摘　　要：为了缓解地铁乘客乘坐地铁时的紧张焦虑情绪,设计了一种地铁列车地面实景播报系统。该系统由控制主机、投影仪、条形屏幕、定位模块和测距模块组成,能让乘客乘坐地铁时欣赏到地面沿途风景。分析评价结果表明,地铁区间运行时间和停靠时间相对固定,误差很小可通过插入报站信息或广告实现无缝对接,不会影响实景播报系统的播放效果。To relieve the tension and anxiety of subway passengers,a metro train ground real scene broadcasting system is designed.The system consists of a control host,a projector,a bar screen,a positioning module and a ranging module,allowing passengers to enjoy the scenery along the ground while taking the subway.The analysis and evaluation results show that the running time and stopping time in the subway interval are relatively fixed,and the error is small.The seamless docking can be achieved by inserting station information or advertisements,and the broadcasting effect of the live broadcast system will not be affected.
