2020-06-10 04:00:49 -0500 marked best answer Transform NavSatFix to Tf

This is probably a dumb question.

I am working with the Kitti dataset. I am trying to express the content of the topic /kitti/oxts/gps/fix (NavSatFix - lat, long, alt) in the reference world reference system of Tf (x, y, z).

Do you know a way to do it? Thanks

Is there a difference in terms of efficiency? For instance, is image_transport::Subscriber "faster" than ros::Subscriber

2017-03-26 08:53:49 -0500 asked a question roscore does not initialize

Hey guys,

I'm new to ROS. If I run roscore, it does not initialize, it just gets stuck. If I run strace roscore, after a certain point, I keep seeing the following forever:

select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)

Concerning the environmental variables, I have:

ROS_ROOT=/opt/ros/kinetic/share/ros
ROS_PACKAGE_PATH=/home/filippo/catkin_ws/src:/opt/ros/kinetic/share
ROS_MASTER_URI=http://localhost:11311
ROS_HOSTNAME=localhost
ROSLISP_PACKAGE_DIRECTORIES=/home/filippo/catkin_ws/devel/share/common-lisp
ROS_DISTRO=kinetic
ROS_ETC_DIR=/opt/ros/kinetic/etc/ros

The console output is:

Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.
