Hi, my name is Matheus Conceição, and I work with the bluerov2, now I try to save data of sensors of bluerov2, I can see all sensors, but the camera when I try to save the data, have a “bag” (Command : rosbag record “topic”) with 1 GB or more, and have just 4 seconds of data, I would like to know if anybody compress the data of camera or if can be compressed, I would like to know-how.
I read the data with Mavros, and I have the command that shows the data on a topic, and I would like to save the data of the topic compressed and after I would like to see the image again.
the commands that I used to see topics are this:
on the first terminal:
roslaunch bluerov_ros_playground bluerov2_node.launch bluerov_node_device:=udp:localhost:14550
on the second terminal:
roslaunch bluerov_ros_playground user_mav.launch
after you can see the topics with command “rostopic list” and chose what command you would like to see use command "rostopic echo “topic” ", I used this commands to see data and save on bag, and I would like to use this commands to see data of camera and
before you use these commands, you need to install the BlueRov-ROS-playground on this link: https://github.com/patrickelectric/bluerov_ros_playground 1 .
