现有技术中,ETC系统在确定车辆的通行费用时,主要是通过读取OBU中记录的车型信息来进行确定的,即认卡不认车,然而OBU中记录的车型并不一定是车辆的实际车型,例如用户注册时提交的是小型车的信息,但最终将电子标签OBU安装在大型车上使用,以此来减少高速通行费用。

图2是根据本申请实施例的信息处理方法的示意性流程图。图2的方法可以由服务器执行,其中,可以是图1中的服务器130。当然,图2的方法也可以由其他设备执行,本申请实施例对此不作限定。
图2的方法可以包括210-220,下面分别对210-220进行详细描述。
在210中,获取目标车辆的行驶数据。
可选地,目标车辆的行驶数据可以包括以下中的至少一种:目标车辆所在的经度、纬度、高度、方向、速度、位移、X方向的线性加速度、Y方向的线性加速度、Z方向的线性加速度等。其中,X、Y、Z表示空间直角坐标系中的X轴、Y轴和Z轴。
可选地,服务器通过采集目标车辆上安装的车载装置发送的信号,可以获取到目标车辆的行驶数据。
可选地,服务器可以按照固定频率采集车载装置发送的信号。其中,服务器采集传感器信号的频率可以为1s或者0.1s等,本申请实施例对此不作限定。
可选地,车载装置发送的信号可以为传感器信号。
其中,传感器信号可以包括但不限于车载装置接收卫星导航系统发送的该车载装置的定位信息,以及从车载装置内置的三轴加速度计中读取的空间加速度信息。其中,目标车辆所在的经度、纬度、高度、方向、速度、位移等一系列行驶数据可以组成目标车辆的定位信息,X、Y、Z三个方向的线性加速度等行驶数据可以组成目标车辆的加速度信息。
可选地,目标车辆上安装的车载装置可以将目标车辆一定时间段内的行驶数据发送给服务器。其中,该一定时间段内的行驶数据可以是一天的行驶数据,也可以是两天或一周的行驶数据等,本申请对此并不限定。
可选地,车载装置也可以将目标车辆当前时刻的行驶数据实时地发送给服务器。
应理解,由于地形遮挡、天气状况等情况可能会导致服务器采集的信号的强度减弱,或者因受到干扰源的影响,甚至是某时刻刚好处于卫星定位盲区等原因,可能会导致GPS接收器计算出现偏差,从而可能使目标车辆的行驶数据中出现噪声数据。
因此,服务器可以识别行驶数据中的噪声数据,并且修正噪声数据,以得到修正后的行驶数据。此过程的实现方式可以有很多种,本申请实施例对此不作具体限定。
可选地,噪声数据可以表示服务器接收的行驶数据中出现偏差的数据。
例如,目标车辆t时刻处于东经103度、北纬34度的位置,服务器获取到的目标车辆t时刻位置为东经115度、北纬41度,则可以确定服务器获取到的目标车辆t时刻的行驶数据为噪声数据。
可选地,服务器可以计算t时刻前后时间段内的行驶数据的均值和方差,然后将t时刻的行驶数据与方差的倍数进行比较,若t时刻的行驶数据大于方差的倍数,则可以确定t时刻的行驶数据为噪声数据。
当然,服务器也可以计算t时刻前后时间段内的行驶数据的均值和标准差,通过标准差得到方差后,将t时刻的行驶数据与方差的倍数进行比较,若t时刻的行驶数据大于方差的倍数,则可以确定t时刻的行驶数据为噪声数据。
可选地,车载装置可以通过GPS,以一定的更新率得到目标车辆的行驶数据,如目标车辆的经度和纬度,然后将该行驶数据发送给服务器。示例性地,GPS的更新率可以为1s,也可以为0.1s。
例如,若服务器要检测目标车辆t时刻的行驶数据是否为噪声数据,可以先计算时段t-k,t-(k-1),t-(k-2),…,t-1与t+1,…,t+(k-2),t+(k-1),t+k所对应的经度和纬度的均值与标准差,然后判断目标车辆t时刻的经度和纬度的值是否在三倍方差的范围内。若超出范围,则可以确定t时刻的行驶数据为噪声数据。
应理解,本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例,而非限制本申请实施例的范围。
