You can also place digital content based on the presence and transform of a physical image. Marker Data Pose . However, the first step is to detect the virtual ArUco marker. I’ve Thanks Benjamin, I’ve recreated the Unity project from scratch again and followed the instructions with similar results. Identical QR codes will be treated as separate targets and reported individually. Tools. Is this Anyone have experience using ArUco markers for quick alignment of real-world element positioning with virtual environment positioning as seen in this video at 6:20? I would love to How to Detect Markers with OpenCV and ZED in Unity. Rated by In order to be able to track markers you need to calibrate your camera, i. By attaching the camera, we detect the ArUco marker transform information when receiving video images. First, we create a 3D model to combine an external camera with Quest 2 or Quest 3. Marker Understanding Overview. The idea would be to place 3 AR Markers in a triangular shape and when all 3 are detected draw a cube in the middle. For a project, I placed ArUco markers on cubes, placed in front of a camera. Decentralization. See Creating ArUco markers for Marker-Based Scene Alignment. To implement this, we used the OpenCV aruco module, and created a C++ native plugin for unity to communicate between the C++ OpenCV code, and our Unity C# code. 3D.
