Getting UVC working with Raspberry Pi

Steps

1. install uvc stuff.

   sudo apt update
   sudo apt install -y libuvc-dev guvcview cheese v4l-utils
   # sudo apt install -y uvccapture uvcdynctrl
   

2. try guvcview or cheese to see if you can see video output(may need to install):

   # cheese # only need to try one command
   guvcview
   

3. (optional, seems already done, perhaps by previous step) add yourself to video group

   sudo usermod -a -G video $(whoami)
   

   1. Logout & login again , check if your vboxusers displays in this command

   groups
   

4. (optional, seems already done, perhaps by previous step) copy rules from idealab_ros_tools to rules folder (according to this ref)

cd ~/code/code_idealab_ros/src
sudo cp 99-uvc-c930.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && udevadm trigger
sudo reboot

1. get workspace prepared with dependencies:

   cd ~
   
   git clone https://github.com/ros-drivers/libuvc_ros
   cd libuvc_ros
   cp -r libuvc_camera ~/code/code_idealab_ros/src
   cp -r libuvc_ros ~/code/code_idealab_ros/src
   
   cd ~
   
   git clone https://github.com/ros/nodelet_core
   cd nodelet_core
   cp -r nodelet ~/code/code_idealab_ros/src
   cp -r nodelet_core ~/code/code_idealab_ros/src
   
   git clone https://github.com/ros/bond_core
   cd bond_core
   cp -r * ~/code/code_idealab_ros/src
   
   cd ~
   
   cd code_idealab_ros/
   catkin_make
   

2. identify desired video device:

v4l2-ctl --list-devices

1. start roscore on master uri

2. run node

rosrun libuvc_camera camera_node
