01 ros框架下的摄像头调用方法

基础步骤：

1.配置工作环境

构建catkin_ws工作空间（预先建立相应文件夹）

cd ~/catkin_ws/src

安装和编译usb_cam

git clone https://github.com/bosch-ros-pkg/usb_cam usb_cam
cd usb_cam
mkdir build 
cd build 
cmake ..
make 

2.启动和测试

roscore //启动ros

roslaunch usb_cam usb_cam-test.launch //在launch文件所在文件夹下运行

3.报错解决方案

错误1：v4l2-ctl: not found

sudo apt-get install v4l-utils

错误2：[usb_cam-test.launch] is neither a launch file in package [usb_cam] nor is [usb_cam] a launch file name      The traceback for the exception was written to the log file2

source ~/catkin_ws/devel/setup.bash //要在运行usb_cam usb_cam-test.launch 命令前执行
