/autoware_map/ 'https://docs.google.com/uc?export=download&id=1VnwJx9tI3kI_cTLzP61ktuAJ1ChgygpG'
    unzip -d ~/autoware_map/ ~/autoware_map/sample-rosbag.zip
    
  3. Check if you have ~/autoware_data folder and files in it.

    $ cd ~/autoware_data
    $ ls -C -w 30
    image_projection_based_fusion
    lidar_apollo_instance_segmentation
    lidar_centerpoint
    tensorrt_yolo
    tensorrt_yolox
    traffic_light_classifier
    traffic_light_fine_detector
    traffic_light_ssd_fine_detector
    yabloc_pose_initializer
    

    If not, please, follow Manual downloading of artifacts.

Note#

  • Sample map and rosbag: Copyright 2020 TIER IV, Inc.
  • Due to privacy concerns, the rosbag does not contain image data, which will cause:
    • Traffic light recognition functionality cannot be tested with this sample rosbag.
    • Object detection accuracy is decreased.

How to run a rosbag replay simulation#

Using Autoware Launch GUI

If you prefer a graphical user interface (GUI) over the command line for launching and managing your simulations, refer to the Using Autoware Launch GUI section at the end of this document for a step-by-step guide.

  1. Launch Autoware.

    source ~/autoware/install/setup.bash
    ros2 launch autoware_launch logging_simulator.launch.xml map_path:=$HOME/autoware_map/sample-map-rosbag vehicle_model:=sample_vehicle sensor_model:=sample_sensor_kit
    

    Note that you cannot use ~ instead of $HOME here.

    after-autoware-launch

    ⚠️ You might encounter error and warning messages in the terminal before playing the rosbag. This is normal behavior. These should cease once the rosbag is played and proper initialization takes place

  2. Play the sample rosbag file.

    source ~/autoware/install/setup.bash
    ros2 bag play ~/autoware_map/sample-rosbag/sample.db3 -r 0.2 -s sqlite3
    

    ⚠️ Due to the discrepancy between the timestamp in the rosbag and the current system timestamp, Autoware may generate warning messages in the terminal alerting to this mismatch. This is normal behavior.

  3. To focus the view on the ego vehicle, change the Target Frame in the RViz Views panel from viewer to base_link.

    change-target-frame

  4. To switch the view to Third Person Follower etc, change the Type in the RViz Views panel.

Using Autoware Launch GUI#

This section provides a step-by-step guide for using the Autoware Launch GUI to launch and manage your rosbag replay simulation. offering an alternative to the command-line instructions provided in the previous section.

Getting Started with Autoware Launch GUI#

  1. Installation: Ensure you have installed the Autoware Launch GUI. Installation instructions.

  2. Launching the GUI: Open the Autoware Launch GUI from your applications menu. GUI_screenshot_for_launching

Launching a Logging Simulation#

  1. Set Autoware Path: In the GUI, set the path to your Autoware installation. GUI_screenshot_for_setting_Autoware_path
  2. Select Launch File: Choose logging_simulator.launch.xml for the lane driving scenario. GUI screenshot for selecting launch file
  3. Customize Parameters: Adjust parameters such as map_path, vehicle_model, and sensor_model as needed.
