show the image/video

$ rosrun image_view image_view image:=/image_raw
[ INFO] [1539699406.532269649]: Using transport "raw"And now, you can see a window and show the camera video.

usb-camera

install the usb-camera

$ apt-cache search ros-kinetic-usb
ros-kinetic-usb-cam - A ROS Driver for V4L USB Cameras

install it:

$ sudo apt-get install ros-kinetic-usb-cam

update the ros pack env.

$ rospack profile

Test the usb-camera

as you known, begin run an ros node or launch, just start roscore.

$roscore