在识别出行驶数据中的噪声数据后,服务器可以基于上述提到的均值来来修正噪声数据。
可选地,服务器可以用该均值替换噪声数据,得到初修正数据,再结合地图中的道路,修正该初修正数据。
作为一种示例,服务器可以根据目标车辆的行驶轨迹,大致确定目标车辆行驶在哪条道路上。具体地,服务器可以确定以初修正数据的定位点为圆心,以最大定位误差为半径的圆。与该圆相交的道路可以组成道路集合,该道路集合中包括最佳匹配道路。
然后服务器可以确定最佳匹配道路和修正后的行驶数据的定位点。具体地,服务器可以确定该定位点到与该圆相交的道路的投影距离,将投影距离最短的道路确定为最佳匹配道路,最佳匹配道路上的投影点则为修正后的行驶数据的定位点。
可选地,上述提到的目标车辆的行驶轨迹可以由目标车辆的一系列行驶数据按时间顺序排列得到。
可选地,上述提到的最大定位误差可以从GPS中读取到。正常情况下,GPS的定位误差在10-20米以内。
可选地,t时刻的道路匹配结果可以以t-1时刻的道路匹配结果为基础,若t-1时刻的道路匹配结果位于t时刻匹配的道路集合中,则服务器可以将t-1时刻的道路确定为t时刻的最佳匹配道路;若t-1时刻的道路匹配结果没有在t时刻匹配的道路集合中,则服务器可以将投影距离最短的道路确定为t时刻的最佳匹配道路。
例如,假定t时刻的行驶数据为噪声数据,GPS读到的最大定位误差为20米,服务器用t时刻前后时间段内的行驶数据的均值替换该噪声数据后,可以得到t时刻的初修正数据。然后服务器可以确定以t时刻的初修正数据的定位点为圆心、以20米为半径的圆,与该圆相 交的道路有L1、L2和L3。
然后服务器可以分别确定从t时刻初修正数据的定位点到L1、L2和L3的投影距离,将投影距离最短的道路确定为最佳匹配道路,如t时刻的初修正数据到L1的投影距离为5米,t时刻的初修正数据到L2的投影距离为3米,t时刻的初修正数据到L3的投影距离为2米,则可以确定L3为最佳匹配道路,L3上的投影点为修正后的t时刻行驶数据的定位点。
可选地,服务器可以基于模型识别行驶数据中的噪声数据。其中,服务器可以通过目标车辆行驶数据中的位移和加速度进行卡尔曼滤波得到最优估计模型,基于得到的最优估计模型,识别行驶数据中的噪声数据。
示例性地,假设已知t-1时刻目标车辆的行驶数据,则有:
v
t=v
t-1+u
t×Δt (2)
其中,下标t表示目标车辆t时刻的行驶状态,下标t-1表示目标车辆t-1时刻的行驶状态,p表示目标车辆的位移,v表示目标车辆的速度,u表示目标车辆的加速度。
则可以得到目标车辆t时刻的状态预测公式:
其中,
也可以将目标车辆的状态空间模型写为:
x
t=Fx
t-1+Bu
t+w
t (4)
其中x
t包含了观测的目标,如位移、速度;w
t是过程噪声,符合高斯分布。
上述技术方案,卡尔曼滤波器建立在动态过程之上,由于目标车辆位移、速度的不可突变特性,这样就可以通过目标车辆t-1时刻的状态预测t时刻的状态,从而识别出噪声数据。比如目标车辆t-1时刻加速度为零,t时刻速度却发生了变化,可以确定t时刻有观测误差,t时刻的行驶数据为噪声数据。
可选地,车载装置可以通过GPS和加速度积分,以一定的更新率得到目标车辆的定位信息,然后将该行驶数据发送给服务器。示例性地,加速度积分的更新率包括但不限于0.1s或0.01s等。
可选地,服务器可以基于最优估计模型,修正识别出来的噪声数据。具体地,服务器可以基于该最优估计模型,初修正噪声数据,得到初修正数据。再结合地图中的道路,修正初修正数据。
服务器结合地图中的道路修正初修正数据的具体实现过程上述内容已经详细描述过了,为了内容的简洁,此处不再赘述。
