Web21 de mar. de 2024 · Generating ArUco markers in OpenCV. We can generate these markers very easily using OpenCV. The aruco module in OpenCV has a total of 25 predefined dictionaries of markers. All the markers in a dictionary contain the same number of blocks or bits(4×4, 5×5, 6×6 or 7×7), and each dictionary contains a fixed number of … WebNote that the OpenCV marker dictionary may have different marker IDs than the original Aruco dictionary, so the ID you have for a marker may not be what this plugin sees. Therefore, I recommend logging the IDs found in a frame through a C# script and showing your markers to the camera to get the ID they are recognised as.
