Abstract
A method, performed by a computer having a processor and system memory, for calibrating a tie height of a ballast profiling rail vehicle having a remote sensing system, includes traversing the rail vehicle along a first calibration section of railroad track at a calibration speed, detecting, using the remote sensing system, a plurality of height to tie measurements in the first calibration section, establishing a rolling median average of the height to tie measurements, and determining a calibration tie height relative to the rail vehicle based upon the rolling median average.