如图3所示,左图为初修正后目标车辆的行驶轨迹,右图为修正后目标车辆的行驶轨迹,从图3中可以看到,初修正后,目标车辆的部分定位点并非行驶在道路上,服务器结合地图中的道路,再次对初修正数据进行修正后,目标车辆的定位点都在道路上。
上述技术方案,由于确定目标车辆的实际车型是基于目标车辆的行驶数据的,服务器识 别出行驶数据中的噪声数据并对其进行修正,可以增加行驶数据的准确率,从而服务器根据行驶数据确定的目标车辆的实际车型的准确度较高。
在220中,根据行驶数据中的第一行驶数据,确定目标车辆的实际车型。
可选地,车型可以表示为与车辆的通行费对应的车辆型号,如7座以内客车、超过40座的客车、载重5至10吨的货车等。
可选地,第一行驶数据可以表示目标车辆一定时间段内的行驶数据。其中,该一定时间段可以为一天,或者一周等。
在本申请实施例中,目标车辆可以包括一个车辆,也可以包括多个车辆,本申请对此不作限定。
可选地,当目标车辆包括一个车辆时,服务器可以根据目标车辆的行驶数据,实时地确定目标车辆的实际车型。
可选地,当目标车辆包括多个车辆时,服务器可以根据获取到的预设时间段内的多个车辆的第一行驶数据,在一定的时间离线确定该多个车辆的实际车型。示例性地,该预设时间段可以为一天。
例如,服务器可以在每天晚上12点,根据当天获取到的多个车辆的第一行驶数据,离线确定该多个车辆的实际车型。
可选地,服务器也可以根据修正后的行驶数据中的第一行驶数据,确定目标车辆的实际车型。
220的实现方式可以有很多种,下面结合图4-图7,对220的具体实现方式进行详细的举例说明。
图4是图2中220的一种可能的实现方式的示意性流程图。图4的方法可以包括410-420。
在410中,根据第一行驶数据,确定目标车辆的行驶时间分布和/或行驶轨迹分布。
可选地,波形模式可以用于表征目标车辆的行驶时间分布。
可选地,轨迹模式可以用于表征目标车辆的行驶轨迹分布。
也就是说,服务器可以根据第一行驶数据,确定目标车辆的波形模式和/或轨迹模式。
服务器可以根据预设时间段内目标车辆的第一行驶数据,确定目标车辆的波形模式。可选地,该预设时间段可以是一个小时,也可以是一天,还可以是一周,本申请对此不作限定。
示例性地,服务器可以根据目标车辆一天中每小时的行驶时间,以及一周中每天的行驶时间分布情况,确定目标车辆的波形特征,然后使用聚类算法可以识别出目标车辆的波形模式。
可选地,波形特征可以包括目标车辆每天的驾驶总时长、每周的驾驶总时长、连续驾驶时间、两次驾驶时间间隔等。
可选地,聚类算法可以为k-means算法、clarans算法、birch算法等。
图5为大车和小车在一天中的行驶时间分布图。其中,虚线表示大车的波形特征,实线表示小车的波形特征,横轴是一天中的24个小时,纵轴代表横轴对应的时段内大车和小车一共行驶了多久(0-1小时)。从图5中可以看到,大车和小车的波形特征不同:小车主要集中在上下班时间使用,而大车的驾驶时间分布比较均匀,并且一天的驾驶总时长也远大于小车。
服务器可以根据目标车辆的第一行驶数据,确定目标车辆的轨迹模式。
在一种实现方式中,服务器可以根据目标车辆的第一行驶数据,识别出目标车辆的停留 点,并根据识别出的停留点的出现频率,确定目标车辆的常驻点。服务器可以结合地图信息,确定目标车辆常驻点的地理位置,如常驻点的地理位置可以为加油站、学校、写字楼、小区、建材市场等。基于常驻点的地理位置,将常驻点中的频繁项集进行组合与连接,从而可以得到目标车辆的轨迹模式。
可选地,停留点可以由目标车辆的一组实际的定位点构成,它并不是指目标车辆速度为零的点。如图6所示,目标车辆的定位点P3、P4、P5和P6可以构成停留点s。
与其它定位点相比,停留点可以具有更重要的信息。例如,货车大多出现在加油站,家用车经常往返于小区、公司等区域。
