Disclosed is a media platform for multi-projection technology-based virtual reality train. According to embodiments of the present invention, the tunnel wall media playback through attachment of a urban railway vehicle display system, remote content management through a web server, real-time collection and management of a content playback history, screen distortion correction by a tunnel wall separation distance and bending, remote projectile management system, automatic synchronization of multi-display content playback, synchronization between a train real-time operation schedule and a content playback schedule, image/video synthesis rendering according to a template, and safety content automatic playback in emergency techniques may be provided. A tunnel test method for projection comprises the steps of: collecting first distance information; collecting second distance information; predicting a shape of a plane of incidence; and determining a warping function. 멀티 프로젝션 기술 기반 가상현실열차를 위한 미디어 플랫폼이 개시된다. 실시예들에 따르면, 도시철도 차량 디스플레이 시스템 부착을 통한 터널 벽면 미디어 재생, 웹 서버를 통한 원격 콘텐츠 관리, 콘텐츠 재생 이력 실시간 수집 및 관리, 터널 벽면 이격거리 및 굴곡에 의한 화면왜곡 보정, 원격 투사체 관리 시스템, 다중 디스플레이 콘텐츠 재생 자동 동기화, 열차 실시간 운행-콘텐츠 재생 스케줄 간 동기화, 템플릿 따른 이미지/영상 합성 렌더링, 비상시 안전콘텐츠 자동 재생 기술들이 제공될 수 있다.
