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.

when i try to run roslaunch ar_sys single_board.launch

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

You've been asking this question a lot:

The reason that you probably haven't gotten any good answers is because the questions are not good. (Your English is fine.) Please see the guidelines for asking a question

running the usb_cam node should provide ROS topics with images from your camera ("define it to ROS")

From your previous post it looks like you tried to run the usb_cam node. Please try this again, but this time include:

The full link to the tutorial or previous questions that you're following (linking to ros.org is not useful)
The exact commands for all of the nodes that you're running
The FULL output form the usb_cam node
Your observations, and what you expect to happen.