可选地,常驻点可以表示在一定的时间内出现频率较高的停留点。
例如,停留点1在一天时间内出现了两次,停留点2在一天时间内出现了一次,停留点3在一天时间内出现了五次,则可以确定停留点3为常驻点。
可选地,频繁项集可以表示经常同时出现的多个常驻点。例如,仓库1、加油站1以及加油站2这三个常驻点常常一起出现,则可以将仓库1、加油站1以及加油站2表示为频繁项集。
可选地,可以将时间相邻较近的频繁项集组合在一起,并按时间先后顺序将它们进行连接。
例如,仓库1、加油站1和加油站2为频繁项集1,仓库2、加油站2、加油站1和仓库1为频繁项集2,频繁项集1和频繁项集2时间相邻较近,并且频繁项集1经常先出现,频繁项集2经常后出现,因此,将频繁项集1和频繁项集2进行组合与连接后可以得到“仓库1-加油站1-加油站2-仓库2-加油站2-加油站1-仓库1”的轨迹模式。
在一种实现方式中,服务器在识别目标车辆停留点的过程中,可以检测目标车辆行驶轨迹中的每个定位点,然后可以依次以目标车辆的不同定位点为圆心,以距离阈值为半径确定圆,在每个圆范围内的点可以组成给一个集合。在每个圆内,确定时间最早与最晚的点,并计算出时间差值,即定位点之间的最大时间差值,然后服务器可以将该最大时间差值与时间阈值进行比较,若该最大时间差值大于时间阈值,则可以确定该最大时间差值所在圆的圆心为候选停留点。然后计算所有候选停留点的中心点,该中心点即为目标车辆的停留点。
可选地,服务器可以用关联分析算法从目标车辆的常驻点中挖掘出频繁项集。
可选地,关联分析算法可以包括但不限于FP-growth算法和apriori算法等。
例如,如图6所示,P1,P2,P3,…,P8为目标车辆的定位点,令距离阈值为Y,时间阈值为H。服务器依次以P1,P2,P3,…,P8为圆心、以Y为半径确定圆。比如以P3为圆心的圆内,有P2,P3,P4,P5,P6五个定位点,这五个定位点可以组成一个集合,该集合中时间最早的点为P2,时间最晚的点为P6,计算P2与P6之间的时间差值,将计算得到的时间差值与H进行比较,若时间差值大于H,则可以确定P3为一个候选停留点,以相同的方法可以确定其余七个定位点是否为候选停留点。
若最终确定P3,P4,P5,P6为候选停留点,确定包围P3,P4,P5,P6的最小的圆,如图6所示,虚线表示的圆为包围P3,P4,P5,P6的最小的圆,然后计算出该圆的圆心,该圆心即为目标车辆的停留点。
在420中,根据目标车辆的波形模式和/或轨迹模式,确定目标车辆的实际车型。
在一种可能的实施例中,服务器可以根据至少一个波形模式和/或轨迹模式与至少一个车型的对应关系,以及目标车辆的波形模式和/或轨迹模式,确定目标车辆的实际车型。
可选地,一个波形模式和/或轨迹模式可以对应一个车型。
可选地,多个波形模式和/或轨迹模式也可以对应一个车型。
可选地,服务器可以利用样本车辆的行驶数据得到对应关系。
示例性地,服务器可以根据样本车辆中每个车辆的行驶数据,得到每个车辆分到多种车型中每个车型的概率,以及每个车辆的波形模式和/或轨迹模式;然后可以将第一车辆对应的车型概率大于第一阈值的车型确定为第一车辆的实际车型,再基于确定的第一车辆的实际车型与第一车辆的波形模式和/或轨迹模式,可以得到该对应关系。
例如,令第一阈值为0.9,若根据样本车辆中车辆A的行驶数据,可以得到车辆A的波形模式为波形模式1,并且车辆A分到小车的概率为0.97,分到大车的概率为0.03,则可以确定车辆A的实际车型为小车,以及小车对应波形模式1。服务器确定的目标车辆的波形模式为波形模式1,则服务器可以根据波形模式1与小车的对应关系,以及目标车辆的波形模式,确定目标车辆的实际车型为小车。
