Development of a Vision based Railway Platform Safeguard

초록

The CCTV is the most common safeguard, widely used in many railway applications. However, It has a functional restrictions providing only video information about preset monitoring area, such as boarding platform, and so on. In the system, operators should observe multiple screens continuously during whole day at the station office. It is very hard to detect and keep up with the accident immediately. To solve that problem, we propose a vision based railway platform safeguard using stereo image processing technology. It detects passenger’s danger and informs operators with video and alarms. Moreover, the system automatically deals with the accidents, such as automatic train stop, and broadcasting for passenger’s safety on the platform about the accident. In the paper, we present the system configuration, detection process and experimental result.
