The invention provides an image-based track extraction technology. The method comprises the following steps: installing a vehicle-mounted camera to obtain priori information, performing image Gaussianprocessing and marginalization, identifying a track in a close-range range, and identifying a track in a long-range. According to the method, the track can be recognized in real time in the train running process, and the problem of foreign matter invasion in track obstacle detection is solved to a certain extent, so that a driver is reminded to carry out pre-judgment, and the reliability and safety of train running are improved.

    本发明提出一种基于图像的轨道提取技术,该方法包括:安装车载摄像机获取先验信息,图像高斯化和边缘化,识别近景范围的轨道,识别远景范围的轨道。该方法能在列车行驶过程中实时识别轨道,并且一定程度上解决了轨道障碍物检测中异物入侵的问题,从而提醒驾驶员进行预判,提升列车运行的可靠性和安全性。
