Abstract：In order to monitor the wearof the carbon skateboardof thecolector shoe inreal time and ensure the normalandstable operationof thesubway，animproved non-contact measurement methodof the thicknessof the carbon skateboard of the colector shoe was proposed.The measurement method mainly included two parts ：carbon slide area positioning and thickness measurement.The area positioning of carbon slide plate was mainly realized by image procesing technologies suchas edge detection，binarization，long line detection and morphological operation. Thickness measurementfirst located the long straight lineof the upper edge of the carbon slide plate and the long straight lineof the lower edgeofthe base，thencalculatedthe heightdiferenceofthesameordinateof all pixels on theupper and lowerlong edges，and thenfoundout the height diference with the most votes according to the voting mechanism and converted the actual height diference according to the pixel size，and finally subtracted the fixed value from the lower edgeof thebase to thelower edgeof thecarbon slide plate tocalculate thecurrent real thickness value of thecarbon slide inreal time.According tothe practical application of Shanghai Metro Line17，the error between the measurement results of the method and the manual measurement results was lessthan or equal to （20 0.02mm ，and the average detection time of a single image was149.5 milliseconds.
