use realsense d435i, but did not detect anything about apriltag_ros HOT 4 CLOSED

Please check with the apriltag_demo from the apriltag library first before reporting such issues to the ROS node.

Looking at the image, my best guess is that your fingers are interfering with the edge detection.

I can detect using your launch file, but I want to use Python to write the launch file. However, I'm not sure how to implement the following parameters in Python

    - pkg: apriltag_ros
      plugin: AprilTagNode
      name: apriltag
      namespace: apriltag
      remap:
      - from: /apriltag/image_rect
        to: /v4l2/image_rect
      - from: /apriltag/camera_info
        to: /v4l2/camera_info
      param:
      - from: $(find-pkg-share apriltag_ros)/cfg/tags_36h11.yaml
      extra_arg:
      - name: use_intra_process_comms
        value: "True"

That's a bit out of scope for this issue and this repo is not the best place to ask common ROS questions.

Just googling for "ros2 launch files parameters" gives me:

• https://roboticscasual.com/tutorial-ros2-launch-files-all-you-need-to-know/
• https://roboticsbackend.com/ros2-launch-file-example/
• https://docs.ros.org/en/foxy/How-To-Guides/Launch-file-different-formats.html

If this is still unclear or you have a very specific problem with launch files, then I suggest asking your question at https://robotics.stackexchange.com.

You mentioned that your original issue with the tag detection has been solved. I am going to close this issue.

ok, I will try another method.
