Hi! can someone explain me the concept of MultiThreading in ros? I read http://wiki.ros.org/roscpp/Overview/C... but I've some doubts. Can I use it to makes my execution code faster? How can I manage the relation between Sub/Pub with MultiThreading? Thanks to all!!!

Thanks man!! I've another question. Is there a method to discover the distance between my image/object and my kinect? Thank you :)

Hi guys. I'm working with my kinect to extract point clouds. So I run at first openni_launch and after i run : rosrun pcl_ros pointcloud_to_pcd input:=/camera/depth_registered/points So after this, ROS saves every point clouds that kinect gets. SO my question is: how can I extract data from a PCD? I want to extract fields about sensor_msgs/PointField[]. It exists another method to get every information about a PCD file? thanks to all!

Hi everybody, I occured a problem during the installation of Humanoid_Navigation package. Following this guide http://wiki.ros.org/humanoid_navigati... when I do "catkin_make", something goes wrong:

Could not find a package configuration file provided by "Eigen" with any of the following names:

Add the installation prefix of "Eigen" to CMAKE_PREFIX_PATH or set "Eigen_DIR" to a directory containing one of the above files. If "Eigen" provides a separate development package or SDK, be sure it has been installed.

Can someone help me? Thanks to all!
