发明名称 SYSTEM AND METHOD FOR INSPECTING SURFACES USING OPTICAL WAVELENGTH FILTERING
摘要 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.
