Hi,

I am a newbie to ROS and I want to use some of the built-in filters to process the laser scan.

I installed the filters package before and I double checked today by typing: sudo apt-get install ros-indigo-laser-filters

it said:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
ros-indigo-filters is already the newest version.
ros-indigo-filters set to manually installed.
The following packages were automatically installed and are no longer required:
  libgcal0 linux-headers-3.13.0-32 linux-headers-3.13.0-32-generic
  linux-image-3.13.0-32-generic linux-image-extra-3.13.0-32-generic
  ros-indigo-shape-tools
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 20 not upgraded.

So the filters should have been installed right?

However, when I open the laser_filters folder in opt/ros/indigo/shared/, there are only a cmake folder and two xml files. From the tutorial there should be a "examples" folder inside the laser_filter folder.

Can anyone tell me if the laser_filters package was correctly installed? Where can I find the package?

Thanks in advance.

Clone https://github.com/ros-perception/las... (proper distro) into your src if you want to play around with the source code. You'll need do a catkin_make of your catkin folder in the terminal to use them.
