本发明实施例提供一种高速公路费用清分方法及装置,所述方法包括:获取摄像头拍摄的路况视频,根据视频确定待清分车辆的行驶轨迹,并根据待清分车辆的行驶轨迹从视频中截取车辆图片;根据车辆的时空特征在所述车辆图片中提取正负样本,根据样本训练车辆表观特征提取器,并通过训练后的车辆表观特征提取器提取表观特征;将表观特征与其它车辆进行对比,根据结果得到第二路况视频中待清分车辆的出现路段,模拟待清分车辆的可能行驶路径;根据路况视频计算瞬时速度;根据可能行驶路径及瞬时速度确定行驶路径;根据所述行驶路径及所述行驶路径对应的收费标准在各高速路投资主体间进行费用清分计算。采用本方法能够更准确的实现高速路费用的清分。

    The embodiment of the invention provides a highway expense clearing method and device, and the method comprises the steps: obtaining a road condition video photographed by a camera, determining the driving track of a to-be-cleared vehicle according to the video, and capturing a vehicle image from the video according to the driving track of the to-be-cleared vehicle; extracting positive and negative samples from the vehicle picture according to the spatial and temporal features of the vehicle, training a vehicle apparent feature extractor according to the samples, and extracting apparent features through the trained vehicle apparent feature extractor; comparing the apparent characteristics with other vehicles, obtaining an appearing road section of the to-be-sorted vehicle in the second road condition video according to a result, and simulating a possible driving path of the to-be-sorted vehicle; calculating an instantaneous speed according to the road condition video; determining a driving path according to the possible driving path and the instantaneous speed; and according to the driving path and a charging standard corresponding to the driving path, carrying out fee clearing calculation among the highway investment main bodies. By adopting the method, clearing of highway cost can be realized more accurately.
