walking机器人仿真教程-应用-多点导航结合录像功能实现移动录像

说明:

• 介绍如何使用多点导航结合录像功能实现移动录像
• 想法: 可以定期在不同地点拍一段留存视频
• 实现原理: 通过航点编辑器设置航点文件增加操作项，再通过python3导航脚本读取航点文件，获取航点进行导航，根据操作字段operate判断为录像动作，从而启动录像程序.

步骤:

• 加载gazebo

. /usr/share/gazebo/setup.bash 

• 启动仿真

ros2 launch walking_application house_world_v2.launch.py

• gazebo效果：

• rviz效果：　

• 摄像头效果：　

• 设计航点
• 利用walking_navigation多点导航面板, 参考和目标点设置工具walkingGoal,参考,设定航点并保存航点

• 保存文件到目录并命名:/home/ubuntu/waypoints/house_waypoints_video.json
• 再利用航点编辑工具,设置航点操作为TakeVideo

• 保存文件到目录并命名:/home/ubuntu/waypoints/house_waypoints_video_ed.json
• 启动导航

ros2 run walking_application run_inspection_v5.py

• 文件已经默认指定航点文件为/home/ubuntu/waypoints/house_waypoints_video_ed.json
• 执行效果：　

$ ros2 run walking_application run_inspection_v5.py

• 执行之后，自动在房间内导航，到达一个航点之后，会启动录像程序
• 视频保存的目录位于/home/ubuntu/Videos/下，命名类似：video_202205272005.avi
• 进入视频目录，可以使用命令vlc video_202205272005.avi查看视频
• 使用的航点文件位于/home/ubuntu/waypoints/house_waypoints_video_ed.json
