ros2bagsend

A tool that uses simple logic to send topics recorded in ros2 bag one cycle at a time (not a strict cycle). https://github.com/PINTO0309/simple-ros2-processing-tools

1. Install ROS2

DISTRO=humble

sudo apt update && sudo apt install -y locales
sudo locale-gen en_US en_US.UTF-8
sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
export LANG=en_US.UTF-8

sudo apt install software-properties-common
sudo add-apt-repository universe

sudo apt update && sudo apt install curl -y
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key \
  -o /usr/share/keyrings/ros-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(. /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null
sudo apt update
sudo apt install -y \
ros-${DISTRO}-rosbag2 \
ros-${DISTRO}-vision-opencv \
ros-${DISTRO}-vision-msgs \
ros-${DISTRO}-image-pipeline

2. Install ros2bagsend

pip install ros2bagsend

3. Usage

• Send topics in units of pseudo-frames

  ros2bagsend --ros-args \
  -p bag_file_path:='test.db3'

• Specifies frames to start or end transmission frames refers to the number of times a topic is sent, not the number of topics. In the example below, topics are sent in the range from frame 5 to frame 100, skipping up to frame 4. It is advisable to check in advance which frame range should be sent using rqt or similar.

  ros2bagsend --ros-args \
  -p bag_file_path:='test.db3' \
  -p start_frame_no:=5 \
  -p end_frame_no:=100

• Only analysis of statistical information is performed Analyze the list of topic names in the bag file and the number of assumed frames. It is also possible to specify start_frame_no and end_frame_no. If statistical_analysis_only is specified, no topics are sent.

  ros2bagsend --ros-args \
  -p bag_file_path:='test.db3' \
  -p statistical_analysis_only:=True

  Statistical information is being analyzed ...
