Detection System about Train Brake Discs' Cracks Based on Image Processing

Abstract:

The reliability of the brake disc is one of the main factors influencing running safety. This paper introduces the causes and harm of train brake disc crack, the application of digital image acquisition technology, and image processing function in MATLAB. We research a method of image preprocessing and subsequent processing by programming language, give effect drawing in each phase, and calculate the pixel size through effective extraction based on the crack characteristics. At last the condition of crack size and actual area is presented. The study can provide a reference for monitoring personnel replace the brake disc timely.
