背景

如果要在rviz上可视化一般包括以下两个步骤:

  1. 定义这个图形的消息类型(一般可以使用rviz自带的消息类型或第三方库所提供的消息类型),通过话题发布出来。
  2. 在rviz中根据接收到消息将图形绘制出来。

第三方库主要有以下几种:

  • jsk_rviz_plugins
  • gridmap_rviz_plugins
  • autoware

博主使用的是jsk_rviz_plugins库,它是一个提供原始 rviz 插件的包。当启动 rviz 即可使用这些 rviz 插件、面板和工具。官方的阅读文档:https://jsk-visualization.readthedocs.io/en/latest/jsk_rviz_plugins/index.html
官方Github链接:https://github.com/jsk-ros-pkg/jsk_visualization

报错

博主在可视化jsk_recognition_msgs/BoundingBoxArray(3D 边界框)的时候,遇到了以下错误:

Error: The plugin for class ‘jsk_rviz_plugin/BoundingBoxArray’ failed to load.

解决

解决方法是需要安装相应的库与插件,打开终端输入以下命令:

# 更新软件源列表
sudo apt-get update
# 根据自己的ROS版本选择对应的指令
# ubuntu16.04:kinetic
sudo apt-get install ros-kinetic-jsk-recognition-msgs
sudo apt-get install ros-kinetic-jsk-rviz-plugins
# ubuntu18.04:melodic
sudo apt-get install ros-melodic-jsk-recognition-msgs
sudo apt-get install ros-melodic-jsk-rviz-plugins
# ubuntu20.04:noetic
sudo apt-get install ros-noetic-jsk-recognition-msgs
sudo apt-get install ros-noetic-jsk-rviz-plugins

安装好后,又遇到了rviz无法显示,state为error的报错,后来检查rviz文件发现:Class: jsk_rviz_plugin/BoundingBoxArray下面的Topic和Fixed Frame字段设置错误,根据自己的代码修改成相对应的Topic和Frame即可。(遇到报错一定要仔细检查!)
