Hi, I need to save vector of geometry_msgs::Point to a file because I need to reuse it in a future. I have already done some research (e.g. tried this http://stackoverflow.com/questions/24... ) but nothing worked...any ideas? Is that even possible?
Thanks in advance, JP
I agree with @dornhege. I would first try to use rosbag (maybe create a custom message with a list of points, or store all points as messages on a single topic). Alternatively, you can directly write rosbags from your program using the rosbag API [1,2]. If that doesn't suit you either, you can directly serialize the individual messages using the message serialization facilities [3]. Lastly, you are always free to just write your own specialized serialization. After all, a Point message is just 3 floats.

Do you need to write that from code? ROS tools like rosbag or rostopic echo enable you to dump messages to files easily. There is also the rosbag api.
If u want i can give u a cpp file that saves subsribed topic to CSV file
