I am trying to use ArUco library with opencv. I have installed OpenCV 3.1 on ubuntu, opencv contrib and compiled both. When I do help(cv2.aruco), the functions are not listed. This is the output -

Help on module cv2.aruco in cv2:

NAME cv2.aruco

FILE (built-in)

DATA DICT_4X4_100 = 1 DICT_4X4_1000 = 3 DICT_4X4_250 = 2 DICT_4X4_50 = 0 DICT_5X5_100 = 5 DICT_5X5_1000 = 7 DICT_5X5_250 = 6 DICT_5X5_50 = 4 DICT_6X6_100 = 9 DICT_6X6_1000 = 11 DICT_6X6_250 = 10 DICT_6X6_50 = 8 DICT_7X7_100 = 13 DICT_7X7_1000 = 15 DICT_7X7_250 = 14 DICT_7X7_50 = 12 DICT_ARUCO_ORIGINAL = 16

Further, if I try using those functions, I hit errors like this - aruco_dict = aruco.Dictionary_get(aruco.DICT_5X5_250) AttributeError: 'module' object has no attribute 'Dictionary_get'

How do I generate markers and detect the same in python?
