Abstract
A system for inspecting railroad ties in a railroad track includes a light generator, an optical receiver and a processor. The light generator is oriented to project a beam of light across the railroad track while moving along the railroad track in a travel direction. The optical receiver is oriented to receive at least a portion of the beam of light reflected from the railroad track and configured to generate image data representative of a profile of at least a portion of the railroad track. The processor is configured to analyze the image data by applying one or more algorithms configured to find boundaries of a railroad tie and determine one or more condition metrics associated with the railroad tie.
