  Detailed description I use apriltags for UAV(PX4) position. This priject ompile successfully ,when I executive program appear this problem:

==================

./tracker Basic marker detection for drone localization Usage: tracker [params]

-c
    Camera intrinsic parameters. Needed for marker pose
--ci (value:0)
    Camera id if input doesnt come from video (-v)
--cp
    Camera position and rotation file. Default is camra at origin pointing up, y oppoite of N, x opposite of E
-d
    dictionary: DICT_4X4_50=0, DICT_4X4_100=1, DICT_4X4_250=2 DICT_4X4_1000=3, DICT_5X5_50=4, DICT_5X5_100=5, DICT_5X5_250=6, DICT_5X5_1000=7, DICT_6X6_50=8, DICT_6X6_100=9, DICT_6X6_250=10, DICT_6X6_1000=11, DICT_7X7_50=12,DICT_7X7_100=13, DICT_7X7_250=14, DICT_7X7_1000=15, DICT_ARUCO_ORIGINAL = 16
--db (value:57600)
    Baudrate for Mavlink device
--dp
    File of marker detector parameters
--dv (value:/dev/ttyUSB0)
    Device for Mavlink
-r
    show rejected candidates too

./tracker -v /dev/video0 -d DICT_4X4_100=1 --db 57600 --dv /dev/ttyS0

[berak]

since this is using cv::CommandLineParser, you have to call your program like:

./tracker --ci=0 -d=1 --db=57600 --dv=/dev/ttyS0

(you're missing the = between argument name and value, also the DICT is an enum)

Thank you very much.Now the project run successfuly. @berak
