You can also use sudo apt-get install ros-kinetic-usb-cam, replacing kinetic with your desired distribution. This will install the package to your /opt/ros/kinetic/lib directory.

These days (sometime after ROS Indigo era), binary of usb_cam has been released, so I think this is more preferable answer.

Right now, Like you have mentioned the usb_cam has source code for wet build (catkin build). you just need to do the following to build it from source. (Note: I assume you are using ROS hydro or Indigo, It should work on groovy as well may be you can try it). But all that said, here you go:

$ mkdir -p ~/catkin-ws/src

$ cd ~/catkin-ws/src

$ git clone

$ cd ..

$ catkin_make

$ source ~/catkin-ws/devel/setup.bash

after the above you can verify using ..

$ roscd usb_cam

roscore on a new terminal $ roscore

and then in the terminal where you $ source 'd your usb_cam code run:

$ rosrun usb_cam usb_cam_node

Make sure you have your camera connected, before running the above command!!! you view the captured image on rviz,

$ rosrun rviz rviz

hope this helps. mk

It worked for me as well. But I would like to connect to my usb cam that i have connected externally instead of my laptop's internal webcam... is there any way I could do that.???

To connect external cam. Locate the usb_cam-test.launch file in folder cd ~/catkin-ws/src/usb_cam/launch Change <param name="video_device" value="/dev/video0" /> to <param name="video_device" value="/dev/video1" /> From cd ~/catkin-ws/src/usb_cam/launch.Run roslaunch usb_cam-test.launch

when I run $ rosrun usb_cam usb_cam_node, I got an error [ERROR] [1488942795.328150657]: outbuf size mismatch. pic_size: 814080 bufsize: 614400. But if I run roslaunch usb_cam-test.launch directly, I could get the video. How could I fix that error?

Well I have problem directly using catkin_make, and I solve it by type sudo apt-get install ros-kinetic-usb-cam first and then catkin_make again.

There are some errors about comand "$ rosrun usb_cam usb_cam_node" . It shows error message like the following. I have tried to open my camera (logitech C920) with guvcview successfully. However,it still can't work on ROS . using indigo ; workspace catkin

Thank a lot.

udooer@udoo:~$ rosrun usb_cam usb_cam_node
