I successfully completed the AprilTag Tutorial from Documentation for RealSense camera. I successfully ran the following code: “ros2 launch isaac_ros_examples isaac_ros_examples.launch.py launch_fragments:=realsense_mono_rect,apriltag” which clearly states that “Node was started”, but I cannot detect any AprilTag by running the following command ros2 topic echo /tag_detections. So, I was wondering If i have to use any specific apriltag family, id, and size? My camera model is: The Depth Camera D435i
Welcome to join to the Isaac ROS forum.
First question: Have you correctly installed the Realsense driver and set up your device following our documentation? Isaac ROS RealSense Setup — isaac_ros_docs documentation
Isaac ROS detects all types of apriltags in this image and documents them. https://april.eecs.umich.edu/software/apriltag.html
The demo you are running loads isaac_ros_apriltag.launch.py, which is configured for Apriltag with a size of 0.22m.
I’m also experiencing the same issue.
I think that the camera image topics /realsense2_camera/color/image_raw and /realsense2_camera/color/camera_info are not being correctly remapped to /image_rect and /camera_info_rect by the command
ros2 launch isaac_ros_examples isaac_ros_examples.launch.py launch_fragments:=realsense_mono_rect,apriltag.
