hi. i want to run ar_sys package . But i dont know that how i will define my laptop's camera to ROS . And i dont know how can i pass the proper launcher parameters (see launch files for details) to meet my camera device, calibration URI, pointing to the correct board configuration.

May u explain that with picture or video or explain it here ? Thanks.

There is this Error :

terminate called after throwing an instance of 'std::runtime_error'
  what():  pixel format unavailable
[ INFO] [1461717403.333087263]: ArSys node started with marker size of 0.050000 m and board configuration: /opt/ros/indigo/share/ar_sys/data/single/board.yml

hi. i am beginner. i wanna run ar_sys package but i have a few problems.

i have usb cam or can i do that with my laptop's camera ?

Firstly :

 "Fixed Frame No tf data. Actual error: Fixed Frame [world] does not exist"

probably my camera is not define to ROS. How can i do that ?

Secondly : i try to run this line :

rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 0.0 map my_frame 100

But i have this error:

Fixed Frame [world] does not exist

Thirdly : Have i to use special camera for ar_sys package ? (like we have to use lidar scanner in hector slam.)
