首先更改:~/video_ws/build里的 CMakeCache.txt和Makefile 将路径名字修改为你自己的。vi下批量替换命令为 :%s/a/b/g (意思是把a换成b) 修改之后 回到工作空间, 执行 rosdep install --from-paths src --ignore-src --rosdistro=noetic -y 随后catkin_make 第一种方法: roslaunch usb_cam usb_cam-test.launch (不需要运行roscore) 第二种方法: rosrun usb_cam img_publisher #put vedio rosrun usb_cam img_viewer #get video 网络流: (需要配置一个文件) 1. roscd web_video_server 2. sudo mkdir launch 3. cp ~/video_ws/web_video.launch /opt/ros/noetic/share/web_video_server/launch (根据自己路径改变) roslaunch web_video_server web_video.launch 待补充 # new 新方式 ``` # 适用于ros noetic 环境 : Ubuntu20.04 sudo apt install ros-noetic-cv-camera # rosparam set cv_camera/device_id 0 # rosrun cv_camera cv_camera_node # rosrun web_video_server web_video_server ``` # 待补充
