Abstract
<p>To properly maintain and manage track surfaces, the amount of collapsed settlement of a ballast bed must be determined. However, high maintenance costs make it difficult for railway operators to fully maintain and manage track surfaces. Therefore, we propose a method of estimating the shape of the ballast bed using Dense Inverse Search (DIS) optical flow in images captured using a camcorder, which is inexpensive. This paper describes the outline of the method, an evaluation of its accuracy through simulation and model experiments, and the results of applying the method to actual images captured using a camcorder.</p>
