The invention discloses a train positioning system and method based on image recognition and speed integration, and the method comprises the following steps: firstly, collecting an image in front of a train; secondly, processing the image data in front of the train to obtain text information of line identifiers on the hectometer marks, and obtaining specific positioning of the position of each hectometer mark in combination with a corresponding line map; finally, when the train is located in the section between the two hundred-meter marks, the train running speed information is combined, the distance between the train and the hundred-meter marks is calculated, and train positioning is achieved. According to the method, the hectometer marks and the train speed information are combined, continuous positioning of the train is achieved, based on existing hectometer mark line marks and existing speed information of a train control management system, only a high-definition camera and an intelligent analysis host need to be installed on the train, cost is low, and feasibility is high.
本发明公开了一种基于图像识别与速度积分的列车定位系统及方法,包括如下步骤:首先,采集列车前方的图像;其次,对列车前方图像数据进行处理,得出百米标上线路标识的文本信息,并结合对应的线路地图,得出每个百米标位置的具体定位;最后,当列车位于两个百米标之间的区段时,结合列车运行速度信息,计算得出距离百米标的距离,实现列车定位。本发明结合了百米标和列车速度信息,实现了列车的连续定位,由于基于现有的百米标线路标识,和列车控制管理系统现有的速度信息,只需在车上安装高清摄像机和智能分析主机,成本低,可行性高。
