Velodyne VLP32-C scaling issue

Hi all. I have a unit of VLP 32-C (32 channels puck) lidar in my possession. For some reason the support for this model is only available when building from source and is not included in the apt-get distribution (ROS Indigo over Ubuntu 14.04).

Nevertheless, it seems to work quite fine, but when things began to get fishy we made measurements with other instruments, and we found out that the lidar reports it's pointcloud at roughly half of its true size. Every point is at half the distance and height of what it should be.

I did not find any argument in the launch file to control this. Could it be hardcoded in the calibration file? Did anyone else run into this problem? PS I also tried it on various computers.

Many thanks to all, Steve.

The VLP32C uses a different distance scaling factor than other sensors. It seems like that's accounted for in https://github.com/ros-drivers/velody... .
