CSV Files for Ground Truth

[MostafaOsman144]

I can't find the Groundtruth CSV files of any bagfiles except for GPS-RTK-20180719. In another issue, it is mentioned that the ground truth is in nemea_sentence, how can I convert the string inside these messages to xyz coordinates similar to those in the CSV files ?

There's only one CSV file, you need to generate the others by yourself. With:

  <!-- Magellan ProFlex 500 GNSS Receiver -->
  <node pkg="nmea_navsat_driver" type="nmea_topic_driver" name="nmea_topic_driver" output="screen"/>
  <node pkg="gps_common" type="utm_odometry_node" name="utm_odometry_node"/>
  <node pkg="magellan_proflex500_driver" type="magellan_proflex500_driver" name="magellan_proflex500_driver"/>

you can get GT position from /magellan_proflex500_driver/marker_array and easy to save as CSV file.

Ok, I find it now, thank you.

When I launch the launch file and play bag, but I cannot echo /fix or /magellan_proflex500_driver/marker_array data through the ros topic,how to deal with?

Hi, if you are using this https://github.com/epan-utbm/utbm_robocar_dataset/tree/baselines/launch, you should be able to see:

Thank you very much!

HI, @yzrobot

When i launch the following

There's only one CSV file, you need to generate the others by yourself. With:

  <!-- Magellan ProFlex 500 GNSS Receiver -->
  <node pkg="nmea_navsat_driver" type="nmea_topic_driver" name="nmea_topic_driver" output="screen"/>
  <node pkg="gps_common" type="utm_odometry_node" name="utm_odometry_node"/>
  <node pkg="magellan_proflex500_driver" type="magellan_proflex500_driver" name="magellan_proflex500_driver"/>

you can get GT position from /magellan_proflex500_driver/marker_array and easy to save as CSV file.

There is an error called
"ERROR: cannot launch node of type [magellan_proflex500_driver/magellan_proflex500_driver]: magellan_proflex500_driver
ROS path [0]=/opt/ros/melodic/share/ros
ROS path [1]=/home/cyz/workspace/catkin_main/src
ROS path [2]=/opt/ros/melodic/share"

so the node is not actived. What may be the problem ?

Looking forward to your help;)

[yzrobot]

Hi, do you have the corresponding driver installed? Please check here and here.

[YangSiri]

Yes, @yzrobot

The magellan_proflex500_driver is built as well as the others.
