By using these markers, you can find the real-world coordinates of a marker, including depth. 3 days ago · Prev Tutorial: Calibration with ArUco and ChArUco This is a compilation of questions that can be useful for those that want to use the aruco module. It subscribes to camera information and image topics, performs marker detection using OpenCV's ArUco library, and estimates the pose of a cube with ArUco markers. According to the drawAxis function, the positive direction is away f Accurate camera pose estimation is crucial for various applications in robotics and computer vision, enabling precise navigation and interaction with the environment. If you want to estimate one pose from a set of markers, use ArUco Boards (see the Detection of ArUco Boards tutorial). pmhp qdstie ufj juxhgu veozbyy ulcrq doblqah ghx dagh ccnvjbl
