The db.XML file provided with your Velodyne HDL-64E contains all of the necessary data for the
proper alignment of the point cloud information gathered by the HDL sensor for each laser.
{vertical correction (deg), rotational correction (deg), distance correction (cm), vertical offset
(cm), horizontal offset (cm), minimum and maximum intensity (0-255)}.
When implemented properly, the image viewable from the Digital Sensor Recorder (DSR) will be
properly calibrated to provide an accurate visual representation of the environment in which the
sensor is being applied.
This data should also be used in any other program using the data generated by the HDL-64E.
