使用Webviz工具有两种方式，需要特别注意的是，两者方式都需要下载Chrome浏览器
直接进入官方在线网站 https://webviz.io/app/ （由于网站服务器在国外，国内使用体验不佳）
在GitHub上下载开源项目进行本地构建（可参考博客Webviz - ROS可视化开源项目 - 本地构建教程）
Webviz支持两种可视化的方式：ROS bag files 回放 和 ROS bridge 实时监测。
第一步，获得ROS bag文件：
#运行ROS
……
#查看当前所有topic
rostopic list -v
#记录指定的topic
rosbag record /topic1 /topic2
#记录所有的topic
rosbag record -a
第二步，将ROS bag文件拖放到Webviz网站界面：
第一步，安装ROS bridge：
sudo apt-get install ros-<rosdistro>-rosbridge-suite
第二步，启动ROS bridge：
启动rosbridge后，默认在9090端口建立WebSocket连接（与Webviz默认端口一致，不需要更改）
source /opt/ros/<rosdistro>/setup.bash
roslaunch rosbridge_server rosbridge_websocket.launch
第三步，启动您的ROS程序：
点击设置按钮 ? 点击
Change panel? 根据需要选择功能窗口即可
点击设置按钮 ? 点击
import/export panel setting? 选择copy或 粘贴自定义配置 ? 选择Apply将设置应用到网站中（需要注意的是，如果要改变整体布局，请选择下图右上角的设置按钮；若要改变单个窗口布局，请选择上图的设置按钮）
下面是一个包含常用功能窗口的配置，可通过上面提到的方法导入到自己的面板上进行预览和进一步修改
