The ZED node publishes both original and stereo rectified (aligned) left and right images. Note: If you haven’t yet configured your own RVIZ2 interface, you can find a detailed tutorial. If you are using a ZED2i camera: $ roslaunch zed_display_rviz display_ If you are using a ZED2 camera: $ roslaunch zed_display_rviz display_ If you are using a ZED-M camera: $ roslaunch zed_display_rviz display_ Launch the ZED wrapper along with RVIZ using the following command (installing the is required): $ ros2 launch zed_display_rviz display_ Using RVIZ2, you can visualize the left and right images acquired by the ZED cameras, the depth image and the 3D colored point cloud. RVIZ2 is a useful visualization tool in ROS2. For full descriptions of each parameter, follow the. Note : You can set your own configurations modifying the parameters in the files common.yaml, zed.yaml, zedm.yaml, zed2.yaml, and zed2i.yaml available in the folder zed_wrapper/config. Basically, I am trying to use this compilation for my best HRMS software in Kolkata and related things. The, ,, and are three Python scripts that automatically start the ZED node using “”, loading the parameters from the correct “YAML files” and creating the camera model from the “URDF file” that is automatically created from a configuration file. To start the ZED node, open a terminal and use the CLI command ros2 launch : ![]() Note: If you are using a different console interface like zsh, you have to change the source command as follows: echo source $(pwd)/install/local_setup.zsh > ~/.zshrc and source ~/.zshrc. This is true only for all the files that don’t need to be compiled (Python launch scripts, YAML configurations, etc). Using symlinks allows you to modify them in your workspace, reflecting the modification during the next executions without the needing to issue a new colcon build command. Each package in ROS2 must be installed and all the files used by the nodes must be copied into the installation folders. It allows to use symlinks instead of copying files to the ROS2 folders during the installation, where possible. Note: The option -symlink-install is very important. $ echo source $(pwd)/install/local_setup.bash > ~/.bashrc $ colcon build -symlink-install -cmake-args=-DCMAKE_BUILD_TYPE=Release $ rosdep install -from-paths src -ignore-src -r -y To install the zed_ros2_wrapper, open a bash terminal, clone the package from Github, and build it: $ cd ~/ros2_ws/src/ #use your current ros2 workspace folder Note: If you haven’t set up your colcon workspace yet, please follow this. Pose tracking: Position and orientation of the camera fixed and fused with IMU data (ZED-M and ZED2 only).Visual odometry: Position and orientation of the camera.Left and right rectified/unrectified images.It provides access to the following data: The lets you use the ZED stereo cameras with the second version of ROS. I am writing down all the necessary things related to zed ros2 wrapper. ![]()
