Hi, I am using ORBBEC astra camera for detection of apriltag using the apriltag_ros package and unable to visualize the apriltag. I followed the april_tag ros tutorial link text. following are the verison and node used :

  1. ros-melodic-desktop-full
  2. apriltag_ros package
  3. tag_family: tag16h5
  4. scaled the apriltag : tag16_05_00000.png and printed tag size: 0.148m (edge length)
  5. Astra camera publishing the /camera/rgb/image_rect_color and /camera/rgb/camera_info at 30Hz

Changes made in tag.yaml:
- standalone_tags: [ {id: 0, size: 0.148} ]

Changes made in settings.yaml file in config of apriltag_ros repo:
- tag_family: 'tag16h5'

Then after this changes the following command to run the apriltag_ros node:

roslaunch apriltag_ros continuous_detection.launch camera/image_rect:=camera/rgb/image_rect_color camera/camera_info:=camera/rgb/camera_info

following is the output:

... logging to /root/.ros/log/299831bc-a5ee-11ec-9486-1c1bb5e2fe69/roslaunch-IKIM12-1410.log Checking log directory for disk usage. This may take a while. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
