이미지프로세싱을 이용한 자갈궤도 자갈입자의 입도분포 분석

초록

Ballast track has been used widely because of its flexibility (e.g., easy maintenance and low initial construction cost). However, increasing traffic and speed require frequent maintenance. One of the affecting factors on ballast performance would be gradation and shape of ballast materials. This study investigates the applicability of digital image processing technique to evaluate gradation of ballast with two dimensional images. Shortest length and averaged thickness of ballast particles results in reasonable gradation, comparing with the gradation obtained by sieve analysis.
