Hi, I don't know when to use dictionaries ARUCO_MIP_36h12 and ARUCO. Which one for the aruco.DICT_4X4_1000 dictionary in Python-Opencv or which one should i use for aruco.DICT_7X7_50. What I need is the priority of fast recognition in low resolution on mobile phones. I would appreciate if you can provide further information on which dictionary should be used for fast recognition and which dictionary should be used for high accuracy. thanks.

Hi, for high accuracy you should use ARUCO_MIP_36h12 as it as the best error correction rate (12 bit distance). The aruco.DICT_4X4_1000 in opencv is the same as this https://github.com/damianofalcioni/js-aruco2/blob/master/src/dictionaries/aruco_4x4_1000.js . You can see other dictionary in this folder and the name is quite explicit. The aruco.DICT_7X7_50 has not been imported.

Hope this helps
