Hey,

I am very new to the ROS and 3D LIDAR and today I got the Velodyne VLP-16 LIDAR from our group, somehow I can not let it working properly. Here is some detail description of my problem:

I am using ROS indigo. First we I did is to use the sample data in the flash drive and uses some ROS command ( http://www.pcl-users.org/Convert-pcap... ) to convert the data from .pcap to .pcd format in order to run some PCL functions. The sample data was from HDL32E LIDAR and I had no problem of this part since the velodyne_pointcloud folder has the 32e_points.launch file.

Next step, I saved a .pcap file from the VLP-16 LIDAR and wanted to repeat the same procedure. Somehow this time I could not make it working since there is no VLP16_points.launch file in the velodyne_pointcloud folder!!! Then I searched online and from Github I saw the newest folder of the Velodyne driver do include the VLP16_points.launch, so I wonder what procedure should I do to upgrade the Velodyne related files to the newest version?

Since I am really new to this area so all suggestions will be highly appreciated!

There has not been an Indigo release of the Velodyne packages in over a year: https://github.com/ros-drivers/velody...

To get the newer features (VLP-16 support) you will have to compile from source. Clone the velodyne repository into your workspace. Then build your workspace with catkin_make.

That is correct. We are working on a new Indigo release that will include VLP-16 support and some other items, but it's not quite ready to go yet. Soon, I hope.

I am using one from github but am curious what kind of issues in the git repo, if any, prevent it from being released.

Insufficient testing and documentation, and not enough time in my schedule. If you wish to help with the first two, please let me know.

I can help with that, I am using velodyne 32 and two devices of velodyne 16.

That would be great. The code is nearly ready at this point, but the docs need a good review to bring everything up to date.