上述技术方案,服务器在确定目标车辆的行驶时间分布和/或行驶轨迹分布后,可以根据提前确定好的行驶时间分布和/或行驶轨迹分布与车型的对应关系,直接找到目标车辆的行驶时间分布和/或行驶轨迹分布对应的车型,这样可以快速地确定目标车辆的实际车型。
在一种可能的实施例中,当目标车辆包括多个车辆时,服务器可以根据多个车辆中每个车辆的第一行驶数据,得到每个车辆分到多种车型中每个车型的概率,以及每个车辆的波形模式和/或轨迹模式,将第一车辆对应的车型概率大于第一阈值的车型确定为第一车辆的实际车型。
可选地,服务器可以根据多个车辆中每个车辆的第一行驶数据以及分类模型,得到每个车辆分到多种车型中每个车型的概率,具体实现方式将在图7中进行阐述,此处不再赘述。
例如,令第一阈值为0.9,服务器可以根据多个车辆的第一行驶数据得到每个车辆分到大车和小车的概率,如目标车辆1分到大车的概率为0.4,分到小车的概率为0.6;目标车辆2分到大车的概率为0.2,分到小车的概率为0.8;目标车辆3分到大车的概率为0.99,分到小车的概率为0.01,由于目标车辆3分到大车的概率大于第一阈值0.9,因此,可以确定目标车辆3的实际车型为大车,标记目标车辆3,并且将目标车辆3确定为大车的代表样本。
应理解,在这种方式下,服务器可以确定实际车型的车辆数量较少,如目标车辆中有100辆车,服务器可以确定的实际车型的车辆可能只有30辆,因此,还需要进一步确定剩余车辆的实际车型。
在一种实现方式中,服务器可以将多个车辆的波形模式和/或轨迹模式中相同的波形模式和/或轨迹模式组成一类波形模式和/或轨迹模式,则可以得到多类波形模式和/或轨迹模式。服务器可以针对每类波形模式和/或轨迹模式对应的车辆,确定第一车辆在每种车型的车辆中所占的比例,以及第一车辆所占的比例大于第二阈值的目标车型。针对所述每类波形模式和/或轨迹模式对应的车辆中的第二车辆,可以将所述目标车型确定为所述第二车辆的车型。
其中,第二车辆为多个车辆中除第一车辆之外的车辆。
可选地,第一车辆也可以称为标记车辆,第二车辆也可以称为未标记车辆,本申请不作限定。
例如,令第二阈值为0.9,服务器确定的多类波形模式有:波形模式1、波形模式2、波形模式3……,多类轨迹模式有轨迹模式1、轨迹模式2、轨迹模式3……。假定波形模式1中有50个车辆,标记车辆有30个,未标记车辆有20个,其中,在标记车辆中,有17个大 车,13个小车,大车的比例为0.57,小车的比例为0.43;轨迹模式1中有30个目标车辆,标记车辆有15个,未标记车辆有15个,标记车辆中有14个小车,1个大车,小车的比例为0.93。由于轨迹模式1中标记车辆在两种车型的车辆中所占的比例大于0.9,因此可以将轨迹模式1中的未标记车辆的车型确定为小车。
本申请实施例中,术语“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。
上述技术方案,当满足一定的条件时,服务器可以将未标记车辆的车型确定为标记车辆的车型,这样服务器可以确定的实际车型的车辆数量能够明显增加。
图7是图2中220的一种可能的实现方式的示意性流程图。图7的方法可以包括710-720。
服务器可以根据目标车辆的第一行驶数据,实时地确定目标车辆的实际车型。
在710中,根据目标车辆的第一行驶数据以及模型,得到目标车辆分到不同车型的概率。
可选地,该模型可以由样本车辆在OBU中的注册车型以及样本车辆的行驶数据训练得到。
可选地,样本车辆的行驶数据可以为三轴加速度的统计特征。其中,三轴加速度的统计特征可以有很多种,本申请实施例对此不作具体限定。例如,加速度的统计特征可以包括以下中的至少一种:最大加/减速度、大于1m/s的加/减速度所占的百分比、加/减速度的标准差。
