Abstract
A method for optically examining a route such as a track includes obtaining one or more images of a segment of a track from a camera mounted to a rail vehicle while the rail vehicle is moving along the track and selecting a benchmark visual profile of the segment of the track. The benchmark visual profile represents a designated layout of the track. The method also can include comparing the one or more images of the segment of the track with the benchmark visual profile of the track and identifying one or more differences between the one or more images and the benchmark visual profile as a misaligned segment of the track.
