rviz 作为接收侧,在接收visualization_msgs::Marker topic时,由于rviz内部Marker没有删除机制,所以内存增长导致Out of memory,具体log如下: terminate called after throwing an instance of 'Ogre::InternalErrorException' what(): OGRE EXCEPTION(7:InternalErrorException): Index Buffer: Out of memory in GLHardware...
2. nav_msgs/Path 这个功能是利用rviz中的Path类型实现的,只需要发布nav_msgs/Path类型的消息,然后在rviz上订阅该消息就可以显示轨迹路径。而nav_msgs/Path类型的数据很简单,就是一个位姿的集合。navigation功能包集中显示规划路径用的就是这个东西。 这个有点像Marker中的序列和点集一样,需要维护一个数组。在rviz...
