i have searched the sensor list on the: http://wiki.ros.org/Sensors#Cameras
but i want know how to install it if i know the Source: git https://github.com/bosch-ros-pkg/usb_... (branch: master)
thanks a lot
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.
Hi,
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 https://github.com/bosch-ros-pkg/usb_cam.git
$ 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
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
udooer@udoo:~$ rosrun usb_cam usb_cam_node
