问题描述
我需要对 ROS 项目进行姿势估计，并且我正在使用 ildoonet 的 tf-openpose，因为它不需要沉重的 NVIDIA GPU 即可获得不错的帧速率。我找到了一个很好的 ROS 包装器 here，但碰巧其中一个依赖项，即 ros_video_recorder 的 GitHub 页面被删除了。我附上了终端输出，附上错误截图，方便阅读。有什么替代方法吗？主要的 tf-openpose 存储库也被删除了，但是有很多人分叉了它来添加他们的功能，所以这不是问题，但我找不到任何关于此的信息。任何和所有帮助将不胜感激。
当我正常启动网络摄像头姿势估计器时，它可以工作，只是 roslaunch 有问题。
我使用 Ubuntu 18.04 和 ROS 1 Melodic。
