Machine Vision Rail Crack Detection Using LED Uniform Illumination Imaging
For the crack fault detection on railway rail,the main problems existing in the current detection technolo-gy based on machine vision include:(1)Without specific lighting design,the captured image will be missing details due to lighting;(2)The image processing technology is not perfect,resulting in failure detection with high precision;(3)The speed limit of the transmission equipment,resulting in the image information processing is not timely.Therefore,according to the characteristics of railway rail image information,this paper designs a specific uni-form lighting system and adopts the corresponding image crack detection technology to form a set of efficient rail crack detection system.Experiments show that the accuracy of the system can reach 98％.
