There is two things you should try :

First : I see that you type image:/usb_cam but It should be for remapping image:=/usb_cam with the "=" !

Then I did not see what you have set for your camera since it seems that you have paste the answer of you terminal right after you camera:=/ command

So to complete your command line do a rostopic list as follow

vvittori@delos:~/ros_workspace/stereo_robust_matching$rostopic list /camera/camera_info /camera/image_raw /camera/image_raw/compressed /camera/image_raw/compressed/parameter_descriptions /camera/image_raw/compressed/parameter_updates /camera/image_raw/theora /camera/image_raw/theora/parameter_descriptions /camera/image_raw/theora/parameter_updates /cameraUEYE_node/parameter_descriptions /cameraUEYE_node/parameter_updates /rosout /rosout_agg  and then set the command line as follow (in my exemple /camera/image_raw is my image and /camera is my camera name ) rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.108 image:=/camera/image_raw camera:=/camera  So for you it should be I gess rosrun camera_calibration cameracalibrator.py --size 10x7 --square 0.022 image:=/usb_cam/image_raw camera:=/usb_cam  Hi, There is two things you should try : First : I see that you type image:/usb_cam but It should be for remapping image:=/usb_cam with the "=" !

/camera/camera_info
/camera/image_raw
/camera/image_raw/compressed
/camera/image_raw/compressed/parameter_descriptions
/camera/image_raw/theora
/camera/image_raw/theora/parameter_descriptions
/cameraUEYE_node/parameter_descriptions
/rosout
/rosout_agg


and then set the command line as follow (in my exemple /camera/image_raw is my image and /camera is my camera name )

rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.108 image:=/camera/image_raw camera:=/camera


So for you it should be I gess

rosrun camera_calibration cameracalibrator.py --size 10x7 --square 0.022  image:=/usb_cam/image_raw camera:=/usb_cam