可选地,该模型可以为分类模型。其中,分类模型可以是随机森林、梯度提升决策树(gradient boosting decision tree,GBDT)、逻辑回归(logistic regression,LR)、支持向量机(support vector machine,SVM)、深度神经网络(deep neural network,DNN)等。
应理解,样本车辆有多少车型,得到的概率就为目标车辆分到这么多车型的概率。如样本车辆有5种车型,则服务器可以根据目标车辆的行驶数据以及分类模型,得到目标车辆分到5种车型的概率。
在720中,基于得到的概率,确定目标车辆的实际车型。
可选地,服务器可以将目标车辆分到不同车型的概率与第一阈值进行比较,若目标车辆分到某种车型的概率大于第一阈值,则可以将该车型确定为目标车辆的实际车型。
示例性地,令第一阈值为0.9,根据目标车辆的行驶数据以及分类模型,得到目标车辆分到大车的概率为0.95,分到小车的概率为0.05,则服务器可以确定目标车辆的实际车型为大车。
应理解,本申请实施例的各种实施方式既可以单独实施,也可以结合实施,本申请实施例对此并不限定。
本申请实施例,服务器识别目标车辆的实际车型是基于对目标车辆行驶数据的分析,由于不同车型的行驶数据不同,比如家用车主要集中在上下班时间使用,货车的驾驶时间比较均匀,即目标车辆的行驶数据和实际车型是对应的,因此通过行驶数据可以以较高的准确率识别出目标车辆的实际车型。
可选地,该方法还可以包括:基于实际车型,验证目标车辆的业务行为信息,或者输出目标车辆的业务行为信息。
可选地,业务行为信息可以包括非缴费信息和缴费信息。
可选地,非缴费信息可以包括服务器向路侧装置发送的指示信息,还可以包括目标车辆的经过时间,或者目标车辆的图片等。
作为一种示例,服务器可以将目标车辆的实际车型和注册车型进行比较,并向路侧装置发送指示信息,该指示信息用于指示目标车辆的实际车型和注册车型的比较结果。
可选地,若指示信息指示目标车辆的实际车型和注册车型相同,则路侧装置的自动栅栏机抬起,目标车辆通行;若指示信息指示目标车辆的实际车型和注册车型不同,则路侧装置禁止目标车辆通行。
可选地,路侧装置中可以有显示屏,若指示信息指示目标车辆的实际车型和注册车型不同,则显示屏不停地闪烁。
可选地,路侧装置中可以有报警装置,若指示信息指示目标车辆的实际车型和注册车型不同,则报警装置会报警,比如发出蜂鸣声;若指示信息指示目标车辆的实际车型和注册车型相同,则报警装置不报警。
作为一种示例,若目标车辆的注册车型和实际车型不一致,则服务器可以将目标车辆的经过时间、目标车辆的图片等存储到数据库中。
可选地,缴费信息可以包括目标车辆是否缴费的信息、已缴费信息和待缴费信息。
可选地,已缴费信息可以包括目标车辆缴费时OBU发出的注册车型,待缴费信息可以包括目标车辆的实际车型。
也就是说,基于实际车型,服务器可以对目标车辆的已缴费信息进行验证,或者输出目标车辆的待缴费信息。
可选地,服务器可以基于目标车辆的实际车型,向路侧装置输出目标车辆的实际车型,路侧装置可以根据该实际车型对目标车辆进行收费。
可选地,若目标车辆的注册车型和实际车型不同,则服务器可以将相关案例上报给系统进一步审查。对于系统反馈的结果,在下一轮训练分类模型时,服务器可以增加目标车辆的样本权重,并将与反馈结果不一致的目标车辆的注册车型信息更正为服务器确定的实际车型信息。
服务器可以检验目标车辆的实际车型与注册车型是否一致,若目标车辆的实际车型与注册车型不一致,比如车辆C的注册车型是小车,但服务器识别出的车型为大车,则服务器可以将所有不一致的案例上报给系统进行审核,比如疑似大车小标的有车辆C、车辆D等。服务器将不一致的案例上报给系统之后,可以再反馈给系统不一致案例中目标车辆的实际车型,比如车辆C-大车、车辆D-大车。服务器可以将车辆C与车辆D的注册信息中的车型改为大车,在下一轮中训练分类模型时,增大车辆C和车辆D所对应样本车辆的权重,且直接将车辆C和车辆D加入代表样本集合,即大车的代表样本中增加车辆C和车辆D。可选地,服务器可以基于实际车型,对目标车辆的已缴费信息进行验证。若服务器确定的缴费信息和目标车辆实际的缴费信息不一致,则服务器可以降低目标车辆的信用值,或者可以远程禁止目标车辆使用OBU,若目标车辆的车主没有做澄清处理且补请缴费金额,阻止目标车辆下一次进入高速。
