Camera View Control for Railway Forward Looking System

Abstract

In a railway train forward looking system, it is necessary to capture a clear image of the rails in the distance using a cab-mounted camera. Therefore, we developed an improved railway train forward looking system. The current system has certain function in term of camera view control. However, since the rail extraction result of the system is discontinuous in time, the system cannot operate the camera view control smoothly. Therefore, we improved the system using rail extraction algorithm to obtain a favorable zoomed camera image. In this paper, we report on the algorithm and test results.
