The invention discloses a train positioning method based on an overhead line system and accessory devices thereof. The method comprises the steps: S1, performing clear imaging on a contact suspension,an additional suspension, a supporting device, a positioning device and other surroundings in an overhead line system; S2, obtaining a clear image containing all complete overhead contact system accessory devices along the way; S3, preprocessing the high-definition image, and determining an overhead contact system accessory device area; S4, extracting features of an area where the accessory device is located by adopting HOG features; S5, selecting 10% of the contact network accessory device area samples as verification samples to extract SIFT features of the sample library images; and S6, recording video information transmitted by a 4C detection device in real time by using the vehicle-mounted computer, repeating the steps S1-S4 to obtain an image of the accessory device area of the overhead line system, extracting SIFT features of an image sample of the accessory device area, and comparing the SIFT features with the detection sample in the step 5.

    本发明公开了一种基于接触网及其附属器件的列车定位方法,包括S1、对接触网中接触悬挂、附加悬挂、支撑装置、定位装置及其他周围进行清晰成像;S2、获取包含完整沿途所有接触网附属器件清晰图像,S3、对高清图像进行预处理,确定接触网附属器件区域;S4、采用HOG特征提取附属器件所在的区域的特征;S5、从接触网附属器件区域样本中选取10%作为验证样本提取样本库图像的SIFT特征;S6、利用车载电脑实时录取4C检测装置传输的视频信息,重复步骤S1‑S4得到接触网附属器件区域的图像,提取附属器件区域图像样本的SIFT特征与步骤5中的检测样本进行比对。