上述技术方案,服务器基于实际车型,可以对目标车辆的已缴费信息进行验证,或者向路侧装置输出目标车辆的待缴费信息,路侧装置根据该待缴费信息对目标车辆进行收费,这样可以减少目标车辆大车小标的行为对运营商造成的损失。
可选地,服务器可以基于行驶数据中的第二行驶数据和目标区域,确定目标车辆驶出目标区域的时刻。
其中,该目标区域为收费站的区域。可选地,该目标区域可以为多边形。如图8所示, 实线表示的区域为目标区域。
可选地,服务器可以根据收费站的范围大小确定目标区域的范围。
可选地,第二行驶数据可以表示目标车辆t-1时刻和t时刻的行驶数据。
可选地,第二行驶数据可以为t-1时刻和t时刻目标车辆所在的经度和纬度。
可选地,若目标车辆t-1时刻在目标区域内部,t时刻在目标区域外部,则可以确定t时刻是目标车辆驶出目标区域的时刻。。
可选地,服务器可以基于目标车辆的第二行驶数据,判断目标车辆t时刻和t-1时刻是否在目标区域内部。
在一种实现方式下,服务器可以基于目标车辆的第二行驶数据,直接判断目标车辆t时刻和t-1时刻是否在目标区域内部。
可选地,服务器可以沿水平方向或垂直方向确定以目标车辆在t时刻和t-1时刻的定位点为端点的射线,根据射线与目标区域的交点数量,判断目标车辆t时刻和t-1时刻是否在目标区域内部。
若射线与目标区域的交点数量为奇数,可以确定目标车辆t时刻或t-1时刻在目标区域内部;若射线与目标区域的交点数量为偶数,可以确定目标车辆t时刻或t-1时刻未在目标区域内部。
如图9所示,点O1为目标车辆t-1时刻的定位点,O2为目标车辆t时刻的定位点。沿水平方向分别确定以点O1和O2为端点的射线。可以看到,以O1为端点的射线与目标区域有一个交点,以O2为端点的射线与目标区域有两个交点,因此,可以确定目标车辆t-1时刻在目标区域内部,t时刻在目标区域外部,确定t时刻为目标车辆驶出目标区域的时刻。
可选地,服务器还可以分别沿水平方向和垂直方向确定以目标车辆在t时刻和t-1时刻的定位点为端点的射线,即可以确定两条射线,根据这两条射线分别与目标区域的交点数量,判断目标车辆t时刻和t-1时刻是否在目标区域内部。
在一种实现方式下,服务器可以基于第二行驶数据,确定目标车辆t时刻和t-1时刻在最小外包区域内部,然后再判断目标车辆t时刻和t-1时刻是否在目标区域内部。
可选地,最小外包区域可以表示目标区域的近似范围,该最小外包矩形可以为矩形,如图8所示,虚线表示的区域为最小外包区域。
可选地,服务器可以获取最小外包区域两个对角的坐标,基于获取到的坐标可以确定最小外包区域的范围。基于目标车辆的第二行驶数据,可以得到目标车辆的经度和纬度数据,从而可以确定目标车辆在t时刻和t-1时刻的坐标。再基于目标车辆在t时刻和t-1时刻的坐标以及最小外包区域的范围,从而可以确定目标车辆在t时刻和t-1时刻在最小外包区域内部。
示例性地,若最小外包区域的两个对角的坐标分别为(3,1)和(6,4),目标车辆t时刻的坐标为(4,2),t-1时刻的坐标为(2,5),则服务器可以确定目标车辆t时刻在最小外包区域内部,t-1时刻没有在最小外包区域内部。
服务器确定目标车辆t时刻在最小外包区域内部后,可以进一步判断目标车辆t时刻是否在目标区域内部,判断的方法上述内容已经进行了详细地描述,此处不再赘述。
