Route panorama acquisition and rendering for high-speed railway monitoring

With the rapid development of high-speed railway, the safety running of trains becomes extremely urgent. Video is a direct and effective manner for railway environment monitoring. In this paper, we propose a route panoramic representation to produce a virtual environment of the railway scene from a train-borne video, which provides an all-round display for the entire length of railway. We generate the route panorama from the forward motion video and then render 3D scene. The experimental results show many advantages of the representation in the large data storage, browsing, and examination. It will be used for railway safety checking, railway facility inspection and virtual sightseeing from the train in the future.
