Inspecting rail-wear status is critical to guarantee high-speed running safety, proper maintenance schedule, and low operating costs. A dynamic inspecting system based on machine vision is presented using near-infrared laser line projector, CCD (charged coupled device) camera and image processing technology for detection of rail wear parameters. The design of single-element laser-beam projector is...
Detecting rail-wear status is critical to guarantee high-speed running safety, proper maintenance schedule, and low operating costs. An automatic scheme has been presented using near-infrared laser line projector, Charged Coupled Device (CCD) camera and image processing technology for rail wear detection. After obtaining original rail images, a DLT (Direct Linear Transformation) algorithm is analyzed...
