The invention discloses a train positioning method. The method is characterized in that images in a track are acquired in real time, a track positioning point image detection model is adopted to accurately detect a positioning mark, accurate positioning is realized; the positioning mark is flexible and convenient to select, and the construction difficulty is reduced; a track position image with atarget detection frame is obtained through preliminary screening of a track positioning point image detection model, feature extraction, dimensionality reduction and clustering operation are performedon the track position image, screening is performed multiple times, and an accurate track positioning point image is obtained.

    本发明公开了一种列车定位方法,通过实时采集轨道内的图像,并采用轨道定位点图像检测模型,精确检测定位标志,实现精确定位,定位标志的选择灵活、方便,且减少了施工难度;通过轨道定位点图像检测模型初步筛选得到具备目标检测框的轨道位置图像,再对其进行特征提取、降维和聚类操作,多次筛选,得到准确的轨道定位点图像。
