A Visual Simulation Method for Considering Installation Site of Wayside Facilities using Video Sequences from the Train Cab

Abstract

Recently, constructions of obstruction-warning signals and emergency buttons have been urgently needed at level crossings. However, the construction of these wayside facilities involves considerable inefficiency because it requires a joint survey or instruction to check these visibility from the train cab. Therefore, we have developed a simulator that overlays wayside facilities image on video sequences by estimating a three-dimensional position using our rail extraction method. In this paper, we present the concept of the simulator, details of the method, and an accuracy verification based on actual video sequences.

<b>Visual Simulation Method for Installation of Wayside Facilities Using Video Sequences</b>

“…In order to deal with this problem, a simulation method has been developed [1,2,3], whereby camcorder footage taken from the driver's cab is used and the virtual line of sight of the driver of wayside signals on the track is displayed by using overlaid images. This simulation method is used to adjust and establish scheduled wayside signal positions.…”