本申请实施例中,服务器先确定目标车辆是否在最小外包区域内部,若在最小外包区域内部,再判断是否在目标区域内部;若目标车辆不在最小外包区域内部,则可以直接确定目标车辆在目标区域外部,由于判断目标车辆是否在最小外包区域内部的速度较快,因此这样 可以快速地判断目标车辆是否在目标区域内部,从而可以实时地确定目标车辆是否要离开收费站。
可选地,服务器可以基于目标区域和最小外包区域建立空间索引,然后基于目标车辆在t时刻和t-1时刻的坐标、最小外包区域的范围以及空间索引,确定目标车辆在t时刻和t-1时刻在最小外包区域内部。
可选地,空间索引可以为R树空间索引。
服务器可以将所有收费站区域对应的最小外包区域确定为R树的叶子节点,父节点可以框住其子节点的所有区域,并形成一个最小边界区域。
例如,C、D、E、F、G、H、I、J表示八个收费站对应的最小外包区域,C、D、E、F离得较近,可以形成最小边界区域A;G、H、I、J距离较近,可以形成最小边界区域B,因此,可以确定C、D、E、F、G、H、I、J为叶子节点,A为C、D、E、F的父节点,B为G、H、I、J的父节点。服务器可以先判断目标车辆是否在A或B区域内,若在A区域内,则服务器继续判断目标车辆在C、D、E和F中的哪个区域,而不用再判断目标车辆是否在G、H、I、J区域。
上述技术方案,通过建立空间索引,服务器可以快速地判断目标车辆是否在最小外包区域内部。
服务器可以在目标车辆驶出目标区域的时刻,基于确定的实际车型,对目标车辆的已缴费信息进行验证。
可选地,该实际车型可以是服务器根据上述内容提到的目标车辆的第一行驶数据确定的,也可以是服务器根据目标车辆的图片、激光等其他方式确定的,本申请实施例对此不作具体限定。
可选地,服务器可以在目标车辆驶出目标区域的时刻,验证目标车辆是否缴与实际车型相应的费用,若目标车辆没有发生过缴费操作或缴的费与实际车型不对应,则服务器可以启动一系列措施。
作为一种示例,服务器可以将异常现象自动上报给系统,系统进行进一步审核。
作为一种示例,服务器可以降低目标车辆的信用值,当目标车辆的信用值降到一定程度时,服务器将禁止目标车辆上高速。
作为一种示例,服务器可以远程禁止目标车辆使用OBU,若车主没有做澄清处理且补请缴费金额,阻止下一次进入高速。
本申请实施例,服务器确定目标区域,根据目标区域的对角坐标可以确定目标区域的范围,并且基于目标车辆的行驶数据,即经度和纬度,可以确定目标车辆的坐标,通过目标区域的范围和目标车辆的坐标可以自动识别目标车辆进出收费站的行为,并且在目标车辆离开车费站时可以识别出目标车辆是否缴费,若服务器检测出来目标车辆缴费异常,则启动一系列防止目标车辆二次逃费的措施。这样可以减少目标车辆的逃费行为。
可选地,服务器可以根据目标车辆的行驶数据,确定预设时间段内目标车辆在高速公路的行驶里程数。基于目标车辆的实际车型和行驶里程数,输出目标车辆的待缴费信息。
可选地,预设时间段可以表示为目标车辆每次进入高速公路入口和离开高速公路出口之间的时间。
示例性地,服务器可以记录目标车辆每次上高速的收费站点,并且服务器可以向车载装置发送通知信息,该通知信息可以用于通知车载装置开启目标车辆的轨迹追踪。车载装置将 轨迹追踪的数据发送给服务器,服务器可以根据该数据确定目标车辆在每次进入高速公路入口和离开高速公路出口之间的这段时间内,在高速公路的行驶里程数,然后可以基于确定的目标车辆的实际车型和行驶里程数,输出目标车辆的待缴费信息。
当然,车载装置也可以全天都开启目标车辆的轨迹追踪,服务器可以根据目标车辆上高速的收费站点和轨迹追踪的数据,确定目标车辆在高速公路的行驶里程数。
上述技术方案,服务器可以根据目标车辆的行驶数据,如通过轨迹追踪识别出目标车辆真实的行驶里程数,这样可以避免目标车辆的倒卡行为,从而减少倒卡的逃费行为对运营商造成的经济损失。
