saltybot_aruco_detect 0.1.0 ArUco marker detection for docking alignment (Issue #627). Detects all DICT_4X4_50 markers from RealSense D435i RGB, estimates 6-DOF pose with estimatePoseSingleMarkers, publishes PoseArray on /saltybot/aruco/markers and closest dock-candidate marker on /saltybot/aruco/dock_target (PoseStamped) with RViz MarkerArray and JSON status. sl-perception MIT ament_python rclpy std_msgs sensor_msgs geometry_msgs visualization_msgs cv_bridge python3-numpy python3-opencv ament_copyright ament_flake8 ament_pep257 python3-pytest ament_python
