在Ubuntu 22.04中安装ROS 2和`usb_cam`功能包的步骤如下:
1. 添加ROS 2源:
```
sudo apt update
sudo apt install curl gnupg2 lsb-release
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -
sudo sh -c 'echo "deb [arch=$(dpkg --print-architecture)] http://packages.ros.org/ros2/ubuntu $(lsb_release -cs) main" > /etc/apt/sources.list.d/ros2-latest.list'
```
2. 安装ROS 2:
```
sudo apt update
sudo apt install ros-foxy-desktop
```
3. 安装依赖项:
```
sudo apt install ros-foxy-ros-base ros-foxy-v4l2-camera
```
4. 下载`usb_cam`功能包:
```
mkdir -p ~/ros2_ws/src
cd ~/ros2_ws/src
git clone https://github.com/ros-drivers/usb_cam.git
```
5. 编译`usb_cam`功能包:
```
cd ~/ros2_ws
colcon build --symlink-install
```
6. 开启摄像头:
```
ros2 run v4l2_camera v4l2_camera_node --ros-args --remap __node:=usb_cam
```
7. 打开新终端,查看摄像头:
```
ros2 run image_tools showimage --ros-args --remap image:=/usb_cam/image_raw
```
这样就可以在ROS 2中使用`usb_cam`功能包了。
