A system and method for daylight inspection of a surface, such as a railroad track, is disclosed. The disclosed system includes lasers, cameras, and a processor. The lasers are positioned adjacent the surface. The laser emits a beam of light across the surface at a combined intensity of at least 0.15 watts of intensity per inch of width of the surface, and the camera captures images of the surface having the beam of light emitted thereon. The camera includes a bandpass filter which passes only a band of light corresponding to a dip in solar radiation. The laser is selected to provide an emitted light beam which is more intense than the solar radiation at the dip. The processor formats the images so that they can be analyzed to determine various measurable aspects of the surface. The system and method includes one or more algorithms for determining these measurable aspects of the surface.

System and method for inspecting surfaces using optical wavelength filtering

A method to increase the accuracy of the interpolation of railroad mileposts is disclosed. Based upon image data and data provided in customer track charts, reference points are selected along the track, and their location is verified using GPS data. Once verified, the locations of various points between the reference points are determined using mathematical interpolation.

Methods for GPS to milepost mapping

A system and method for determining rail seat abrasion of a rail road track is disclosed. An inspection system comprises lasers, cameras, and processors adapted to determine whether rail seat abrasion is present along the track. The processor employs a mathematics based algorithm which compensates for tilt encountered as the inspection system moves along the track.

Tilt correction system and method for rail seat abrasion

A system and method for inspecting railroad track is disclosed. The disclosed system includes lasers, cameras, and a processor. The lasers are positioned adjacent the track. The laser emits a beam of light across the railroad track, and the camera captures images of the railroad track having the beam of light emitted thereon. The processor formats the images so that they can be analyzed to determine various measurable aspects of the railroad track. The disclosed system can include a GPS receiver or a distance device for determining location data. The measurable aspects that can be determined by the disclosed system include but are not limited to the spacing between crossties, the angle of ties with respect to rail, cracks and defects in surface of ties, missing fastener components, misaligned fastener components, sunken tie plates, raised spikes, rail wear, gage of rail, ballast height relative to ties, size of ballast stones, and break or separation in the rail. The system includes one or more algorithms for determining these measurable aspects of the railroad track.
